PREFACE.

WueEN this work was commenced, a little more than twelve years ago, the main object

in view was the collection of the widely scattered data bearing upon the phyto-

geography of the region, in order to ascertain to what extent the phenomena agreed

with, or deviated from, those obtaining in the Animal Kingdom, and also to supply as

complete a synopsis of the flora as possible, so that its general character, relationships,

and connections might be critically elaborated. Nevertheless, it was hoped that it

would at the same time prove a substantial and useful contribution to Systematic

Botany ; and as the work proceeded greater attention was bestowed upon this branch

of the subject, so that ultimately it grew far beyond the dimensions originally laid

down. As this great task was undertaken by one person, it was necessary to keep it

within limits as narrow as were consistent with the aim in view, to ensure a reasonable

prospect of its being completed. A critical determination of the vast amount of

material in the Kew Herbarium alone was out of the question, to say nothing of the

supplemental collections in other establishments; yet it was difficult to decide where

to draw the line. At first it was thought practicable to include the named materials

at Kew, the British Museum, and Paris—the first forming a wide and trustworthy

basis for genera, and largely also for species, resulting from the labours of Bentham

and Hooker, in connection with their now happily completed invaluable ‘Genera

Plantarum ’; but this plan had to be abandoned in consequence of the risk of confusion

arising from diverse determinations in the various herbaria; and it was decided not to

attempt doing more than could be accomplished at Kew. ‘This course has been

adversely criticised, but having intentionally and purposely thus curtailed the scope

of the work, such criticisms call for no further reply. Considering that, for obvious

| a 2

reasons, anything very closely approaching completeness could not have been attained

had there been half a dozen workers in the field, instead of only one, the omission of

some small historical collections is of the very slightest importance. Notwithstanding

the fact that the work has been substantially restricted to the Kew Herbarium and

Library, it has been, as already mentioned, considerably extended in a direction not

originally contemplated. For the purposes in view it was thought that we might very

largely rely on the names as we found them in the Kew Herbarium, and describe

only such very evident novelties as did not involve too great an expenditure of time.

In this manner the whole of the Polypetale was written out, and in the hands of the

Editors, when an offer was received from Drs. Parry and Palmer to present the first

set of a large collection of dried plants, chiefly from the State of San Luis Potosi, on

the condition that we named the whole of them and embodied them in the “ Biologia.”

To do this properly involved an enormous additional expenditure of time and money;

yet the offer was accepted, and the writer, aided by his colleagues at Kew, spent

nearly seven months on this collection, and the investigations it entailed, thereby

greatly enhancing the value of the Enumeration, without considerably increasing its

bulk.

This critical examination of a large portion of the Mexican plants led to much fuller

synonymy and references to the existing literature in the second and succeeding

volumes than is given in the first, and we are fully justified in saying that the quality.

of the work has improved in consequence.

Although an immense amount of time has been spent in looking up published

species not represented in the Kew Herbarium by authenticated specimens, some,

doubtless, have been overlooked; but a few omissions are of little consequence. Had

every name referring to a Mexican plant been taken up, the result would have been

literary completeness, it is true, yet nothing more. Moreover, it would be mere

affectation to apologize for shortcomings of this kind in a work professedly little more

than a skeleton from the standpoint of a systematist. As explained in the Appendix,

upwards of a thousand nominal species are left out of consideration in the geographical

tables, because it is believed that their retention would swell the proportion of the

endemic element beyond what it really is.

PREFACE. v

The writer now has the great pleasure of recording his obligations and thanks to

Mr. W. H. Fitch, the artist, and to his colleagues at Kew, especially to Professor D.

Oliver, whose unrivalled knowledge of flowering plants is always at the service of

others. Mr. J. G. Baker is almost wholly responsible for the nomenclature and

limitation of the species of vascular cryptogams; but this matter is more fully

explained in the remarks under the various orders.

The writer also feels that he would very much like to be permitted to. mention

that he has experienced the most liberal treatment from the Editors, who have expended

a much larger sum of money (to say nothing of time) on the work than they can

possibly see returned. Under other circumstances much more might be written on

this point.

The coloured Plates were taken from sketches made from the fresh plants by

Mrs. Salvin in Central America in 1873-74.

INTRODUCTION.

AS stated in the Preface, this work was undertaken mainly in the interests of Geogra-

phical Botany; and the distribution of the plants enumerated therein has been tabulated

and discussed in considerable detail in the ‘‘ Appendix ” contained in the fourth volume.

The completion, or approaching completion, of several important works on systematic

botany, dealing with the vegetation of large areas, such as Boissier’s ‘ Flora Orientalis,’

Hooker’s ‘Flora of British India,’ Gray’s ‘Synoptical Flora of North America,’ and

monographs of large Natural Orders, together with recent botanical explorations in

China, Madagascar, the mountains of Tropical Africa, and elsewhere, affords materials

for a wider survey of the distribution of plants than has hitherto been attempted, and

a closer comparison of the primary botanical and zoological regions of the world. To

do this exhaustively would, of course, occupy much time and fill a large book; therefore

only an exposition and rapid review of the principal facts will be attempted here *, and

the inquiry will be limited to flowering plants.

Before approaching the examination of the botanical regions themselves it seems

desirable to produce some further statistics and then endeavour to estimate their

relative value yf.

Throughout this work the classification and generic limits of Bentham and Hooker's

‘Genera Plantarum’ have been followed, and all comparisons are made on the same, or

practically the same, basis. Since the appearance of the first part of the ‘Genera

Plantarum’ in 1862, very numerous new plants have been discovered, including some

extremely singular and anomalous ones, though none probably to which the authors

would have assigned the rank of a new natural order. The number of distinct genera

and species has, however, been largely augmented. Elsewhere { some particulars have

been given of the subsequent additions to the Composite, but it is unnecessary to enter

into similar details respecting all the natural orders. Nevertheless, for purposes of

comparison, it will be convenient to give here some of the statistics and rough approxi-

mations arrived at in the ‘Genera Plantarum’ §.

* The questions discussed in the following pages might more appropriately have been incorporated in the

“ Appendix ;” but this is a further development of the subject suggested by Sir Joseph Hooker after perusing

the analysis of the Flora of Mexico.

+ Following the most approved nomenclature, the primary geographical divisions of the vegetation of

the world are designated “ regions” and the secondary divisions “ subregions.”

At Kew it is the practice to post up all proposed new genera as they are published,

and from a cursory examination of their claims to this rank (in Bentham and Hooker’s

sense) the number of distinct genera now known is about 8000; and, allowing a

proportionate increment of new species, the total may be placed at 100,000. Judging

from the exceedingly large number of new forms in the latest collections from the

Malayan Peninsula, Borneo, New Guinea, and Central China, future explorations will

doubtless considerably increase these totals. Absolutely nothing is known botanically

of immense tracts of the interior of Africa; whilst such comparatively well-explored

countries as Mexico and Central America still continue to yield as much as ten per

cent. of new species in collections made out of the beaten tracks, and in a North-

Mexican collection of about 270 species made by C. G. Pringle in 1887, 20 per cent.

are indicated as new in a catalogue by A. Gray and S. Watson.

The general distribution of the natural orders is given in our fourth volume,

pages 201 to 207. Below are enumerated those natural orders of plants estimated by

Bentham and Hooker to contain 1000 species and upwards :—

Genera. Species. Genera. Species.

+ In some instances Bentham and Hooker indicate the number of species of an order as ranging between

two sums, the lower of which was taken by Mr. Brown. From an independent calculation, based partly on

the higher, and partly on the mean of the two sums given, a total of 96680 species is obtained.

INTRODUCTION. xl

From the foregoing it will be seen that twenty-five, or one eighth, of the natural

orders include much more than half the genera, as well as of the species; and all of

them are very widely dispersed ; sixteen of them extending to the arctic regions.

Twenty natural orders have only from one to three genera and less than ten species,

namely :—

Some of the foregoing orders are quite local, while others have a wider range,

particulars of which are given in the fourth volume, pp. 171-205. There are six

other orders of only one genus each, namely, the American Lacistemacee, com-

prising sixteen described species, and the Australasian Stackhousiacee * of about

twenty species; the widely spread Frankeniacee and Myricacee, and the Old-World

Nepenthacez and Casuarines:: all rather numerous in species.

As another illustration of the Flora of the World, a list of genera numbering 300

species and upwards each is appended, together with their general distribution f.

Totals. . 28 . 12400

These twenty-eight genera contribute 13 per cent. of Bentham and Hooker's estimate

of the total number of species of flowering plants. With regard to the actual numbers

given, some of them, at least, are considerably below what the authors would them-

selves probably distinguish as species. Thus, for instance, Bunge, in a monograph of

the Old-World species of Astragalus, published since the corresponding part of the

‘Genera Plantarum,’ describes 971 species, and he has subsequently increased the

number to upwards of 1000; and there are at least 200 American species. The

estimated number of species of Piper and Peperomia is perhaps in excess of that

actually existing. .

There is one more feature in the world distribution of flowering plants demanding

attention, and that is the wide or peculiar range of certain species, which possess no

special means of dispersion by animals or birds or the elements, and which are most

unlikely to have been aided, intentionally or unintentionally, by man. Such species

are not few in number, but a sample of them will be sufficient as an illustration of

distribution, and a selection may be made from those inhabiting Britain. Sir Joseph

Hooker has discussed this phenomenon with greater fulness than we have space to do

in this place *.

It is not intended to discuss the various means by which the above-named plants

may have been thus dispersed—whether by migrations or natural agencies, inasmuch as

this has already been done as exhaustively, perhaps, as the data permit.

The following table, extracted from an abstract of a paper by Mr. T. Comber on the

world distribution of British flowering plants *, is a further illustration of the relatively

wide distribution of what Sir Joseph Hooker has designated the Scandinavian Flora. It

is a summary of the distribution of the vascular plants regarded as indigenous to

Britain, divided into four climatal classes, according to the latitude or altitude they

inhabit. The first column contains the names of these classes, which are sufficiently

descriptive to be intelligible; the sixth column the total number of each class, and the

intermediate columns the number of species extending to the countries or areas named.

appear in two categories; and it should be explained that a considerable number of

the plants indicated in the second column as having only European extensions actually

reach North Africa. The term “ universal” is applied to those plants which spread

into all three of the northern continents ; and it also includes the cosmopolitan species.

With regard to the “ southern universal ” the majority extend into the tropics; and of

the “temperate universal ” sixteen species recur (in the southern hemisphere) in America

only, ten in Africa only, and thirteen in Australia and New Zealand only; while

fifty-six are more widely spread in south temperate regions. Though the foregoing

numbers can only be accepted as approximate, they convey a good idea of the wide

distribution of the British Phanerogamic Flora, which does not contain a single well-

marked endemic species. |

STATISTICAL COMPARISON OF THE FLORAS OF LARGE AND WIDELY SEPARATED AREAS.

In the ‘ Appendix’ (vol. iv. pp. 202-207) comparisons are made between the Floras

of Mexico and Australia, and the relative positions of the natural orders shown,

according to their predominance in species. No very special meaning or importance is _

attached to such comparisons ; yet they are exceedingly interesting, and teach something

beyond mere numbers of species, especially to persons possessing a practical knowledge

of the nature, size, duration, &c. of the plants constituting the various natural orders.

It is thought, therefore, that an extension of such comparisons to a third area, that of

British India, may be welcome. There are many similarities as well as diversities in

the American and Asiatic areas: similarities in the altitudinal and latitudinal ranges

of the two countries, and in‘a less degree in their climatal conditions; diversities in

the direction of the principal mountain-chains, and consequently of the aspects of the

slopes or exposures, and diversities in the land-connections, drainage, and coast-line.

It would unduly lengthen this sketch to enter into further particulars on these -points,

therefore a tabular view of the composition of the Indian Flora compared with those

of Australia and Mexico* may follow here. This table was drawn up, with the

assistance of Sir Joseph Hooker, from his ‘ Flora of British India’ as far as published,

and from the Kew Herbarium and recent monographs, such as Engler’s ‘ Aracee’ and

Baker’s various papers on petaloid monocotyledons. ‘The writer, however, is entirely

responsible for the numbers of species of the genera of Orchidee, Scitaminee, Gramineae,

and some smaller orders, whilst Mr. C. B. Clarke obligingly furnished the numbers of

the Cyperacee f. At Mr. Salvin’s suggestion a column showing the position of the

natural orders in the Flora of the World has since been added.

* For shortness Mexico is employed here and elsewhere instead of Mexico and Central America.

+ Owing to some mistakes in the figures, chiefly in the number of species of Quercus, discovered after the

table was compiled, the percentages were calculated from a total of 13,647 instead of 13,700. The orders

affected have been transferred to their proper positions, but it was not thought desirable to make any other

alterations.

The mean proportions of the five countries are 79:97 dicotyledons and 20-03 per cent.

monocotyledons, against 81°29 and 18°71 for the whole world, showing that the nume-

rical proportions do not greatly vary for large areas, no matter how distant they are,

nor how dissimilar is their vegetation as a whole; yet it is hardly necessary to add that

very different proportions exist in smaller areas. Generally speaking, the drier the

region the smaller the proportion of monocotyledons, and the greater the proportion of

them bulbous plants. Maximowicz § in an analysis of the vegetation of different parts

of Central and Eastern Asia gives the percentage of monocotyledons in the Phanerogamia

as 14:1 in Tangout, or Northern Tibet, and 26-1 in Japan. But, as already hinted,

figures of this kind convey no very definite information, inasmuch as they embody no

idea of individual development, as a species of palm, bamboo, or banana of the tropics

counts no more than a snowdrop, daffodil, or small grass of the temperate regions.

Alphonse De Candolle ||, who presents very numerous statistics of the proportions of

monocotyledons and dicotyledons in small areas, strongly insists on this point. It should

be borne in mind that all statistical analyses of floras are to a great extent illusory, and

can only be properly appreciated after a careful consideration of the composition of the

elements. This fact is illustrated in the following somewhat detailed examination of

the preceding table. —

One thing brought into great prominence by this table is the large number of

xx INTRODUCTION.

natural orders represented in each of the areas under consideration, especially in India,

where there are 86 per cent. of the orders retained by Bentham and Hooker. This

is not put forward as something new, though it will be new to most people, but it

comes out more strongly than might have been anticipated. It should be mentioned,

too, that British India covers only a portion of one of the primary botanical regions,

though, on the other hand, the upper belt of vegetation of the Himalayas belongs to

the northern region. Let us pursue the ordinal distribution a little further, premising

that the reader will remember that important particulars not given here may be found

in the Appendix.

The phenomena of ordinal distribution as set forth in the six preceding tables

demand a few words of explanation. Respecting the first table, it is remarkable how

little it contains ; how few important orders, considered either as to their extent or

structural peculiarities, in relation to the land-area of the rest of the world. The

* Specimens of the South-African Dischisma capitatum, Choisy, were collected by Drummond in West

Australia, but Bentham regarded the species as ‘ most likely introduced,’ and Mueller treats it as an

undoubted alien.

Xxii INTRODUCTION.

succeeding tables afford further information on the distribution of most of these orders.

Those printed in italics are represented in Asia; some of them by solitary outliers;

others, the Calycanthaceze for example, as fully as elsewhere, and these may yet be

found in the mountains of Northern India.

Not less remarkable is the small number of orders in the second table, especially

in relation to the vegetation as a whole, of the two hemispheres*. With regard to

the third, future explorations may probably reduce the total by about half a dozen

orders, though not more. The fourth and fifth tables deal in different ways with

orders included in the first; the fifth bringing also into great prominence the fact

that there is exceedingly little ordinal peculiarity in the rest of the world, including

the vast African region. The sixth table contains only one important natural order,

namely the Dipterocarpee, which are known to extend to New Guinea, and some may

possibly exist in tropical Australia. Altogether, twenty-six of the Indian orders are

not found in Australia, and nineteen of them are not found in Mexico.

Natural Orders not known to extend beyond America.

Canellacez. Leitneriez.

Vochysiacez. Lacistemacee.

Calyceracez. Mayacez.

Columelliacez. Cyclanthacez.

The Galapagos islands are regarded as belonging to the American region. Besides

the foregoing orders, which appear to be absolutely confined to America, there are the

Humiriacez, which are American with one exception in W. Africa; the Turneraces

are represented by a few species in the African region ; the monotypic genus Kissenia

is the only member of the Loasacez found out of America; and, with the exception of

the genus Rhipsalis, the Cactacee are wholly American. Hence it will be seen that

between what is wanting and what is peculiar to America in natural orders, the balance

is somewhat in favour of the latter. This completes the review of the leading features

in the distribution of the natural orders.

Something might be added here on the relative visible and spacious position occupied

by the dominating orders in the different Floras; but as it is proposed dealing briefly

with this part of the subject further on, some illustrations of generic and specific

distribution are given first.

GENERIC AND SPEcIFIC COMPOSITION OF THE FLORAS OF DIFFERENT AREAS.

At page xix are given the relative numbers of orders, genera, and species in the Floras

of India, Mexico, North America, and Australia ; and although no special significance

* See vol. iv. pp. 202-207,

INTRODUCTION. Xxill

is to be attached to the fact, it is remarkable and noteworthy, as a matter of figures, what

a close approach there is to uniformity in the proportions in each of these four

dissimilar and distant areas. Thus :—

Average number of Genera Average number of Species

to an Order. to a Genus.

India. . . . . . . . 18:0 6:0

Mexico. . .... . 110 «64

N. America .. . ... 96 6°2

Australia . . . .. . 87 6°4

The proportions for the whole world, calculated from the numbers of the ‘ Genera

Plantarum,’ are 37:50 genera to an order, and 12°65 species to a genus; from which it

appears that there is, approximately, half of the average number of species of a genus,

and a third to less than a quarter of the average number of the genera of an order in

each of these large areas. Taking a portion of the Cape Flora, the average number of

species to a genus is 6°6*; therefore between six and seven to one is probably the

highest, or nearly the highest, average in large areas. Turning to other areas, the

proportion of species is found to be much lower, and in certain insular Floras the

genera are nearly as numerous as the species. In China the Polypetalous orders f

yield about three species to a genus; and the proportions are nearly the same in the

whole vascular plants of New Zealand, as well as in the Sandwich Islands. In Japan,

the proportions are as 2°6 to 1; and of the probably endemic plants of St. Helena they

are less than 1°4 to 1. .

Such are the averages, which, as has been shown (vol. iv. pp. 212-217), are made up

to a great extent by genera numerous in species and genera of one species each. In

the Mexican Flora, for example, eighty-five genera contribute 4760 species, or 39 per

cent. of the total, whilst other 660 genera are represented by only one species each,

upwards of one third of them being absolutely monotypic. The composition of all

large Floras, in which there is a high percentage of species to a genus, is similar ; whereas

in the Chinese and Japanese Floras there are exceedingly few very large genera, and at —

the same time a smaller proportion of monotypic genera. We have not counted the

monotypic genera of the Indian Flora, but the proportions are probably very nearly

the same as in the Mexican Flora. As mentioned elsewhere, Mueller { states that

there are 550 genera in Australia represented by only one species. With regard to

large genera in the Indian Flora there are only seven of 100 species and upwards each,

against ten in Mexico and four § in Australia ; and there is nothing in either India or

From these figures it appears that about 4°8 per cent. of the total number of genera

INTRODUCTION. XXV

of flowering plants in the Flora of India yield nearly 37 per cent. of the total number of

species. In Mexico 4:6 per cent. of the genera comprise 39 per cent. of the species; and

in Australia the amounts are about 4°64 and 37 per cent. Itis unnecessary to add that

most of the above genera are widely spread, and many of them common to the New

World.

Genera common to the widely separated areas of India and Mesico.

From the relations of the average number of species to a genus in the areas under

consideration to the average for the whole world, it follows that the average area of a

genus must be at least double one of these areas. But there is no necessary relation

between the area a genus covers and the number of species it contains, though, speaking

generally, monotypes have a restricted area. Indeed, if we exclude aquatic and sea-

coast plants, and such as have probably been dispersed through human agency, it is

difficult to multiply instances of monotypes with a large area. The curious Cressa cretica

may be cited as a possible exception *. On the other hand, the species of some large

genera are concentrated in one region, as Eucalyptus in Australia, and Miconia in

America. |

Disregarding exceptions, it may be stated that the genera and species of the northern

Floras have the widest range; those of the tropics an intermediate one, and those

characteristic of the southern Floras, excluding that of the coldest zone, the most

restricted range. Probably not less than 75 per cent. of the genera of the Flora of

Eastern America, north of Mexico, are represented in the Old World, for in some

statistics on the vegetation of the north-eastern part of the United States, drawn up

by the late Dr. A. Gray more than thirty years ago}, it is shown that 63 per cent. of

the then known genera were common to America and Europe, or America and eastern

temperate Asia. Since that date many others have proved to be common to America

and the Old World, and the rich collections made by Dr. A. Henry within the last three

years in Hupeh, one of the central provinces of China, have added several conspicuous

genera to the number.

A careful comparison of the generic composition of the Mexican and Indian Floras

reveals the fact that 581, or 25°58 per cent., of the Indian genera are likewise repre-

sented in Mexico. Our own table (vol. iv. pp. 207, 208) shows that more than a third

of the Mexican genera are widely dispersed, that is to say, they occur as well in two or

more of the large divisions of the Old World; and only 11 per cent. are endemic.

Engler} finds that only about an eighth of the tropical dicotyledonous genera inhabit

both America and some part or parts of the Old World. On the other hand, 30-5

per cent. of the Australian genera and 35:5 per cent. of the South-African are endemic.

XXvi . INTRODUCTION.

Comparing the number of endemic species of the Indian Flora with that of other

parts of the world, it is somewhat surprising to discover that it is less than 2 per cent.

below the Mexican, and not far below that of the Australian; being no less than

68°67 per cent. But such statistics embrace only one class of facts, the value of which

will be briefly discussed in connection with the delimitation of the primary botanical

regions.

ON THE DISTRIBUTION OF SOME OF THE LARGEST NATURAL ORDERS.

Attention has already been directed to the illusory nature of mere statistical com-

parisons of the vegetation of different regions. In many Floras the orders richest in

species are not those which give character to the scenery, or constitute the bulk of the

vegetation ; and the genera are sometimes less numerous and less diversified than those

of many concomitant orders less numerous in species. This is pre-eminently the

case with the orchids in India. Many of the species are exceedingly rare and local ;

many are small plants with inconspicuous flowers; and the comparatively small number

of common species having large conspicuous flowers, lend colour to the vegetation

rather than give character to it, and this only in certain districts. Here and there

in the mountains, as we learn from travellers and residents, the rocks are clothed

with orchids, and when they are in full flower form a conspicuous feature in the land-

scape. In South Mexico and Central America orchids, though third in order of

predominance, pervade the whole country to a greater extent; yet here, as elsewhere,

the existence of the preponderating epiphytic species depends largely on the arboreous

vegetation. In Northern and Eastern India and Malaya, as in Mexico, orchids are

specially abundant in the intermediate or oak region, and the numerous species of

oak constitute one of the principal features in the vegetation. Lower down in the

more tropical parts of India arboreous Leguminose, Euphorbiacee, figs, laurels,

Dipterocarpee, Anonacee, together with Rubiacee, Acanthacee, Composite, Scita-

mine, Aroidee, &c., constitute the bulk of the vegetation—some of these orders,

their genera, or even species predominating in one district, some in another; but each

or any of them entering more fully into the composition of the vegetation than orchids.

Palms form a conspicuous feature on the coast and plains of India, where the more

or less cultivated coco-nut, the palmyra (Borassus), and Phenix sylvestris abound and

cover large tracts; but there is little variety in the prominent species; and the order

occupies the thirtieth position only by reason of the large number of species of rattan

(Calamus) that inhabit the dense forests, and render them almost impenetrable.

Nowhere is there anything resembling the highly diversified palm-groves of the

Amazon region.

In Mexico the Composite outnumber the order next in sequence by upwards of 100

genera and 500 species, and although few of them exceed the stature of shrubs, they

grow in almost every variety of situation; are often excessively numerous individually ;

INTRODUCTION. XXVil

constitute a prominent part of the vegetation, and specially characterize the dry districts.

Such highly characteristic Mexican orders as the Cactacee, Labiate (Salvia), Amaryl-

lidaceee (Agave and Furcrwa), Aroidee (Anthurium, Philodendron), and Liliacez

(Yucca and Dasylirion) are as numerous in species as they are prominent in the

scenery

Turning to the Australian flora we find almost complete agreement between the

numerical strength of the natural orders in species, and their degrees of domination

in the composition of the vegetation. The Leguminose stand at the head with

upwards of a thousand species, including the highly characteristic phyllodineous

Acacias, numbering three hundred species, and prominently pervading the whole

country. Next come the Myrtacee, to which belong Eucalyptus (120 species),

Melaleuca (100 species), Verticordia, Calycothriz,and Darwinia, with thirty-five species

each; followed by the Proteacee (Grevillea, Hakea, Banksia), Composite (Olearia,

Helichrysum), Cyperacee, Graminez, Orchidew, Epacridee, Euphorbiacez, Goodeniacee,

and Rutacez. .

Similar conditions obtain in the Cape Flora, and a person possessing a fair knowledge

of plants can, from statistics alone, form some conception of the nature and composition

of the vegetation.

Before leaving this part of the subject it may not be amiss to mention the fact that

the vegetation of different districts of a country may present more striking diversities

and much more abrupt transitions than does the whole flora of one country as compared

with that of another. Within a few yards the whole character of the vegetation

often changes, owing to differences in the substratum of the soil and other causes.

Mr. Salvin was particularly impressed by this fact in Guatemala, where, in travelling,

you often literally step from an oak-forest into a pine-forest, with the carpet and canopy

(epiphytes, &c.) of vegetation equally as different in character as are the pines and

oaks themselves.

Tre Primary BoranicaL REGIONS OF THE WORLD CONSIDERED IN THEIR

RELATIONS TO THE: ZOOLOGICAL REGIONS.

Very various are the divisions and subdivisions of the world proposed by different

botanists and zoologists who have written on the geographical distribution of plants

and animals; but the comparisons instituted here will be with the zoological regions

originally defined by Dr. Sclater *, and subsequently adopted, with slight modifications,

by other eminent zoologists, notably by Mr. Wallace in his very elaborate treatise on

the present distribution of animals, more especially of the mammals. For convenience,

his table of regions t+ and subregions is reproduced here, as it is more intelligible than

Before explaining my own ideas on the primary phyto-geographical regions of the

world, it may be of interest to give in outline the two latest attempts to define them,

especially as one of these has been published in the form of a very elaborate atlas for

educational purposes.

In 1882 Dr. Engler * grouped the botanical regions of the earth,

on the assumption that there existed in the Tertiary period four fundamental elements

of the present vegetation, namely—the “ Arctic Tertiary ” element, the “ Paleotropical ”

element, the “Neotropical” element, and the ‘Old Oceanic” element, which he

der tropischen Gebiete, pp. 326-347.

INTRODUCTION. XX1X

briefly defines, and then proceeds to divide the vegetation of the earth into “ kingdoms,

regions, provinces, zones, and districts.” To give the whole of his subdivisions would

occupy more space than can be afforded, and carry us beyond what is necessary in this

discussion. His primary divisions are four, corresponding to his four Tertiary elements.

These are :—the northern extratropical floral kingdom, the paleotropical floral kingdom,

the South-American floral kingdom, and the old oceanic floral kingdom. In conformity

with English usage we will call his primary divisions regions and the secondary ones

subregions ; and where we have occasion to refer to the smaller divisions, the names

given above will be employed. Engler’s secondary divisions are as follows :—

1. NoRTHERN EXTRATROPICAL REGION.

SuBREGIONS: 1. Arctic; 2. Subarctic or Conifer; 3. Central Asiatic; 4. Mediter-

ranean; 5. Mandshurian and Japanese; 6. North-American Pacific; 7. North-Ame-

rican Atlantic.

2. PaLZoTRoPIC REGION.

SuBREGIONS: 1. West-African forest ; 2. African and Arabian desert; 3. Malagassy ;

4. Western Indian; 5. Tropical Himalayan; 6. East-Asiatic; 7. Malayan; 8. Arau-

caria; 9. Polynesian ; 10. Sandwich Island.

3. SouTtH-AMERICAN REGION.

Susreeions: 1. Mexican Highlands; 2. Tropical American; 3. Andine; 4. Gala-

pagos ; 5. Juan Fernandez.

4, Otp Ocranic REGION.

Suprecions: 1. Antarctic forest of South America ; 2. New-Zealand; 3. Australian; |

4. Kerguelen; 5. Amsterdam Island; 6. Cape; 7. Tristan d’Acunha; 8. St. Helena.

The ternary subdivisions or provinces of the Northern Extratropical Region of the

above scheme are about forty; many of them are divided into several zones, and some

of them again into numerous districts. Subdivision is, for obvious reasons, not carried

so far in the three other regions.

I have already put on record * my objections to that part of Dr. Engler’s scheme

relating to oceanic islands and the “antarctic” Flora; but I have now to deal

with it as a whole. Theoretically there may be much to justify his regions; yet it

seems to me that any attempt at division based partly upon assumed, or even proved,

anterior conditions, and partly on present conditions, is unsatisfactory and confusing.

On this point Wallace says + :—‘ Our object is to represent as nearly as possible the

* Botany of the ‘ Challenger’ Expedition, i. Introduction, p, 50.

XXX INTRODUCTION.

main features of the distribution of existing animals, not those of any or all past

geological epochs. Should we ever obtain sufficient information as to the geography

and biology of the earth in past epochs, we might indeed determine approximately what

were the Pliocene, Miocene, or Eocene zoological regions; but any attempt to exhibit

all these in combination with those of our own period must lead to confusion.” This

objection applies with equal force to any botanical division; and as a critical exami-

nation of Engler’s scheme would involve the discussion of questions beyond the scope

of the present inquiry, it is sufficient for the purpose to have brought it under notice,

though it should be added that it is full of valuable matter, and has been largely

utilized in the present work. |

The other scheme referred to above is by Dr. Drude. It was originally published

in 1884 *, and again in 1887 as an independent work}. As explained in the title

given below, this is a representation of the present conditions of the distribution of

plants; hence it has a greater demand on our attention. Drude divides the world into

fourteen “ floral kingdoms,” namely—(1) Northern, (2) Central Asian, (3) Mediterranean,

(4) East Asian, (5) Middle North American, (6) Tropical African, (7) East African

Islands, (8) Indian, (9) Tropical American, (10) Cape, (11) Australian, (12) New

Zealand, (13) Andine, (14) Antarctic. Most of these regions are subdivided, and the

overlapping of the elements of different regions is indicated by lines and dots.

As Drude himself remarks, we are all striving and devising with the same aim in

view, and we arrive by different ways to much the same conclusions. He claims that

he obtains practically the same results as Engler, but by different methods; that

Engler’s scheme is, after all, based essentially on present conditions; and says that

there is far more difference in the arguments of the writers on phytogeography than

there is in their deductions and cartographical illustrations. This is doubtless true

to a certain extent, because there are certain facts which no student can overlook or

disregard ; yet it is none the less true that one begins with four and the other with

fourteen regions, and therefore there must be a wide difference in their value and

extent.

Engler’s scheme, based upon a small number of primary regions, commends itself

because these are much more nearly of equal importance than are Drude’s; but his

old oceanic region is altogether inadmissible from the standpoint here taken, involving,

as It does, the relegation of the Northern Island of New Zealand to one of his primary

divisions and the Southern to another. |

A small number of primary divisions undoubtedly offers the least difficult basis for

further division. Equivalent regions and subregions it is impossible to define, because -

INTRODUCTION. XXxi

they no more exist in nature than do absolute differential characters between many

natural orders or genera of plants; but Drude has too many and unnecessarily unequal

regions. Several of them correspond, or very nearly so, to the secondary divisions of

other writers, and are not unnatural in this sense; yet we do not agree with the author

in raising them to primary rank. On the other hand, his Indian region embraces

tropical Asia, the whole of the Pacific Islands, from New Caledonia to the Sandwich

Islands, and a large area of North Australia. It is unnecessary to dwell upon the

great disparity of this region as compared with his East-African Islands region, or his

New Zealand region of the same rank.

With regard to the Flora of the Sandwich Islands, it is so highly specialized, and

its affinities so complex, that it cannot be included in any primary region without

the question arising whether it might not with equal propriety have been included in

another, as will hereafter be shown.

The Flora of North Australia undoubtedly contains a large tropical element consisting

of species, many endemic, of Asiatic genera, or genera of wider range; but the elimi-

nation of such species as are common sea-shore plants throughout the eastern tropical

region would considerably reduce this element. It is equally true that some of the

orders and tribes specially characteristic of the Australian Flora are almost entirely

wanting, such as the Epacridee, Rhamnaceew, Myoporinee, Boroniee, the Podalyries,

and some others; but are these two conditions sufficiently developed to justify separation

in a primary division and annexation to the eastern tropical region? Drude appears

to have separated it because it is tropical. Wherever the boundaries are drawn there

will be overlapping of different elements to some extent, and a more natural boundary

in this region is further north. Even if in the north-eastern coast district the com-—

position of the vegetation is more Asiatic in character, it is not so in the north-west.

Whatever the amount of infusion of Asiatic types may be in North Australia, and

whatever groups are wanting or rare, the highly characteristic Australian gum-trees

(Eucalyptus) and the phyllodineous Acacias are represented respectively by twenty-five

and sixty-seven species ; Proteacez by about thirty-five species; Stylidiew and Goode-

niaceee combined by upwards of fifty species; Amarantaceee by nearly sixty species;

capsular Myrtacee, exclusive of Eucalyptus, by about thirty species; and many

characteristic Australian genera, such as Dodonea and Stackhousia, are also present,

though numerically few.

There seems even less reason for including New Caledonia in the Indian region,

for although the Rubiacez and sarcocarpous Myrtacez appear to be the dominating

groups, yet the vegetation generally is more Australian than tropical Asiatic in

character. As Baron Mueller observes *, New Caledonia is the only country outside

of Australia where capsular Myrtacee are largely developed, though they include

* A Lecture on the Flora of Australia, 1882, p. 16.

xxxii INTRODUCTION.

no species of Eucalyptus. Only fragments of the New Caledonian flora have been

published, but from a rough manuscript list of New Caledonian plants contained in

the Paris Herbarium, compiled by Sir Joseph Hooker twenty-five years ago, the

Australasian character of the vegetation is evident. Examples are offered by such

genera as Cordyline *, Dianella, Araucaria, Frenela, Dacrydium, Hedycarya, Casuarina

(five species), Exocarpus, Grevillea, Cenarrhenes, Knightia, Stenocarpus, Myoporum

(four species), Leucopogon (twelve species), Dracophyllum (ten species), Hibbertia

(fifteen species), Pittosporum (twenty-five species), and Boronia (eighteen species).

It is noteworthy that the phanerogamic flora of New Caledonia, unlike that of New

Zealand, is exceedingly rich in species, yet, as in New Zealand, many characteristic

Australian groups of plants are wholly wanting.

The flora of New Zealand has been so exhaustively discussed by Hooker, Wallace,

Engler, and others, that it is inexplicable why Drude should have raised it to the rank

of a primary region. It is remarkable for its poverty and the total absence of many of

the most characteristic Australian types; yet, apart from the extraordinary development

of such widely spread genera as Ranunculus, Epilobium, and Veronica, the flora is so

essentially Australian that it is difficult to understand why there should be any hesi-

tation in treating it as a subregion of the Australasian flora; especially by an author

who would include the Sandwich Islands in the Indian region.

As far as the Flora of Madagascar and adjacent islands is concerned, the reasons for

regarding it as a primary region are more intelligible; and some zoologists have pro-

posed the same thing ; but recent explorations prove that it should rank asa subregion

of Africa. Although rich in endemic genera and species, it is not relatively more

so probably than the Malay Archipelago or Ceylon in Asia, It is true that the small

order Chlenaces is apparently peculiar to the island, for there is little doubt that the

two members of this order recorded from Mozambique were collected by Forbes on

the Madagascar side of the channel of that name. Briefly, the forest flora of Mada-

gascar.is. closely related to that of tropical Africa, while South-African forms reappear

in the hill flora; and it exhibits still closer affinities with Mauritius, Bourbon, and the

neighbouring islands.

Sufficient has been advanced perhaps to show that Drude’s divisions are not always

the best that could be devised, and that his primary divisions are too numerous, OY,

from another standpoint, not numerous enough to attain the nearest approach to

equality.

Ten years ago Mr, Thiselton Dyer { drew up a concise and pregnant sketch of the

geographical distribution of plants, in which he deals with both present and past con-

ditions, more especially in relation to the theory of a general southward migration.

He groups the Floras of the world into northern, tropical, and southern, and enters

into particulars of the characters, relationships, connections, and dissimilarities of

these groups. Drude groups his primary divisions in the same manner *; and this is

perhaps the most philosophical method of dealing with them, though, on account of

the greater differentiation the southern Floras present, it is preferable to consider

them separately—that is to say to give the Australian, African, and South-American

regions the same rank as the great northern region, and treat their tropical and

temperate parts as subregions of so many regions, rather than subregions of a south

temperate and a tropical zone respectively. Too close an adherence to climatal

primary regions leads to unnatural combinations, as has been pointed out in regard to

Drude’s Indian region. But before entering more fully into the limits of the primary

botanical regions, Wallace’s zoological regions will be briefly discussed in relation to

the distribution of plants.

CoMPARISON OF THE ZOOLOGICAL WITH THE BOTANICAL REGIONS.

Wallace based his zoological divisions (as tabulated, page xxviii) on the present

distribution of mammals, having, after years of study and research, arrived at the con-

viction that this class furnished the best foundation for the purpose. He also found

that the distribution of birds and other groups harmonized sufficiently with such a

division, and any anomalies or divergences in their distribution were capable of

explanation by a study of the exceptional means of dispersal and conditions of

existence. Still he is careful to emphasize the fact that any system of division must

necessarily be more or less arbitrary and artificial, and not equally applicable to all

classes of animals. Such mammals as the bats, which fly, and the oceanic mammals,

which swim, possess exceptional means of dispersal, and therefore they are not taken

into consideration. These exceptions and many other phenomena of distribution in

the animal kingdom are paralleled in the vegetable kingdom, but no intelligible system

of botanical division could be based on the distribution of any one group of plants

less comprehensive than the Phanerogamia, because the large orders, such as the Com-

posites or Leguminose, comprise plants of every size, habit, and duration, inhabiting

every kind of situation. As an illustration of the wide dispersal of a very large pro-

portion of the natural orders of plants, the reader may be referred back to the

analysis of the flora of British India, pp. xv-xxii. Generally speaking, the smaller a

Flora the larger the proportions of orders and genera to the total number of species t.

XxXiv INTRODUCTION.

Notwithstanding the different and often greater means of dispersal possessed by plants,

it is surprising how very similar are the broad features of the distribution of plants and

animals. Doubtless this is owing in part to interdependence; and extensions of area

of members of the two kingdoms have probably often been contemporaneous. Still,

there are important divergences, and the primary regions of plants and animals cannot

always be held as conterminous; assuming, of course, that Wallace has adopted the

most natural divisions that could be found. This is most strikingly exemplified in the

northern floras. Wallace was able to keep separate the eastern and western hemispheres,

even in the north; and his palearctic and nearctic regions he defends against the opinion

of Huxley *, the endemic element being nearly equal in the two. On the merits of the

question of one or two primary northern zoological regions it is not proposed to enter ;

but such a division cannot well be sustained in the vegetable kingdom, the alternative

being more than two. Dr. Asa Gray long ago f pointed out the intimate relationships

existing between the floras of Japan and North America, especially eastern North

America: and the rich collections from Central China received at Kew within the last

two years have added considerably to the number of genera, and almost identical

species, common to Eastern Asia and Eastern America. Many of these extend to the

mountains of North India, and a very few farther westward; but the affinities of the

Floras of Eastern Asia and Eastern America are vastly greater than either exhibits

with that of Europe. It is only in the higher latitude of North Corea and Mandshuria

and northward that the vegetation bears a strong likeness to the European; but even

there the relative proportion of woody plants is much higher than in Europe ~. How-

ever, it seems clear that the whole north temperate and arctic flora is better considered

as forming one primary botanical region, with extensions, or remains of extensions,

through the mountain-chains to the Australasian Alps, Tierra del Fuego, and the.

mountains of Tropical Africa, with only very faint traces in South Africa §.

The alternative of more than two primary northern botanical regions seems quite

inadmissible ; and this is tbe opinion of Engler, who has also specially examined the

paleontological evidence, which proves that many of the genera of E. Asia and Eastern

N. America formerly existed in Europe. If more than one primary northern region

be admitted, we must, like Drude, recognize five or six; and, after all, there are no

Australasia (Australia and New Guinea to Celebes and the Philippines); and 4. New Zealand.

sharper contrasts in the vegetation of different areas of this large region than there are

in the Indian, the Australian, or anv of the southern regions. ‘The poverty in genera

and species of the woody element of the European and West-American Floras and its

extreme richness in the Floras of China and Japan and Eastern N. America are well

known; but with very few exceptions the genera of the former Floras are represented

in the latter. As Gray remarks:—“ All round the world in our zone the woods

contain Pines and Firs and Larches, Cypresses and Junipers, Oaks and Birches, Willows

and Poplars, Maples and Ashes, and the like” *. The distribution of many of the

genera of herbaceous plants of the poorer Floras is even wider. Thus, in California,

where there is an enormous development of peculiar genera of some orders, the

Ranunculacee are represented by thirteen genera, whereof eleven are also British, and

one other is European, and the solitary one remaining is anomalous and endemic, and

has been referred to various natural orders. The Orchidacee, again, are represented

by ten genera, eight of which are British. Calypso borealis is a native of Northern

Europe and Siberia, and the monotypic Aplectrum ranges across the continent to the

Atlantic, being the only one restricted to America.

The subregions of Wallace’s palearctic and nearctic zoological regions are perhaps

less in harmony with botanical subregions than those of any other part of the world.

His Mediterranean and Mandshurian subregions in the Old World, and his Californian,

Rocky Mountains, and Eastern United States in the New World, are, however, substan-

tially identical with botanical subregions. It does not come within the scope of this

sketch to examine and discuss all these subregions, but a few remarks follow on the

Chinese and North-Mexican Floras, which have recently been more fully investigated.

In a lecture delivered before the Royal Institution of Great Britain in 1878, and after-

wards published, Sir Joseph Hooker explains the main features of the distribution of

the Flora of North America, and Professor C. S. Sargent has exhaustively described and

elaborately illustrated cartographically the distribution of the arboreous element f;

and Mr. C.J. Maximowicz has made a valuable contribution to the botanical geography

of Central Asia in a paper which has already been referred tof. In these and various

other more generally known publications much new light is thrown on the nature,

composition, and distribution of the vegetation of the countries under consideration.

With regard to Wallace’s Mandshurian or Japanese subregion, as already hinted, a

corresponding botanical subregion would be differently bounded; its northern limit

barely reaching Peking and its western limit not extending so far, if at all, into

Mongolia. In the present comparatively early stage of an enumeration of Chinese

plants * the data are not forthcoming to describe exactly where this subregion should

be bounded, but it is warm temperate in climate, and characterized by having a very

large woody element, with intimate Himalayan and Eastern North-American connec-

tions. Rarity of annual plants is also strongly marked. Collections received since the

publication of the parts of the ‘Index’ issued have very largely augmented the num-

bers of genera and species, especially of the earlier orders, which were elaborated before

even the first collection came to hand, Therefore data taken from it alone are im-

perfect beyond even what is known of the flora. To give some idea of the large

number of species concentrated in a small area, it may be mentioned that Dr. A. Henry

has collected upwards of a thousand species of flowering plants within a short distance

of Ichang, and at a very moderate estimate ten per cent. of them were previously

unknown.

A rough analysis of the Polypetale enumerated in the ‘Index’ gives a total, exclud-

ing cultivated and doubtful ones, of 1514 species belonging to 476 genera and sixty-

six (out of a total of eighty-five) natural orders. Fourteen of the genera and 626 (or

41:3 per cent.) of the species are apparently endemic, but these figures do not represent

the true proportions, because all the common plants of the coast districts are

included, and it is very imperfect as far as regards the interior.’ The small number of

species to a genus (about three), half the number found in the larger areas examined,

has already been commented upon. The distribution of the non-endemic species in the

above total, so far as it is known, is as follows :—140 extend to Japan only; 90 to India

only; 27 to India and Japan only ; 273 others are restricted to Asia, inhabiting some

other part or parts than Japan or India, or besides Japan and India; and the remaining

397 (nearly a quarter of the non-endemic) are of wider range.

Other remarkable features in the Chinese Flora are the great latitudinal range of some

of the species, and the high northern localities of some subtropical types, such as

Nelumbo, Euryale, and Cedrela. ‘The same phenomenon is exemplified in the animal

kingdom.

Returning to the New World, it will be seen that Wallace’s Rocky Mountains

subregion embraces the North-Mexican province, as roughly defined in vol. iv. pp. 139

and 306, and the country northward to about 55° Jat., and from about 97° long. west-

ward to the coast range ; thus covering the whole prairie and treeless regions, the central

mountain-range, and Lower California. The corresponding botanical subregion occu-

pies a similar but rather more restricted area, and it is essentially a dry one, falling

into several provinces, one of which, the North-Mexican, is approximately defined

and characterized in the place cited. Dr. Asa Gray and Sir Joseph Hooker seem to

have had some such division in view, though they do not go the length of actually

proposing subdivision beyond the three great floras, namely, the Atlantic, Central, and

Pacific *.

The Californian subregion, which is practically the Sierra-Nevada range and the

narrow strip of country westward of it, is more highly specialized botanically than it

would appear to be zoologically.

The only other of Wallace’s primary zoological regions which differs materially from

the botanical region of the same part of the world is the Australian. This he divides

into four subregions}, all of which, except the ‘ Austro-Malayan,’ are sufficiently

indicated by their names. The Austro-Malayan subregion, of which New Guinea is

the centre, includes the surrounding islands and groups of islands from the Louisiade

Archipelago to Timor, Lombok, Celebes, Gilolo, Admiralty, New Britain, New Ireland,

and the Solomon group. ‘There is no great change in the vegetation such as to justity

the separation of Eastern Malaya and New Guinea from the India region, or Oriental

region, as Wallace names it. Indeed, botanically, it is naturally a subregion of the

Asiatic and not of the Australian region. It is true that a number of Australian types

extend into this subregion, and a few even beyond; but they form a very small per-

centage, and nowhere, so far as is known, do they constitute a feature in the vegetation.

Including all the common sea-shore plants, Miquel’s statistics of the Malayan flora {

show that less than 4:2 per cent. of the Malayan Phanerogamia are also found either

in Australia or Polynesia. However, very little was then known of the vegetation of

New Guinea; but from an examination of Dr. Beccari’s and Baron von Mueller’s consi-

derable subsequent contributions to Papuan botany, it appears that although such

specially characteristic Australian genera as Eucalyptus, Acacia (phyllodineous species),

Styphelia, Stackhousia, Banksia, and Grevillea are represented by one or two species

each, the bulk of the Papuan vegetation is more Asiatic than Australian in character,

and exceedingly rich in peculiar forms.

belonging mainly to the cold temperate region, which have been pretty fully tabulated

by Hooker and Engler, and more recently by the writer). Hucalyptus papwana and

at least one other species inhabit New Guinea||; #. alba, and possibly one other species,

is a native of Timor; and Blume records Eucalyptus deglupta, from the Celebes; but

the genus of this tree is very uncertain, as neither flowers nor fruit were known to the

author. With regard to Eucalyptus multiflora, Rich*, from Mindanao, one of the

Philippine Islands, there is also great doubt as to the genus; and no species of Euca-

lyptus is in any of the older or the large recent collections at Kew from that archi-

‘pelago. Therefore the range of the genus Eucalyptus, so far as it is known with

absolute certainty, is from Tasmania to New Guinea and Timor, and it is essentially a

warm temperate type. Acacia, on the other hand, is almost wholly tropical in its

distribution outside of Australia, and the phyllodineous section, which numbers hard

upon 300 species in Australia, exhibits some much wider and very remarkable exten-

sions. Two or three species of this section inhabit New Caledonia and other islands

of the South Pacific. Acacia richit is a native of the Fiji Islands, and specimens in-

distinguishable from it have been collected in Formosa, separated by forty degrees of

latitude and sixty of longitude, though it may exist and yet be found in some inter-

mediate stations. Another species (A. heterophylla) is indigenous in Mauritius and

Bourbon, and possibly also in Madagascar, and the Sandwich-Island A. koa is so near

it that the late Mr. Bentham was of opinion that it was a form of that speciesf.

The capsular Myrtacez, which are so specially Australian (New Zealand and New

Caledonia) extend to China and the Malayan peninsula, where they are represented by

one, or in some instances two or three species, of the genera Baeckea, Leptospermum,

Tristania, and Melaleuca. Xanthostemon, another genus of the same group, is con-.

fined to Australia and New Caledonia, with the exception of the Philippine Island

A. verdugonianus. Stylidium is perhaps the only strictly Australian type extending

into the heart of India, even to the foot of the Sikkim Himalaya. It is a genus

numbering eighty-five Australian species and three Indian—one of the latter being also

a native of North Australia, a second scarcely more than a variety of it, while the third

is quite distinct. Leucopogon, an Australian Epacrideous genus of nearly 120 species,

extends to the Philippines, yet there are only two species known from the whole Malay

Archipelago. Helicia is apparently the only genus of the Proteacee extending north

of New Guinea into Asia, and this, although represented in Australia, has its greatest

concentration in Malaya and India—ten species being found within the limits of British

India, three of which inhabit Ceylon and the Western Deccan peninsula. One species

is a native of Japan, and one, or more, of South China and Formosa.

Extensions of Australian types into Eastern Polynesia are relatively more numerous

than into Malaya, yet they do not predominate over the other elements of these small

insular floras; and there is such an intermingling of American, Asiatic, and Australian

types in the much more highly-developed Sandwich-Island Flora, that it cannot,

Hawaiian Islands.’ .

INTRODUCTION. XXXIX

as already observed, justly be regarded as appertaining to any one of the great

primary regions of vegetation. The characteristic endemic shrubby Composite* and

Lobeliacee are most nearly related to American forms; Perrottetia is a Mexican and

Colombian genus, and the pomaceous Osteomeles anthyllidifolia is a member of a genus

all the other species of which are Andine. Nama is otherwise restricted to America;

and Hillebrand regards the American Lythrum maritimum, Daucus pusillus, and Aster

divaricatus (== A. evilis) as indigenous. Prominent among the Australian types and

common in all the islands according to Hillebrand are :—Metrosideros polymorpha, an

exceedingly variable tree or shrub scattered throughout Polynesia, eastward to Pitcairn

Island, and Acacia koa, already alluded to. The Australian genera Cyathodes and

Exocarpus are also represented. Cyrtandra, of which there are thirty-two species

endemic in the Sandwich Islands, is more Malayan in character, and many other such

relationships exist, besides other more remote ones in the highest mountain flora,

which includes such forms as Luzula campestris, Rumex, Silene, Ranunculus, Drosera

longifolia, Hydrocotyle interrupta, Fragaria chilensis, Vicia, Vaccinium, Aster, and

Artemisia.

Added to the foregoing elements is a sea-shore element consisting almost exclusively

of species having a very wide range in the Old World; many of them from the eastern

coast of Africa or the Mascarene Islands and India to N. Australia, the Marquesas

Islands and Easter Island. Further, the vegetation of the small and remote coral islands

is entirely of this character. .

Besides the phyllodineous Acacia above alluded to, it has long been known that

there were two or three other noteworthy outlying Australian types in Madagascar ;

but no important addition to these has been made by recent explorations. One or two

species of Hibdertia (Dilleniacez), and two or three of Rulingia (Sterculiacee-Lasio-

petalee); and the genus Adansonia is represented by one endemic species in Mada-

gascar, one in tropical Africa, and one in North Australia. These widely-sundered

areas of distribution of closely-allied forms have given rise to much speculation, and it

is very problematical whether satisfactory paleontological evidence will ever be forth-

coming which will account for the existing distribution of plants.

BoraNIcaL DIVISION OF THE EARTH INTO PRimaRY REGIONS.

From the data adduced in the preceding paragraphs, and numerous more familiar

facts which it is unnecessary to repeat, it is clear that a system of botanical geography

should be based upon a small number of primary regions, similar in many respects to

Sclater and Wallace’s zoological regions. It has been shown where the botanical

regions do not even approximately coincide with the zoological regions, and to some

xl INTRODUCTION.

extent also this has been done for the subregions or secondary divisions; but it is

obviously beyond the scope of the present sketch to pursue this to the end. Yet,

without attempting to define secondary and further divisions of all the primary regions,

it may be possible to give further particulars, which, with what has preceded, shall

convey some general idea of the extensions of the characteristic types of the floras of

these regions. .

Wallace states that nothing like a perfect zoological division of the earth is possible ;

and a perfect botanical division is equally impossible. Therefore the aim is a division

that conveys in itself some notion of the extent of the dispersion of the characteristic

types of each region. As already pointed out, it is obvious that a botanical division

cannot be based on one class of plants, equivalent, if such could be found, to the

Mammalia ; but rather on the general composition of the vegetation, and largely, too,

apart from latitudinal position. On this plan it is not difficult to distinguish five

primary regions; but if this number be exceeded, it must be doubled or trebled with a

less satisfactory result. These five primary regions are :—

1. Northern. 4, South American.

2. African. 5. Australasian.

3. Indian.

These regions are unequal in extent, and the southern divisions are meridional rather

than latitudinal; but the greater degree of differentiation of the vegetation justifies

such a division; and a natural subdivision of the northern region, excluding the arctic

zone, and, perhaps, the coldest arboreal zone, is in the same direction. But these five

_ regions do not include quite all, because, for reasons given, the Sandwich-Island Flora

cannot consistently be included in any one of them; and it would convey a false

impression to rank this comparatively small, though highly peculiar Flora, as a

primary region. Further, there isa remnant of an antarctic Flora which is scattered

all round the hemisphere, constituting the coldest southern zone of vegetation. ‘These

exceptional phanerogamic Floras will be separately discussed.

An alternative primary division, which is more in accord with the writings of many

botanists, and has some practical advantages over the one proposed, may be thus

stated :—

1. Northern Region.

2. Neotropical Region. 3. Paleeotropical Region.

4, Andine Region. 5. Cape Region. 6. Australasian Region.

The anomalous Sandwich-Islands Flora and the fragmentary Antarctic Flora would

be unattached in this, as in the foregoing plan. It is unnecessary to define these

alternative regions, as their denominations are sufficiently descriptive to be intel-

ligible. One of the advantages this division possesses over the one advocated, or rather

the one point in which it radically differs, is the separation of the tropical and temperate

INTRODUCTION. xli

Floras in the primary regions of the southern hemisphere. Elsewhere reasons are

given for treating the Cape and Andine Floras as subregions of more extended areas.

Another important difference is the retention of three south temperate regions against

one north temperate region, which brings out more prominently the greater differen-

tiation of the vegetation of the southern hemisphere. Practically the plan proposed

in this sketch recognizes and deals with these facts, although it does not bring them

into direct contrast.

There is yet another way of treating the subject, one that obviates the necessity for

defined regions and subregions, and one that may be effectively employed for conveying

an idea of the broad features of the distribution of plants: it is by grouping the Floras

into northern, tropical, and southern, as was done by Thiselton Dyer in the lecture

on the geography of plants, which has been referred to before.

Some further justification of the plan here adopted will now be attempted, but it is

not intended to recapitulate well-known facts and traverse familiar ground. The inten-

tion is rather to bring together some facts and data additional to those collected in

the Appendix, or adduced in the preceding paragraphs of the present sketch.

The Northern Region.

This corresponds very closely to Wallace’s Arctic and Palearctic regions combined,

and is adopted for reasons already sufficiently explained; the close relationship of the

Floras of Eastern Asia and of North America, especially eastern, than of either of these

and the European being the principal reason. A rough subdivision of this region

gives eight subregions, namely :—an Arctic, a North and Mid-European and Central

Asian, a Mediterranean, a Chino-Japanese, and in America a continuation of the Arctic,

a boreal, an Atlantic, a Central, and a Pacific subregion. In the Old World we find

that the vegetation of North and Central Europe extends to the extreme east of Asia,

associated there with an endemic element, which increases so much in China, south

of about the fortieth parallel, and in Japan, as to constitute of these countries a distinct

subregion, exceedingly rich in trees and shrubs—richer even than the Atlantic subregion

of North America. The transition from the Chinese Flora to that of a more European

character is very sudden on entering Mandshuria, where probably in some districts fifty

per cent. of the species are European. Maximowicz gives* some interesting figures

illustrating the gradual diminution of the absolute numbers and percentages of species

having a wide area—that is circumpolar, or common to both Europeand Asia. Thus in

Baikal-Dahuria the figures are 747 species, =53°4 per cent. ; in Mongolia 599 species,

46-2 per cent.; in Mandshuria 533 species, =39°6; Peking district, 318 species,

—31:9 per cent.; Japan, 442 species, =16°2 per cent. The percentages of endemic

species in these five areas are respectively 9-4, 8-3, 8:7, 13°3, and 44-0. Maximowicz

comments on the great fall in the percentage of the endemic element passing from

* Bull. Congr. Intern. Bot. Hort. Pétersb. 1884, p. 164.

xhii INTRODUCTION.

Japan to the continent. This is so in the latitude of Peking; but the more southern

province of Hupeh, for instance, would show a much higher percentage than Peking,

and possibly even higher than Japan, inasmuch as the Polypetale of the whole of China

proper, so far as known *, contain 41°34 per cent. of endemic species, and there is no

doubt that the further exploration of the interior provinces will materially raise this

percentage.

Maximowicz very elaborately analyses the affinities of the endemic species in the

areas named, from which it appears that it is only in Japan that there is a considerable

development of endemic species of what he terms the Chinese type. On the other

hand, the “levantine type” is apparent in 13°9 per cent. of the endemic species of

Mongolia. To be brief, Maximowicz sums up this question in words to the effect that

the plants of the plains of Northern and Central Europe constitute the greater part of

the flora eastward to the Pacific coast, if not in identical forms, at least by forms

connected by intermediates with European species f.

It would carry us too far to attempt to give the exact eastern limits of the Mediter-

ranean region in Asia, as it would involve a discussion of the vegetation of the various

provinces of this subregion. The southern limits of the northern region in the Old

World may be indicated approximately as the tropics, varying in different longitudes.

‘It includes the alpine and temperate Flora of the Himalayas, and in Africa it extends

to the Great Atlas f.

The subregions of the northern region in the New World are five, namely :—Arctic,

Boreal, Atlantic, Central, and Pacific, which may be roughly defined. Briefly the

Arctic is a continuation of the same subregion in the Old World; the Boreal is a

westward extension of the hardier elements of the Atlantic subregion, and perhaps

better regarded as a province of it; the southern or Mexican province of the Central

subregion is fully described in the Appendix; and further particulars of the characteristics

of the whole Rocky-Mountain Flora will be found in the joint essay, by the late Dr. A.

Gray and Sir Joseph Hooker, previously cited. The distribution of the North-American

Flora generally is admirably summarized by the latter §, who distinguishes the Sink

country between the Rocky Mountains and the Sierra Nevada as a separate Flora, while

admitting that cacti and yucca attain their maximum development further south in the

same meridian. Professor Sargent describes his northern forest-region as extending

southward to the fiftieth parallel on the Atlantic coast and to the fifty-fourth at the

hundredth meridian ||.

INTRODUCTION. xiii

Allusion has been made to the southward extension of elements of the Flora of the

northern region through the great mountain-ranges to the southern limits of vegetation,

and indications where there are remains of it on the mountains within the tropics and

in south temperate countries. Sir Joseph Hooker's reports on the vegetation of

Clarence Peak, Fernando Po, of the Cameroons mountains, and of Kilima-njaro are

among the most important of the later contributions to the literature of this subject *.

The African Region.

The phytogeographical essays last referred to afford some most interesting details of

the relationships and apparent migrations of the components of the vegetation of the

great African region, which is here understood to comprise the whole of Tropical and

South Africa, Madagascar, Mauritius, Bourbon and the contiguous groups of islets, and

the Cape Verde Islands—Madeira and the Canaries being regarded as a province of

the Mediterranean subregion of the Northern region. Ascension, St. Helena, Tristan

da Cunha, and Amsterdam and St. Paul Islands, though presenting some curious

anomalies in their vegetation, may be regarded as appanages of the African region,

or they might be left unattached to any primary region. Excepting the Composite,

the affinities of the flora of St. Helena are distinctly African ; and Phylica nitida, the

only tree, or even shrub more than a trailer, in the other two groups of islands, is

Mascarene f. Instead of arctic and temperate climates there are in this region tropical

and temperate climates; yet botanically, as well as geographically, this is one of the

most compact of the primary regions, and naturally divides into three subregions,

namely:—Tropical Africa, South Africa, and Madagascar and adjacent islands. Eastern

and Western tropical Asia should only be regarded as provinces of one Flora, as

will presently be demonstrated.

Besides remote connections with the Northern, American, and Australasian regions,

there is a very intimate connection of the African with the Indian region, traceable

from the Cape up the eastern side of the continent to Abyssinia and by way of Socotra,

Southern Arabia, Persia, and Afghanistan to the Panjab and Gangetic plain, and less

distinctly southward into the Deccan peninsula, with a few extensions into the Malayan

peninsula and archipelago ; and notwithstanding the presence in the Madagascar sub-

region of such eminently Asiatic types as Nepenthes, Lagerstremia, and a few others

hitherto not found in continental Africa, it is evident that the interchange between

Africa and Asia is far greater than between Madagascar and Asia, whether we con-

sider tropical or temperate types. As might be expected, among the species common

to India and Africa, those characteristic of a dry climate largely preponderate. On this

xliv INTRODUCTION.

point Dr. Schweinfurth and Dr. Bayley Balfour’s botanical investigation of the island

of Socotra furnishes conclusive data, collected by the latter *.

About one third of the species of flowering plants of Socotra are endemic; and a

third are species belonging to tropical Africa and tropical Asia. Exclusive of species

having a wider area, about eighty-five of the species of dicotyledons are common to

Africa and Asia, though comparatively few of them penetrate India eastward of

Scindh. The affinities of the entire Flora of Socotra are essentially tropical African

and tropical Asian, but the African element predominates, and is mainly composed

of the features of the Flora of the mountainous region of Abyssinia, with an in-

fusion of West-African, South-African, and Madagascar types. Among South-African

types are Graderia, Babiana, Thamnosma, Lasiocorys, and Euryops, of which the first

two are not known to be represented in the intervening country. In this connection

it may be mentioned that Dr. Aitchison discovered in Afghanistan the very distinct

Fingerhuthia, a genus of grasses previously known only from South Africa. It was

one of the most abundant grasses between Thal and Shinak in the lower Kurram

valley, and presents no obvious characters to separate it specifically from F. africana,

though Boissier has described it as a different species f.

As in the Madagascar flora, so in the Socotran, there are a very few isolated types

whose nearest allies are in the New World. Balfour specially notices his new mono-

typic genera Dirachma (Geraniacese) and Celocarpus (Verbenaces) as belonging to this

category. The three or four Turneracee in Madagascar, the arboreous Mathurina of

the same order in Rodriguez, and Ravenala madagascariensis are other examples ;

yet this element is by no means so prominent in the flora as it would appear to

be in the fauna, judging from Wallace’s remarks thereon f.

To include the whole of tropical Africa in one subregion is unusual, but the facts

seem to warrant this course, and the next division should be into several provinces.

Interruptions in the continuity of the vegetation there are, and the forests of the eastern

side of the continent are probably nowhere so rich as those of Guinea: but their

composition is essentially the same. Taking the first volume of Oliver’s ‘Flora of

Tropical Africa,’ which is, of course, exceedingly fragmentary, it would appear that

about one fifth of the species there enumerated are common to both sides of the con-

tinent ; but subsequent investigations leave no doubt that the proportion is really much

higher. Engler) has analyzed the composition of the flora of tropical Africa as far as

published in the work cited, namely the Polypetale and the Gamopetale to the end of

the Ebenacee; but the results can only be used in respect to the general relationships.

The Leguminose rank first and the Composite next in regard to number of species,

INTRODUCTION. xlv

Very small areas have, however, been thoroughly investigated botanically; hence we

are far from knowing the extent and degree of richness of the flora.

From Engler’s tabulation of Oliver’s enumeration it appears that there is in W. Africa

a larger proportion of endemic species, and fewer widely dispersed genera, than in

K. Africa, and that there are about as many genera otherwise only represented in

Madagascar and the neighbouring islands as there are in E. Africa. Further,

W. Africa has more genera in common with tropical Asia than has E. Africa, which

might be held as a sufficient ground for following Engler and others in regarding

the tropics of the Old World as a primary region. Among Asiatic species discovered

in Angola by Dr. Welwitsch was the remarkable Naregamia alata (Meliaceee),

previously only known from the Deccan peninsula of India. West Africa is relatively

rich in genera otherwise restricted to America, though these are mostly represented by

one or very few species. Many of them have seeds or fruits that float and bear long

immersion in sea-water without injury, hence their presence in Africa may be due to

oceanic currents ; others may have been introduced with ballast. But after eliminating

all these, there remain many remarkable connections between the two floras which are

not so easily explained *.

Gustav Mann’s botanical exploration of the temperate regions of the Cameroons

Mountains in 1861 and 1862 resulted in some remarkable revelations published by

Sir Joseph Hooker +. Nearly all the genera and half of the species are common to

the mountains of Abyssinia, and one of the genera and many of the species are not

found elsewhere. The number of European genera represented in this flora of fifty-six

genera and 237 species found at elevations above 5000 feet is forty-five; thirty-eight of

the genera and twenty-seven of the species are British. The South-African element

is a small one, and consists almost wholly of species which also inhabit Abyssinia; it

includes the genera Anthospermum, Bleria, Ericinella, Peddiea, and Geissorhiza.

Returning to Engler’s summary, the much greater development of the Mediterranean

forms is one of the most striking characteristics of the Flora of Eastern Africa, where

they meet and intermingle with South-African types. More recently the mountains of

eastern tropical Africa have been explored and the results given to the world ¢.

Mr. Thomson’s Kilima-njaro and other mountain collections, more particularly referred

to here, consist of 140 species belonging to 107 genera, and add no fewer than nine

northern genera to the equatorial-African Flora. Altogether they contain twenty-

seven genera and thirty-seven species of a northern type; and the rest are almost

exclusively South-African in character, some of the species being identical—Calodendron

capense, Clematis thunbergiana, and Alepidea amatymbica, for example. In Angola

such South-African types as Faurea (Proteacez), Selaginee, Cyrtandree, Hricacee,

Mesembryanthemum, and Aloe were encountered by Welwitsch *.

The Cape subregion must be dismissed with a reference to the latest essay on the

composition and subdivision of its vegetation f.

The relationships of the Madagascar subregion to tropical and South Africa have been

discussed mainly from data extracted from Mr. Baker’s published contributions to this

rich Flora}, and he has kindly permitted the use of some additional facts taken from

his unpublished catalogue of the known flowering plants of the island. The number

of species is about 3650, belonging to 1000 genera and 141 orders. This number

represents probably less than half the flora of Madagascar ; but it may be regarded as

a fair sample, consisting partly of the upland or Cape element and partly of the low-

land or tropical forest element. The twelve largest orders are :—

Ten of these orders are among the first twelve in the Indian Flora, though occupying

relatively very different positions, and the other two, Tiliaceee and Sterculiacez (replacing

Asclepiadez and Rosacee), are brought into this position by the very large number of

species of Grewia and Dombeya. Tighteen orders are represented by only one species

each, and thirty-five others by twenty species and upwards. Of the endemic order,

Chlenaces, seven genera and twenty-two species have been defined. The Ternstre-

miacee afford an example of a widely spread order poorly represented both in Africa

and Madagascar, whence only one species is recorded. Among characteristic South-

African genera in Madagascar are Hricinella, Philippia, Selago, Aloe, Aristea, Geissorhiza,

Gladiolus, Faurea, Alectra, Harveya, Disa, Satyrium, Lasiosiphon, Phylica, and Antho-

spermum. It is singular, too, that the solitary known Madagascar species of the genera

Viola, Geranium, and Drosera occur in the mountains of tropical Africa, and the Drosera

also in South Africa, though none is known to have a wider range. Sufficient evidence

has perhaps been adduced to justify the course of treating the whole of tropical and South

Africa and the Mascarene islands as a primary region, divisible into three subregions.

§ The same position as in the whole of tropical Africa.

INTRODUCTION. xl vii

Conspicuous among orders absent from the African region are the Cupulifere *, the

characteristic order of trees of the northern region, and hardly less so of the mountains

of tropical Asia (extending southward to New Guinea, though not south of the Ganges

in Western India), and of the mountains of Mexico and Central America, extending

nearly to the equator (Quercus), reappearing both in the American and Australasian

regions in the extreme south (Fagus). Other notable orders or tribes unrepresented in

the African region are:—Magnoliacee, Acerinee (Maples), Pomacee, Hydrangez,

Cornaceze, Caprifoliacee, Vacciniacese, Rhodoracee (Rhododendron), and Abietines.

There is also a very much smaller development of such essentially tropical orders as

the Myrtacez, Aroidex, and Palme than in either the Indian or the South-American

region. On the other hand, the northern genus Erica, which covers thousands of

square miles in Europe with very few species, is represented by hundreds of species

in a comparatively small area in South Africa. Such anomalies occur in nearly

all Floras: take the genera Ranunculus, Epilobium, and Veronica in New Zealand,

for instance, where combined they constitute eight or nine per cent. of the flowering

plants.

The Indian Region.

This, it is assumed, should include the whole of Wallace’s “ Oriental” zoological

region and those portions of his Australasian region indicated in a previous paragraph

(p. xxxvil), and Western Polynesia. Indeed the whole of Polynesia, except the Sand-

wich Islands, might be included. It is not intended to discuss the subdivision of this

region, as the collection and examination of the data would involve great labour. New

Guinea and some of the adjacent islands to the west, and those eastward to the Fiji group,

constitute a distinct subprovince. Whether the remainder of the Malayan Archipelago

should, with the Malayan Peninsula and Cochin China, all be included in one subpro-

vince is not quite so certain. Some parts are exceedingly rich in endemic species and

proportionately in genera, while others, the Philippines for example, are remarkably

poor in endemic generic types, for only six genera in upwards of 1000 are endemic.

It is here, too, that the highest proportion exists of monocotyledons to dicotyledons

in any Flora of considerable extent of. which there are available statistics, it being as

1 to 157+. Further materials will probably modify these figures, though not perhaps

to any great extent.

Miquel records some statistics { of the Flora of the Malayan Archipelago, but as he

took a much more restricted view of genera and species, especially of the latter, than

the other authorities cited, they will only serve for approximate comparisons. The twelve

natural orders most numerous in species are:—1, Leguminose, 676 ; 2, Orchidee, 616 ;

* Even in the wide sense of Bentham and Hooker, for although the European Alnus glutinosa is now widely

spread in South Africa, it is perhaps beyond doubt that it was introduced by man.

down as 9118 species; and the monocotyledons and dicotyledons are as 1 to 3°5. It

should be added that Miquel’s enumeration is very far from complete for many of the

islands.

Sufficient particulars have been given of the botany of British India as a whole, and

it is not intended attempting to characterize the subregions. It may be mentioned

in passing, however, that Malayan types have penetrated to the flank of the Himalayas

and traversed the Deccan peninsula to Ceylon. Thwaites, who enumerates upwards of

2600 phanerogams in Ceylon *, states that the hill Flora resembles very much that of

the Neilgherries ; in the humid south it is more akin to that of the Malay Archipelago,

and in the dry north it is very nearly identical with that of the Coromandel coast.

The supposed special relationships between the Flora of the Deccan peninsula of

India and those of Madagascar and tropical Africa alluded to by many writers, are

probably not greater than those existing between the African region and Malaya.

The South-American Region.

The data brought together in the Appendix relative to the composition and the

distribution of the Flora of Central America and Mexico demonstrate very clearly

that, apart from the peculiar Mexican element and the southward extensions of

northern types, there are two other distinct elements, namely, the Andine and the

Tropical, answering to the two subregions of the South-American region. Though

only two subregions are recognizable, the development of the types characteristic of

each of these subregions varies very much in different areas. Thus, Chili, considered

as a province of the Andine subregion, has Californian connections, and wants some

of the most characteristic and universal of South-American types, while others attain

their maximum development in this province. These peculiarities are chiefly due to

the varying amounts of heat and moisture in different districts. Similar conditions

produce similar results in some districts east of the Andes. How far many of the

characteristic types are generally spread in the South-American region, and within

overlooked, the author gives a sketch of the composition and physiognomies of the vegetation, and brings

together all the data afforded by his own collections and professedly those of CErsted, Warscewicz, Wagner,

Scherzer, Wendland, and Hoffmann. He tabulates the number of species of the natural orders, and his totals

are :—Monocotyledons 209, Dicotyledons 748=957, or 129 less than our total (Vol. IV. p. 218). But the

total is made up in a very different way. Thus, Polakowsky enumerates 127 Composite against our 100, and

only 57 Orchides against our 210.

INTRODUCTION. xlix

what limits others are restricted, may be gathered from the various tables and para-

graphs in the Appendix, more especially from those paragraphs on the distribution of

the more prominent natural orders (vol. iv. pp. 235 to 282), and from the analysis

of a sample of the mountain vegetation (p. 298); but it may be of interest to illus-

trate this further by a few examples, selecting such groups as are spread over the

tropical, or subtropical, and temperate parts of the country.

Foremost among the types not extending into Chili are the Melastomacee ; but their

absence can hardly be explained by climatal conditions alone. The large genus Cuphea,

which ranges from the south-eastern states of North America to Uruguay and Chili,

is represented in the last country by only one species (C. spicata), which covers nearly

the whole area of the genus. Juchsia extends from Mexico to Magellan’s Straits, is

represented in San Domingo by two species, and by three or four species in Brazil,

and it reappears in New Zealand. The Turneracee are essentially temperate and sub-

tropical plants of the western side of the continent, yet there are a few species in

Brazil and Buenos Ayres. The specially characteristic Cactacee are spread all over

South America and the West Indies, though they do not inhabit all districts. Their

northern extensions are given in detail in the fourth volume, page 247. The Brome-

liaceee are spread all over South and Central America and the West Indies, and

penetrate the south-eastern states of North America. The more tropical Cyclanthacee,

Marcgraviacee, Vochysiacee, and Myrtacee-Lecythidee are mainly eastern South

American, though they are also represented in Central America; and the distribution

of such genera as Tropeolum, Baccharis, Coccoloba, Lacistema, Roupala, Lisianthus,

Hyptis, Philodendron, Anthurium, Brassia, Dichea, Epidendrum, Oncidium, and many

others proves that we have to deal with one large primary region. Epiphytal orchids

generally are local, or occupy relatively small geographical areas, yet many of the

American species have a considerable range. A list of thirty Mexican species with

their distribution is given in the fourth volume of this work (p. 270), and it may be

added here that about eighty of the Mexican species extend to the West Indies, and

upwards of 100 to South America, many of the species being the same in the three

areas, as is apparent from the fact that 800 out of 938 are endemic in Mexico. So far

as the distribution*is known, a larger number of the Mexican species reach Brazil

than Peru. Approximately the numbers are :—Colombia (New Granada and Ecuador)

seventy-five species ; Peru twenty-two; Guiana forty-five; and Brazil thirty-six *.

Wallace divides his neotropical zoological region, which corresponds to our South-

American region, into four subregions, namely a Mexican, an Antillean, a Brazilian,

* In the discussion on the northern limits of epiphytal orchids in Mexico (vol. iv. p. 269) the improbability

of Meiracyllium gemma and Odontoglossum madrense being North Mexican was advanced, though in conse-

quence of the habitat being given as Sierra Madre they were 80 recorded. It appears, however (Veitch,

Odontoglossum, p. 51), that they were found in the neighbourhood of Colima, in about 19° N, lat., and far

from the Sierra Madre, in Durango, where Seemann collected.

and a Chilian. From what has preceded it is evident that such a division would not

satisfactorily indicate the leading features of the distribution of plants, as there are

only two distinct elements, the andine and tropical, both represented at different altitudes

in several of the provinces. A better botanical division is an Andean subregion

(which merges into the North Mexican and Californian to the north and into the

Antarctic in the south) and a Tropical subregion, both divisible into several provinces.

In conclusion, reference may be made to a statistical account of the Andine Flora of

Ecuador *, and to Mr. Ball’s recent work +, in which he suggests that the ancient

mountains of Brazil formed a great centre of development of plant life.

The Australasian Region.

This includes the whole of Australia and the adjacent islands, which may be sub-

divided into a south-western and a north-eastern subregion; and New Caledonia and

New Zealand, which constitute other subregions. The remote connections with the

American Andine flora are reviewed in the Appendix (vol. iv. p. 234), and in the

description further on of the Antarctic Flora. Reasons for including New Caledonia

and New Zealand in this region are given in the discussion of Drude’s botanical and

Wallace’s zoological divisions of this part of the world}. It may be of interest to

add here a few statistics of the vegetation of two or three definite areas of the

Australasian region.

The smallness of the numbers of genera and species strikes one most, especially on

comparison with those for the whole of Australia or with those of other areas. That

this is not altogether attributable to insularity is clear from the richness of the Flora of

New Caledonia, computed at 3000 species of phanerogamst. Japan, of similar extent,

and lying in about the same latitudinal position in the north that New Zealand occupies

in the south, shelters nearly a hundred more genera of flowering plants than there are

species in New Zealand, and about three times as many species.

Flora of the Sandwich Islands.

Wallace treats this as a subregion of his Australian region; Drude regards it as a

part of his Indian region; while Engler makes it a province of his ‘ Paleotropical

Floral Kingdom.’ Considering the complexity of the affinities of the flora and its

extent, and the fact that no element largely predominates over the others, it seems

desirable to leave it unattached, without, however, giving it the rank of a primary

region. Could Engler’s ‘Ancient Oceanic Floral Kingdom’ (which includes the

Antarctic forest region of South America, the Southern Island of New Zealand and

outlying islets, extratropical Australia, the Cape, Kerguelen, Amsterdam, Tristan da

Cunha, St. Helena, and Ascension Islands) be regarded as a satisfactory solution of a

difficult problem, the Sandwich Islands should be referred to this rather than to the

Indian region; but the basis of such an arrangement is altogether too hypothetical

from our standpoint, and it brings together the most diverse Floras. As Hillebrand

remarks }, the Sandwich Islands are the only Polynesian group which contain a large

number of indigenous plants of American affinities. Ina previous paragraph (p. xxxix)

examples are given of the more striking genera or species of the different elements of

this highly interesting Flora; and Engler’s tabular view of the Flora and its affinities

affords much fuller information § on this point. Engler’s enumeration contains 669

species of vascular plants, of which he estimates 500, or 74°6 per cent., to be endemic.

The recently published ‘ Flora,’ cited below, of the late Dr. W. Hillebrand, who spent

twenty years in the islands, has increased this number by nearly 200 species, nearly all

of them endemic. His summary is here reproduced.

The 860 species of vascular plants regarded as indigenous belong to 265 genera,

being as 3:25 tol, or about half that in large continental areas such as Mexico,

Australia, and British India. Notwithstanding this low average number of species to a

genus, the most striking feature in the flora is the large number of species of many of the

endemic genera. Thus, Schiedea (Caryophyllacez), 17; Kadua (Rubiaceze), 13; Cler-

montia (Campanulacee), 11; Cyanea (Campanulacee), 28 ; and Stenogyne (Labiatz), 17.

Further the Polynesian genera Pelea (Rutaceze) and Phyllostegia (Labiate) are repre-

sented by 20 and 16 species respectively, and Cyrtandra by 29 species*. Of the

indigenous species 81:4 per cent. are endemic—a proportion exceeded in no other Flora

of the same extent, perhaps, except that of West Australia, in which it is 85 per cent.

Ninety-five orders of Phanerogamia are represented; and the proportion of Mono-

cotyledones to Dicotyledones is as 1 to 4°8, or higher than might have been expected ;

but the former consist largely of Glumifere, petaloid monocots being rare, and orchids |

are represented by only three terrestrial genera, and one endemic species of each

genus.

The question arises whether any of the other islands or groups of islands in the Pacific

can appropriately be associated with the Sandwich Islands. 'The connection with the

other Pacific islands beyond the sea-coast and Australian elements is so very slight that

the Sandwich Islands stand almost completely isolated. Nadeaud f describes a plant

from Tahiti which he refers to Phyllostegia, otherwise exclusively belonging to the

Sandwich Islands; Sclerotheca arborea (Campanulacez), also a native of the Society

Islands, is said to be more nearly related to the American genus Siphocampylus than it

is to the endemic genera of the Sandwich Islands}; Litchia, the only genus of Compo-

sites peculiar to the Society Islands, is related to the Sandwich Islands genera only in

the sense of belonging to the same tribe (Helianthoidew), which is eminently American ;

Pelea is represented in the Navigators Islands. These are practically all the outside

affinities with the peculiar element of the Sandwich Islands flora. The smaller islands

possess no endemic plants; and even the Marquesas are almost destitute of an endemic

element * ; and the vegetation of all the other groups of islands of Eastern Polynesia is

much more largely Malayan in character. Nadeaud includes nineteen species of orchids

in his enumeration of the plants of Tahiti, amongst them half a dozen epiphytal species

of the genera Bolbophyllum and Dendrobium. Seventy-nine orders of Phanerogamia

are represented by about 500 species collectively; but the fragmentary character of the

Flora may be estimated from the fact that thirty-three of the orders are represented

by only one species each. ‘Taking all the facts into consideration, the remainder of

Polynesia may be included in the Indian region.

The Fragmentary Antarctic Flora.

We retain the designation ‘‘ Antarctic,” first employed by Forster and adopted by

Hooker f, for the coldest southern Flora, although it is not geographically an admis-

sible term. ‘There can be little doubt that the present scattered and isolated fragments,

forming the fringe of the southern limits of phanerogamic vegetation, constitute the

remnant of a Flora formerly covering a more extensive area, probably in a higher lati-

tude. The surviving portion is poor, but from its uniform composition it is probably

of remote origin {. Northern species are associated with such as now exist only in the

south, and the same species occur in the scattered fragments of vegetation all round the

hemisphere. It includes the Auckland, Campbell, and Macquarie Islands, Macdonald

(Heard), Kerguelen, Crozets, and Prince Edward Islands, South Georgia and the Falkland

Islands, Fuegia (Tierra del Fuego) and a small portion of South-western Patagonia.

It is true that the vegetation of the Auckland group and Campbell Island is essentially

New Zealand in character and relatively rich, while that of the Falkland Islands is

almost wholly Fuegian ; yet there is a stronger common element than was apparent

when Sir Joseph Hooker wrote his ‘Flora Antarctica.” In the fourth volume

page 234, are tabulated the more striking connections between the Australasian

and Antarctic Floras and that of the mountains of Mexico; and in the Botany of the

‘Challenger’ Expedition is summarized all that was known of the Botany of the

Antarctic Region, and the relationships of the Australian and American Floras§. Since

t In a recent communication from Dr. H. P. Guppy he suggests that the vegetation of these remote islands

is due to the agency of birds. Admitting the probability of such a thing, it must have happened very long ago,

and not altogether in the direction indicated by him, or how is the endemic element to be accounted for? See

‘ Nature,’ xxxviii. p. 40. § Introduction, pp. 50-65, and pt. 2, pp. 183-281.

liv INTRODUCTION.

this was done the Germans have botanically explored South Georgia *, where thirteen

species of flowering plants were collected, nine of which are common to the eastern

_ part of the Antarctic Flora, from Kerguelen to the islands south of New Zealand; four

of them reach New Zealand itself, and one (Colobanthus subulatus) the Alps of

Australia.

In Fuegia the beech-woods (consisting mainly of the deciduous-leaved Fagus antarctica

and the evergreen F. betuloides) are a conspicuous feature; but all the islands are

absolutely treeless, except the Auckland group, where there is an arboreous Myrtacea

(Metrosideros lucida) and two or three other large shrubs or small trees. But the

beech element in the southern hemisphere is one of the most interesting, and it is very

fully described by Hooker +. In the northern hemisphere Fagus sylvatica inhabits

Europe, Asia Minor, Northern Persia, and Japan, but is not known to occur in the

intervening country; and the eastern North-American F. ferruginea is exceedingly

near it, so near, Indeed, as to be regarded by some botanists as a variety. Besides

these there is a Japanese species recently described by Maximowicz}, which strongly

resembles F, sylvatica in foliage, though it is very different in the fruit. Japan,

Northern Persia, North Italy, and Florida.are the southern limits of the genus Fagus

in the northern hemisphere, where it is represented by at most three species. In the

southern hemisphere, on the other hand, there are at least a dozen distinct species

divided between South America, New Zealand, Tasmania, and the mountains of

Victoria and N. S. Wales, with a maximum development in New Zealand and extra-

tropical South-west America. In continental Australia the genus is represented by

two isolated outlying endemic species, one occurring at the head of the Macleay river

in about 31° of latitude, and the other on the Yarra-Yarra in about 37° 30’; and in

America F. obliqua inhabits the Andes in as low a latitude as 33°. Between these

stations and the northern ones indicated above there is no living trace of the genus 9.

The foregoing particulars concerning these two widely separated northern and southern

races of Fagus are given as another illustration of the intimate relationships existing

between the northern and southern Floras, because the genus is so distinct and sharply

defined that there can be no question about the generic identity of the two races, and

because Fagus is the only genus of the characteristic northern Cupulifere that reaches

high southern latitudes. Quercus reaches New Guinea in the east, and Popayan (about

2° 30’ N. lat.) in America. The allied Salicinese (Populus and Salix) also do not reach

§ Fagus argentea and F. gavanica, enumerated in Steudel’s ‘Nomenclator Botanicus,’ attributed to Blume

and recorded from Java, were probably manuscript names given by Blume to some sterile specimens of

Castanopsis. He himself does not mention them in his ‘Cupulifere Javanica,’ nor does Miquel in his

‘Flora Indie Batave,’ and it is almost absolutely certain that no species of Fagus exists in Java.

cold southern latitudes, though one species of Salix is a native of South Africa, and

another species extends about as far south as the northern limit of Fagus in the Andes,

and further south in eastern 8. America.

Let us now briefly examine the composition of the very poor insular portion of the

Antarctic Flora, excluding the Falkland, Campbell, and Auckland Islands. The islands

or groups of islands more or less explored botanically are South Georgia, Marion

(Prince Edward group), the Crozets, Kerguelen, Heard (Macdonald group), and

Macquarie, lying between 38° W. and 160° E. longitude.

The accompanying table demonstrates the existence of an antarctic phanerogamic

element all round the southern hemisphere. It will be perceived that the only island

possessing endemic plants is Kerguelen, and these may possibly yet be discovered in the

Crozets or Prince Edward Island, just as Pringlea antiscorbutica has been. ‘Two genera,

INTRODUCTION. lvii

Pringlea and Lyallia, are confined to the islands under consideration ; two, Plewro-

phyllum and Stilbocarpa, do not extend beyond the New-Zealand region; six are

represented only in the American and the Australasian regions; fourteen are of wide,

mostly of almost universal, distribution, and six of the species are of nearly equally

wide range. The monotypic Pringlea antiscorbutica has no near ally in the southern

hemisphere, but it is closely related to the northern genus Cochlearia, differing more

in habit of growth than in floral structure. And Lyallia is of the same affinity as the

Andine Pycnophyllum and the Mexican Cerdia.

As already stated, the Tristan da Cunha group and Amsterdam and St. Paul Islands

can hardly be included in the antarctic region, unless we make it more extensive in

New Zealand and in South America, because the bulk of the vegetation consists of

Phylica nitida and Spartina arundinacea, types of a warmer region; the former, the

only tree or even shrub larger than the trailing Empetrum, being a Mascarene species,

and the latter a tall reed, whose nearest ally is a native of eastern temperate South

America. Not one of the plants enumerated in the foregoing table is recorded from

the Tristan da Cunha group, and only two, Ranunculus biternatus and Uneinia

compacta, inhabit Amsterdam or St. Paul Island. On the other hand, several of the

plants found in the Tristan and Amsterdam groups are common to New Zealand and

South America. Of the twenty-nine flowering plants known to inhabit the Tristan

group sixteen are apparently endemic; three are South-American and are not repre-

sented eastward, while six extend eastward, three reaching New Zealand. Nineteen

flowering plants are recorded from St. Paul and Amsterdam, eight of which have not

been found elsewhere, and the distribution of the remainder is similar to that of the

Tristan da Cunha non-endemic element. Numerically as to species, then, the compo-

sition of the Tristan and Amsterdam Floras is that of the cold temperate region and

very similar to that of the islands farther south; but several of these species are quite

rare, and the conspicuous vegetation, apart from ferns, is almost wholly Phylica and

Spartina, at least in the Tristan da Cunha group and Amsterdam Island.

CONCLUDING REMARKS.

The facts brought together in the preceding pages and in the ‘ Appendix ’* have an

interest apart from any conclusions arrived at, and whether the views therein put

forward on the botanical regions of the world meet with acceptance or not, it will be

generally conceded that although the broad features of the distribution of plants and

animals are essentially the same, they are by no means identical.

When it is considered how much more potent and diversified are the means of

* It may be well to repeat that this is a review of the results of comparatively recent investigations rather

than an attempt at an exhaustive discussion of the subject.

Lviii INTRODUCTION.

dispersal of plants than are those of animals, the divergences in distribution are no

greater than might be expected.

Beyond this, many natural orders most widely separated from each other in floral

structure repeat the same modifications of their vegetative organs under similar circum-

stances, and possess equal capabilities for adaptation to external conditions.

The present distribution of orders, genera, and species, and all that is known of the

past, seems to point to one original centre of creation and development, and to such

physical conditions at different periods as permitted, or even favoured, the general

spread of all the principal types of plants and the wide migrations of many of the same ~

forms or species. Assuming this to have been so, any system of regional division is

arbitrary, and only useful in proportion to its agreement with the present distribution

of plants, inasmuch as it is merely a foundation on which to build a knowledge ‘of

botanical geography, not a representation or classification of the facts. An exami-

nation of the extensions and isolated remains of extensions of the types characteristic

of each region throws more light on the subject than can otherwise be obtained.

Professor Huxley seems to have been so convinced of this in the Animal Kingdom

that he even goes so far as to say that he thinks it would not be difficult to show that

the whole surface of the globe should be primarily divided into a northern and a

southern region in order to display best the geographical distribution of Birds and

Mammals*. And he further remarks, in connection with his proposed four primary

zoological regionsf (1, Arctogea; 2, Austro-Columbia; 3, Australasia; 4, New

Zealand), that the three latter are in some respects less unlike one another than they

are unlike the first. The same might be said of the plant-regions, taking tropical and

South Africa and the Indian region out of Huxley’s Arctogea.

Even the most highly specialized Floras exhibit merely a local development of species,

of genera, or groups of genera, belonging to orders of universal dispersion, often differing

more strikingly in their vegetative organs (roots, stems, and leaves) than in their repro-

ductive organs (flowers and fruits) from the usual character of the order. The nature of

the medium in which plants grow, combined with the climatal conditions, determine the

character the development assumes, and similar phenomena in development are repeated

in widely-sundered areas, where the prevailing physical conditions are the same or similar.

Familiar examples of this kind of parallelism are offered by the Cactacez of Mexico

and certain African species of the genus Euphorbia, some of which so strongly resemble

the branching Cerei, some the spheroidal Melocacti, as to deceive any but the most

experienced eye. Such American genera as Yucca, Agave, and Dasylirion are replaced

in Africa by Aloe, and in Australia by Xanthorrhwa. Some of the species of a genus

develop tuberous roots, like many of the Australian Sundews, and some thick fleshy

stems, as South-African species of Pelargonium and Vitis, thus adapting themselves to

* Proc. Zool. Soc. Lond. 1868, p. 313. T See ante, p. Xxxiv.

INTRODUCTION. lix

local conditions. Some of the species of a genus having formally flat leaves are

remarkable for their great likeness to a cypress, a lycopod, or a Salicornia. Develop-

ment in this direction is exemplified in some of the New-Zealand species of Veronica.

Another remarkable illustration of the almost universal dispersion of northern types is

offered by the composition of the bulk of the vegetation of the central desert-region of

Australia, where the Chenopodiacee number upwards of a hundred species, including

thirty of Atriplex, fifteen of Kochia, twelve of Chenopodium, and seven of Salicornia,

and associated with these are the European Sueda maritima and Salsola kali, and

several endemic genera, mostly of one or very few species, except Rhagodia (12 species),

which differs chiefly from Chenopodium in having a fleshy fruit.

It has been shown (pp. xix-xxii) how few natural orders are unrepresented in any

one of the large areas under consideration; and ninety-five or nearly half of the

natural orders are represented in the Sandwich Islands. So far as we know, the

African region is poorer than either the South-American or the Indian region, but

further explorations may reveal the existence of several of the natural orders hitherto

undiscovered. Those of relatively restricted areas are almost all small, and consist

of one or few genera and few species, as may be seen on referring to the table on

page xi; and most of them are more definitely characterized than some of the larger,

generally-dispersed orders. Indeed, it is the absence, through destruction, dying

out, or some other cause, of connecting links, that gives some at least of these small

groups the status of natural orders.

Turning to the groups intermediate in rank between orders and genera, a consider-

able number of which are regarded by some botanists as distinct natural orders, we can

better appreciate and estimate the amount of differentiation in development in different

areas. As an illustration, a few of the more important in the thalamifloral Polypetale

are noted. The Fouquieriese, Fremontiew, Limnanthee, Clusiee, Rhizobolez, Marc-

graviee, Malpighiex, Gaudichaudiee, Cuspariee, and Luxembergiew are examples of

distinct tribes or suborders restricted to America; and the Dilleniew, Dombeyee,

Aurantiexw, and Phytocrenee are peculiar to the Old World. On the other hand, the

Zanthoxylee is one out of many tribes that are generally spread in warm countries.

The Lardizabalex are divided between Peru and Chili and Eastern Asia, from North

India to Japan; the Hermanniee are African, with three or four representatives in

Mexico, and the Colletieze are Andine and Australasian.

Similar illustrations of the distribution of plants might be indefinitely multiplied. It

is clear, as Sir Joseph Hooker suggests, that a classification of plants by Linneus or

Jussieu would have been essentially the same had it been based entirely upon Chinese,

Australian, South-American, or Mexican instead of mainly upon European plants.

Whether the plants (and animals) of the earth had a common northern origin, as

supposed by some writers, and the highly differentiated southern forms are descendants

of northern ancestors which have undergone their great differentiation in the south, are

h 2

Ix INTRODUCTION,

problems difficult of solution. As regards a very large number of northern types,

they can be distinctly traced southward. Many exist only in isolated localities, as

they have been driven out by climatal conditions, while others present a nearly

continuous chain; but, speaking generally, they gradually decrease in volume from

north to south. The theory that the Proteacee, Eucalypti, and other southern types

inhabited Europe in early Tertiary times is far from being established on satisfactory

data, and all the indisputable evidence points to a northward migration of these types

and a southern origin. If it can be proved that the prototypes of Eucalyptus,

Proteaceee, &c. existed in Europe, and that the northern outliers of these types are

survivals of stragglers of the southward migration, it follows that differentiation equal

to the greatest differentiation in the whole world took place in the northern hemi-

sphere, and that there has been comparatively little beyond specific differentiation in

the southern. This may beso, and the extraordinary development of the genera Erica,

Mesembryanthemum, and Pelargonium in South Africa and of Ranunculus, Epilodium,

and Veronica in New Zealand might be cited in support of the argument.

In conclusion, a few additional remarks on the adoption of a few large primary

regions. With regard to treating the north temperate and arctic countries as one

primary region, it may be contended that, although there is a large number of genera

common to Europe and western North America, to give an extreme illustration*, there is

also a larger number not represented in the two countries, including genera numerous in

species, such as Medicago, Cousinia, and Acantholimon on the one hand, and Dalea, Gilia,

and Pentstemon on the other. This is true; but are the differences greater than

between Ceylon and Borneo or between the latter and New Guinea, or between South-

west Australia and South-east Australia? Among the numerous genera peculiar to

West Australia are such prominent ones as Kingia, Dasypogon, Anigozanthos, Conostylis,

Andersonia, Dryandra, Pileanthus, Verticordia, Tremandra, Platytheca, and Chorilena.

Among those common to the two are Kucalyptus, Persoonia, Hakea, Grevillea, Dampiera,

Leschenaultia, Myoporinee, and Xanthorrhea. Further, upwards of eighty per cent.

of the species of vascular plants are endemic. ‘The absence of a large number of orders

and suborders represented in Eastern Australia is also remarkable, and on a par with

the poverty of the European Flora as contrasted with the Chino-Japanese or the North-

American. Nevertheless few persons would refer these two areas to different primary

botanical regions.

* As already urged, it is a comparison of the vegetation of Eastern Asia and Eastern North America that

reveals the most striking similarities; the affinities between these two regions being much stronger than those

existing between the vegetation of Europe and Eastern Asia.

t Sir Joseph Hooker sufficiently indicates in his essay on the Australian Flora the striking characteristics

of, and the more striking diversities between, the vegetation of Eastern and Western Australia; but Dr. Engler’s

tabular view and partial analysis of the Flora of the whole of Australia (Versuch, ii, pp. 12-54) brings out

‘these peculiarities much more prominently.

INTRODUCTION. Ixi

It is usual to rank the South-African Flora as a primary region, but here it is made

a subregion of a region comprising tropical and South Africa and the Mascarene Islands,

because the mountain flora of Madagascar and of tropical Africa, especially eastern, is

largely composed of South-African types, a fact that is in a manner suppressed in

treating them as separate regions. The same arguments apply with regard to South

America.

In a cartographical representation of the floras of the World it seems at first easy

enough to indicate the centres and extensions, or isolated mountain-areas, of each, but

the practical difficulties are insurmountable. Yet it would not be difficult to show, on

so many maps of the world, the areas and extensions into other regions of the five

regions proposed. There would also be space for indicating the density and limits of

some of the leading types. This should not be done, however, in the sense of

denominating a vast area as the “ province of the tea-tree,” the “ province of the cedar,”

and so on, which conveys an altogether false impression ; yet unfortunately this method —

has been continued in the latest Atlas of Plant Distribution.

Sir Joseph Hooker, who has kindly read the proof-sheets of the foregoing pages

and suggested many improvements, and who has consented to write a brief commentary

on this ‘Introduction,’ does not share some of the opinions expressed by the writer,

who himself might modify them for a primary botanical division of the world based on

climatal conditions alone. To a great extent the facts speak for themselves, yet it is

doubtful whether any two persons would deal with them in exactly the same manner.

It is perhaps unnecessary to apologize for the occasional repetition of a fact or an

argument, or for slight discrepancies in the figures cited in different places, as all persons

engaged or interested in similar work can appreciate the difficulties of the task, and

will excuse imperfections of such a nature.

A COMMENTARY

Mr. HEMSLEY’S INTRODUCTION AND APPENDIX

TO THE

BOTANICAL PART OF THE ‘BIOLOGIA CENTRALI-AMERICANA.’ |

By Sir J. D. HOOKER, Late Director oF THE RoyaL GARDENS, Kew.

Havine been deeply interested in the progress of Mr. Hemsley’s work on the Botanical

portion of the ‘ Biologia Centrali-Americana,’ and especially in that author’s elaboration

of the important Appendix relating to Botanical Geography, which is contained in the

fourth volume, I have been requested by Messrs. Salvin and Godman to contribute to

the pages of their ‘ Biologia’ some observations of my own relating to the scope and

character of the work accomplished by Mr. Hemsley, especially as regards its value

as advancing knowledge of the geographical distribution of plants.

At the same time, I have been asked to add, to any comments of my own upon the

contents of the Appendix, my conceptions of the principles which should guide the

_ botanical geographer in the limitation of the primary botanical regions of the globe—

conceptions which have been tardily matured, during botanical visits to many countries

and a long familiarity with the dominant features of their Floras, obtained both on

the spot and from a study of large herbaria.

No country of equal area presents a richer or more varied vegetation than Mexico.

Except perhaps the Javan and Indian, no tropical Flora of great extent is so well

explored and so fully represented by collections; and none has been subjected to so

searching an analysis, in respect of the correlation of its botanical features and the defi-

nition of its botanical regions, as has this Flora under Mr. Hemsley’s judicious, pains-

taking, and accurate methods of study. My view of the merit and completeness of

this part of the work urged me to suggest to the authors of the ‘ Biologia’ the desira-

COMMENTARY ON THE INTRODUCTION AND APPENDIX. Ixiii

bility of Mr. Hemsley’s instituting a closer comparison between the Mexican Flora and

that of some tropical region in the Old World presenting as rich and varied a vege-

tation, and I indicated the British-Indian Flora as especially suitable, both on this

account, and because the ‘Flora of British India’ was sufficiently advanced in

respect of available published and unpublished materials to supply accurate data for

such a comparison. And further it appeared to me that by availing himself, together

with these materials, of the geographical data appended to every genus of phanerogamic

plants contained in the recently-concluded ‘ Genera Plantarum,’ Mr, Hemsley might

very greatly advance that most instructive branch of phytogeography which originated

independently and coincidently in the minds of Humboldt and Brown, and to which the

former gave the name of Arithmetice botanices.

Messrs. Godman and Salvin cordially responded to my suggestion, and I feel sure.

that the results embodied in the “ Statistics of the Phanerogamic Flora of the World”

(Introduction, pp. ix—lxi) will be received with gratitude by all botanists as a very

valuable supplement to a work that owes its existence to those naturalists’ travels,

collections, learned labours, and munificence.

The tables at p. xv and following of the Introduction are particularly valuable,

and give information previously unattainable. ‘The areas compared are approximately

within the same latitudes, 9° N. and 83°N., but separated by nearly 180° of longitude,

the Asiatic in 70° to 95° E., the American 80° to 115° W. Each presents a hot, moist

tropical, a temperate, and a frigid climate. It is impossible to find, in the Old and

New Worlds respectively, two areas more similar as to physical features, or in which

the vegetation of their respective continents is more fully represented; and yet the

comparison of their Floras shows that, with an almost total diversity of species, genera,

and of many natural orders, the proportion of monocotyledonous to dicotyledonous

plants is nearly the same in each; that the number of natural orders is only 12 fewer

in Mexico; that the number of species in each differs by only 2000 (11,626 in Mexico,

13,647 in India); that the average number of genera in each order is nearly the same

in each (11 in Mexico and 13 in India); that the average number of species in each

genus even more nearly coincides (6:4 in Mexico and 6-0 in India) ; and, more singular

still, that the percentage of endemic species in each differs by only 2 per cent.

It is instructive to observe that these marked resemblances in proportions do not

arise out of a resemblance in the elements from which they are derived; for, turning

to the natural orders that contribute largest to the Flora of each area, they are very

differently represented as to number of species in each. Composite, which take the

first place in the Flora of the globe and of Mexico, are reduced to the sixth place in

India. Leguminosee, which are second to Composite alone, are second in both Mexico

and India; but Orchidew, which hold the third place in the world and in Mexico, are

first in India; Rubiacew, the fourth in the world, are the seventh in Mexico and fifth

in India; grasses are fifth in the world and in Mexico, but only third in India.

lxiv | COMMENTARY ON THE

Descending in the systematic scale to the lowest term of the series, the differences

between the elements of the two Floras become greater and greater, until genera are

reached; thus, as Mr. Hemsley shows, only 25 to 26 per cent. of these are common to

the two regions. As yet data do not suffice to ascertain the exact number of species

common to India and Mexico, but it may not exceed 600 of the 25,273 which is

approximately the sum of the species of both Foras.

It is not my purpose to discuss the nature or origin of the unexpected likenesses and

expected unlikenesses that Mr. Hemsley has shown to exist between the Floras of

Mexico and India: of these the former are due to causes which have influenced vege-

tation as a whole; the latter to more or less local causes. As an illustration of what

I mean, I would say that the conditions which have resulted in monocotyledons main-

taining their numerical position of one to four or thereabouts of dicotyledons in the

globe and in all large areas thereof are, in the present state of science, inscrutable ; but

that the comparatively low number of Compositze in India is explicable by the intrusion

into India of the Malayan Flora, which is abnormally deficient in Composite. Not

that this offers any real solution of this latter phenomenon, which lies much deeper.

It must be shown whether the intrusive Malayan Flora found in India a Flora already

deficient in Composite, or whether it prevailed over and displaced the pre-existing

native Composite ; and it must also be shown why the Malayan Flora is deficient in

this ubiquitously dominant element of all other floras, whether tropical, temperate, or

frigid, insular or continental, humid or arid.

It would be very interesting to know whether any of the larger divisions of the

animal kingdom present phenomena comparable with those derived from large remote

botanical areas. It may be supposed that the great unconformity that exists between

the geographical regions of plants and those of animals, as traced out by the most

competent of zoologists, and which unconformity is so strongly, and as I think rightly,

insisted upon by Mr. Hemsley, is opposed to such a parallelism existing ; but I do net

see the force of this objection if, as I think, the problems presented by these “ Arith-

metics ” are deeper than those of regional distribution.

Another point of resemblance between the Floras of Mexico and India is that each

is botanically as well as geographically a n@ud. The lofty mountains in each are con-

tinuations from more temperate latitudes in the north, favouring an immigration of

temperate species which have retained their characters in the higher elevations and

become modified or been extinguished in the lower. In each Rosacew, oaks, and

Coniferee of northern forms descend into the tropics, even to 3000 feet elevation, whilst

palms ascend to 8000; and in each epiphytic orchids abound, ascending in cool tem-

perate regions to 8000 feet and upwards.

Perhaps the most striking case of parallelism in the Floras of tropical America and

Asia, as prominently put forward by Mr. Hemsley, is that in each so many temperate

types, especially oaks and Pinus proper, are continued far into the tropics, but cease at

INTRODUCTION AND APPENDIX. lxv

or near the equator. If, as has with much probability been surmised, the existing types

of vegetation originated in northern latitudes and by migration southwards, and by

differentiation and dispersion, peopled the southern hemisphere, there is no obvious

obstacle to the prolongation of these two particular types (and many others) into South

America, New Guinea, and Australia. But there is this difference between the oaks of

the tropics of the Old World and those of the New, that the Asiatic in their prolongation

southward to Malacca and thence eastward to Borneo in descending to the sea-level

assume different types of structure from their northern allies, forming distinctly tropical

sections of the genus, as Cyclobalanus, Chlamidobalanus, Lepidobalanus, and Castanopsis.

On the other hand, the tropical-American oaks where they descend to the sea-level do

not assume a character sectionally differing from temperate-American species. It is

startling to have to regard the genus Quercus as tropical rather than temperate; but so

it is, and especially in India, where about 70 species are purely tropical and only 12

purely temperate.

Turning now to the concluding pages of Mr. Hemsley’s Introduction (pp. xxxix-Ixi),

which are devoted to an exposition of the primary botanical regions of the globe, I

find that these regions are based upon far more complete and reliable data than had

previously been available. In the last paragraph but one Mr. Hemsley remarks that

I do not share some of the opinions which he has expressed in his previous pages. This

remark must not be taken as conveying the impression that I dispute either his facts or

methods. I shall now, in preference to discussing either, give in outline my own idea

of the principal botanical regions of the globe, from which it will be seen how far I

differ from him in the limitation of the primary Floras of the globe.

I limit the primary botanical regions of the globe to two, the Tropical and the

Temperate ; these are distinguished by both climatic and botanical features—tropical-

country plants will not, as a rule, bear a temperate climate, nor temperate-country

plants a tropical climate. Botanically the two regions are distinguished by the restric-

tion of certain natural orders to one or the other, and the prevalence of others in one

or the other. The geographical limit between these Floras in either hemisphere varies

with every few degrees of longitude, being affected by elevation of surface and local

climatal conditions. I do not distinguish the northern and southern Frigid Floras as

primary regions separate from the Temperate, for these regions contain no genera and

very few species different from the Temperate, and the geographical limits of any group

of species that may be selected as inhabiting the coldest region of the globe are unde-

finable by latitude or by isothermal or isotheral lines.

If a distinctive name is desirable for the two primary regions, I would suggest that

of Botanical Empires.

The regions next in importance to the two primary are in my view seven,—two

north temperate, of the Eastern or Old and Western or New World respectively ; two

tropical, corresponding to the above; and three south temperate (America, Africa, and

BIOL. CENTR.-AMER., Bot. Vol. I., October 1888. i

Ixvi COMMENTARY ON THE

Australia). Ifthe term Empire is applicable to the primary divisions, that of Kingdoms

may be accepted for thesecondary. I have a few observations to offer upon these seven

kingdoms :— | |

I. The north temperate Kingdom of the Old World.—This coincides with the Palearctic

zoological region of Dr. Sclater, with the exception that it includes Greenland, the Flora

of which, as I have elsewhere shown, is more European than American. In detail of

circumscription,it, with this exception, follows exactly the sinuous course traced for it

by Wallace in the third chapter of ‘Island Life.’

In attaching greater importance than do Mr. Hemsley and other botanists to the

difference between north temperate Floras of the Old and New Worlds, I am influenced

by a somewhat close study of the elements of each, together with impressions gathered

from journeys in both continents. I am aware that such impressions are often quite

untrustworthy, and must be so if not supported by adequate data derived from a com-

parison and contrast of the plants constituting the Floras of the two areas.

The chief arguments for the uniting these kingdoms into one are the prevalence of

coniferous and cupuliferous and other trees of the same genera in both, that a consi-

derable number of other genera are common to both, and that the Floras of their higher

latitudes are practically one. But it would not be difficult to give examples of similar

tropical features which prevail over the continents of the Old and New Worlds, and

which might with much reason be adduced in favour of uniting them into one region,

reinforced as the argument would be by the great number of genera (more by far than

is usually supposed) that are common to the tropics of the Old and New Worlds.

Having regard to the composition of the Flora of the two northern temperate regions,

if the Floras of their middle and southern temperate latitudes are taken into account,

the botanical differences between them appear to me far to outweigh the resemblances.

Of the forest-trees scarcely one is conspecific with an Old-World one. Of the 10,000

(or thereabouts) known temperate North-American flowering plants not more than 700

are common to Europe, and these include upwards of 150 water and marsh plants of

more or less mundane distribution; and there are nearly fifty natural orders in tempe-

rate America that are wanting in Europe. Again, taking Boissier’s ‘ Flora Orientalis’

as a standard of comparison with that of temperate North America, I find that of 1100

oriental genera less than 400 are American, and of about 9500 species less than 350 are

American. In Gray’s ‘ Flora of the Eastern United States,’ of nearly 2300 species not

370 are European. In Coulter’s ‘ Flora of the Rocky-Mountain Region,’ out of about

1800 species about 300 alone are European, and of the Californian Flora of 2700 species

there are not 230 European.

But these statistical data, important as they are, are far less so than what is supplied

by the genera and species themselves. The generic, tribal, and specific differences

between the Liliaces, Labiate, Scrophularinee, Umbellifere, Onagracee, Leguminose,

INTRODUCTION AND APPENDIX. xvii

and Malvacee of America and Europe are no less striking than is the comparative

rarity in the former country of Cruciferze, Caryophyllee, Geraniacee, Carduacee,

Campanulacee, Lobeliaceze, Primulaces, and Orchidex, and the prevalence of Vitacex,

Anacardiacee, Crategi, Asclepiadeee, Polemoniacer, Nyctaginex, and Cyperacez.

Turning now to the Floras of the Asiatic and American continents, it is difficult to

say which is the most striking phenomenon, the wonderful identity of certain isolated

genera and species of the eastern shores and islands of the Old World with those of

the eastern side of the New World (and which has been so admirably worked out

and explained by Asa Gray), or the total dissimilarity of the Asiatic and American

temperate Floras in other respects. I may select the Japan group in illustration of

both phenomena, because geographically it is perfectly well suited for a comparison

with the Pacific-coast Flora of America, and because it is the head-quarters in Asia

of the representative genera and species of the Eastern American Flora. The Japanese

Flora contains about 200 species common to North America, but nearly three fourths

of these are species found all round the globe in the north temperate regions; the

remainder are chiefly the Eastern American genera and species alluded to above.

Of the North-American Flora proper there is not a trace in Japan; there is not one

of its multitude (nearly 150) of peculiar genera to be found in Japan of Cruciferae,

Capparidee, Papaveracee, Rosaceze, Saxifragee, Onagracee, Composite, Polemo-

niaceee, Hydrophyllaceee, Scrophularinee, Nyctagineee, Polygonez, and Liliacex, nor

are there any endemic representatives of them. Further, the numerical proportions

of the Japanese orders are European and Asiatic, not American. Leguminose, of

which there are only 19 genera in California, is represented by 41 in Japan; though.

the total number of phanerogamous genera is 879 in California and only 839 in Japan.

Of Orchidee there are only 10 genera and 22 species in California against 34 genera

and 67 species in Japan*, and the contrast might be carried much further by taking

many other natural families. In short, the differences between the Palearctic and

Nearctic botanical areas are so many and various that I have no hesitation in

regarding them as two botanical kingdoms.

Il. The tropical Kingdoms of the Old and New World.—<An analysis of the Floras

of the Old and New World as a whole shows, as was to be anticipated, that the Old

World Flora is by far the richest ; it contains probably 6000 known genera of Flowering

Plants, and the New World nearly 4000, there being only about 1200 genera common

to both. It is a singular fact that the ratios of Monocotyledons to Dicotyledons is the

same for the endemic genera of the Old World (1°48), for the endemic genera of the

New World (1:46), and for the genera common to both (1°47). How far this holds

* The Californian genera of Orchids are, with one exception, European, and most of them Asiatic, which

renders the absence of so many in Japan very anomalous.

Ixviii COMMENTARY ON THE INTRODUCTION AND APPENDIX.

good for the species I have not attempted to ascertain, nor have I attempted the sepa-

ration of the tropical genera of either world for the totals above given.

I regard the tropical African Flora as a subdivision of that of the Old World, because

I find no other essential difference between the Asiatic and African vegetations taken as

wholes than the poverty of the latter, and because the peculiar botanical features of

large tracts of Asia are repeated in Africa. Thus the Punjab, Scinde, and S. Persian

Flora is largely represented all over north tropical Africa, extending to the Cape de

Verde Islands; the notable absence in the Deccan peninsula of India of Cupulifere and

the extreme rarity of Conifere are conspicuous characters of all tropical Africa; and the

Indo-Malayan Flora has- its representatives in Madagascar, and measurably on the

coasts of the African mainland. If any part of the tropical Old World could be sepa-

rated as a primary region that should rank as a kingdom, it would be New Guinea.

III. The three Southern temperate regions | (Extratropical America, Africa, and

Australia).—I cannot accept the merging the South-African Flora into the tropical

African. Of the six well-defined botanical provinces of South Africa so ably established

and limited by Mr. Bolus, not one is represented anywhere in tropical Africa, where

there is no region of heaths, of Composite, of Crassulaceew, of Campanulacee, of Prote-

ace, and of Restiacese, and where such few representative species of these orders as do

occur are either confined to mountain-regions or are isolated amongst the prevalent

Indian types of vegetation. On the other hand, the genuinely tropical types of Africa

are few and scattered in its south temperate regions, where the Anonacee, Menisper-

macee, Guttiferee, Rubiacee, Acanthacee, &c. are hardly even represented, and only

locally. It is true that Mr. Bolus designates the western seaboard of South Africa as

the tropical region, mainly because a palm there extends to 33° 30! lat. south; but as

in New Zealand, the Himalayas, and at Gibraltar palms enter the middle temperate

zone, their presence does not necessarily imply a tropical heat; and as the plants of

the so-called tropical South-African region require no greater heat than that of an

English conservatory, I cannot regard them as typical of a tropical Flora.

In the above sketch I have taken no account of exceptional Floras like those of

St. Helena and the Sandwich Islands, whose relationships must be determined by a study

of the flowering plants they contain. Nor have I taken into account theoretical con-

siderations of any kind. |

With regard to exact geographical limitations of any of these seven botanical areas,

such are possible only where geographical features present insuperable obstacles to the

further spread of the plants that characterize them. Where two are conterminous, there

is always a neutral ground, often a very broad one, and this neutral ground may itself

present a Flora which may be regarded as either tropical or temperate.

This is a very distinct plant; but there was some difficulty in deciding what genus

it should be placed in. Dr. A. Gray mentions (Proc. Am. Acad. Arts and Sciences, vi.

p. 188) Coulter’s number 684, and states that it is a strict congener of Lodanthus pin-

natifidus ; but the latter has perfectly accumbent cotyledons. On the whole our plant

agrees very well with Thelypodium as defined by Watson (‘ Botany of California,’

i. p. 87), which includes Pachypodiwm of Nuttall.

from Galeotti’s specimen, which agrees very well with their description as far as it

glabrous ; hence it is possible that they are different species.

Although we have not seen authentically named specimens of Arenaria bryoides,

Willd., we have no doubt that the Guatemala plant is at most no more than a variety of

that species. It agrees almost exactly with the excellent description cited above, except

that “folia enervia” is not applicable; but the meaning of this is not quite clear.

The specimens collected by Linden (no. 938) on the Peak of Orizaba, and named A.

bryoides, Willd., in Kew herbarium, differ from the Guatemala plant in having less

crowded, thinner leaves, decidedly ciliate throughout their entire length, and in having

smaller flowers with more prominently ciliate sepals.

Tribe MARCGRAVIEA.

This tribe is restricted to Tropical America. Delpino (‘ Nuovo Giornale Botanico

Italiano,’ i. pp. 257-290) has given a monographic review of the species known to him ;

and Dr. Wittmack has more recently monographed the group in the ‘ Flora Brasili-

TERNSTROMIACEA. 91

This has the largest pitchers of any described species of the genus. The specimens

we have seen are very much shrivelled ; but Seemann states (/. c.) that they are about the

size of those of Cephalotus, though much more fleshy and substantial, and of a green

colour blotched with a dull reddish brown.

Since our Plate was printed, Wittmack (FI. Bras. fasc. lxxxi. p. 231) has referred

this species to I. picta, Willd., but, as we think, on insufficient grounds. Willdenow’s

species was founded upon a barren or climbing branch ; and Wittmack has seen flowerless

specimens, collected by Martius in Brazil, having both climbing branches with leaves

resembling those of Willdenow’s plant, and flowering branches with leaves resembling

those of Seemann’s species, the leaves of the climbing branches of which are unknown.

These three he identifies as one and the same species.

having solid transformed bracts which secrete nectar on the outside, whilst in Souroubea

they are hollow, the secretion being formed inside. The Central-American and Mexican

species hitherto collected belong to the latter genus or section. Considering it as one

genus, the species are dispersed over Eastern Tropical South America, northward to

9 TERNSTREMIACER,

The large scabrous leaves and loosely paniculate flowers distinguish this from all the

other Mexican species. A specimen collected by Hahn at Misantla may belong to the

same species. It appears to differ only in the more ferruginous, less copious indu-

mentum, broader leaves rounded at the base, and more compact inflorescence.

EXPLANATION OF TAB. VIII.

Fig. 1, flower and bracts; 2, flower, with bracts removed; 3, stamens and pistil; 4, anther; 5,

| sepal; 6, petal; 7, pistil and remains of filaments ; 8, vertical section of ovary; 9, transverse

section of ovary; 10, ovule; 11, ripe fruit ; 12, vertical section of the same, showing the plu-

mule of the solitary seed; 13, vertical section of the same through the cotyledons ; 14, cross

section of the exalbuminous seed, the testa of which has been absorbed during maturation.

There seems little doubt that the plant at first imperfectly described by Planchon and

Triana is the same as the Panama plant, of which there is abundant material at Kew,

collected by Hayes. The only points of difference are the apparently 5-celled ovary

and white flowers of the Colombian specimens.

Altogether this is one of the most singular plants that has come under our observa-

tion ; and therefore we have given the generic character. The fact that the testa of the

seed is almost wholly absorbed during maturation, leaving the embryo lying naked in

the fruit, is of itself exceedingly interesting. The plumule, as described above, is

largely developed in the dormant seed; and, according to a note in Hb. Kew, by

Hayes, it grows in germination to a considerable length before the radicle begins to

elongate.

128 STERCULIACEA.

Planchon and -Triana (Prodr. Fl. Nov. Gran. i. p. 195) unite Quararibea with

Myrodia; but there are characters by which these two genera may be distinguished,

though they are closely allied. The species here described and figured certainly has

2-celled anthers; therefore it is placed next to Myrodia, in this family, instead of

leaving it in the Malvacee.

SoutH Mexico, near Huanujuato (Cavanilles).

Cavanilles first published this plant (J. ¢.), stating that it was raised in the Madrid

garden from Mexican seeds; probably this was a mistake. Masters (Oliver’s ‘Flora

Tropical: Africa,’ i. p. 231) refers Cavanilles’s figure to Melhania abyssinica, without any

explanation whatever. Bentham and Hooker (J. c.) quote Cavanilles, but make no

mention of a Mexican or American species. Certainly a cultivated specimen in

Hb. Kew., bearing the name Brotera alba, appears to be identical with undoubted

M. abyssinica, which is a native of Scinde, Abyssinia, and the Cape-Verd Islands.

Mr. Bentham originally determined these specimens to be W. concolor; but after-

wards, in a note in Hb. Kew., recorded that he believed this to be an error, and that

Hartweg’s plant belonged to a new species. We have not seen authentic specimens of

W. concolor; but, according to the description, it differs from the present species in

having slender flexible branches, distinctly petiolate leaves with an inflexed margin, and

in the flowers being scarcely 3 lines in diameter.

Tribe HIPPOCRATEA.

[Bentham and Hooker, J. ¢., refer all the species of this tribe to the two genera

Hippocratea and Salacia, both having a wide range of distribution in tropical countries ;

but Mr. Miers (Linn. Trans. xxviii.) makes no fewer than sixteen genera, besides largely

Increasing the number of species. Planchon and Triana (Ann. Sc. Nat. série 5, vol. xvi.

p. 370 &c.) propose another genus. There can be no doubt, we think, with complete

material, characters will be found for some new genera; but not being able to decide

upon the merits of what has been done by the writers named, we keep the species in

the genera as we find them at Kew, with the names under which they have been pub-

lished by Miers and others. ] |

Baillon makes a distinct genus of this species, based upon its simple leaves, regular

only one of importance, as there are two or three Daleas having simple leaves, and others

having more or less regularly arranged glands on the calyx.

Although the stipules of Parkinson’s plant are enormously larger than those figured

essential particulars. Presl’s figure is not well drawn ; and he does not give a more pre-

cise habitat than “Tropical America.”

Since the publication of the diagnosis of this species, we have had occasion to com-

pare a number of specimens of various species of the genus; and there is no doubt that

this is very near, if not identical with, B. intermedia, Moric. ; but the pod of Moricand’s

plant is represented as double the length of those of our B. stipitata. Our plant has

also much the aspect of B. foliolosa, from which it differs in its more abundant and per-

sistent tomentum, softer leaves, shorter pedicels, longer stipes of the pod, &c.

is easily distinguished by its short dense bracteate flower-spikes. Possibly it may

At first sight Parry and Palmer's specimens look very different from the typical _

specimens collected by Wright, having comparatively stout, straight branches and pods

at least twice as broad; but in other respects they agree. Moreover the pods in the

typical specimens have all been interrupted in their growth by the larve of some

insect, and have probably not attained their normal size.

SAXIFRAGACE. | 381

Order XLVIII. SAXIFRAGACE.

Saxifragee, Benth. et Hook. Gen. Plant. 1. p. 629.

About seventy-five genera, embracing 550 species, are referred to this order. There

are herbaceous, shrubby, and arboreous species; and they grow chiefly in the temperate

and frigid regions of the northern hemisphere, less numerous in the south, and very

few in the tropics.

Tribe SAXIFRAGEA.

This tribe is the most numerous in species; and they are all herbaceous plants.

1. SAXTFRAGA.

Saxifraga, Linn. Gen. Plant. n. 559; Benth. et Hook. Gen. Plant. i. p. 635.

A genus of about 160 species, almost confined to the temperate and frigid regions of

the northern hemisphere, where they are generally diffused. A few species occur in

South America; but the genus is not represented either in South Africa, Australia, or

the Pacific islands.

We have referred Andrieux’s specimens to H. longipetala, although ten stamens are

represented in the analysis of the flowers in De Candolle’s tracing, quoted above. The

ten stamens is probably a mistake ; for only five are shown in the flowers on the plant

drawn. In all other respects Andrieux’s specimens agree with the plant traced. This

species differs from H. orizabensis in its much slenderer scapes and smaller, more

numerous flowers, and much smaller stipules.

Order LIV. MYRTACEE.

Myrtacee, Benth. et Hook. Gen. Plant. i. p. 690. .

A large order of trees and shrubs, comprising about eighty genera and nearly 2000

species. Two tribes are almost exclusively restricted to Australia and neighbouring

islands, and include upwards of forty genera and 650 species. The Myrtee and

Lecythides combined are even more numerous in South America as to species; and

there is also a considerable number in Tropical and Subtropical Asia. About a dozen

species are found in the whole of Africa; and one is a native of the south of Europe.

In America none is found north of Mexico and South Florida.

Tribe MYRTEA.

This tribe is generally diffused, but by far most numerous in South America. Berg

(Flora Brasiliensis, xiv. pars 1) estimates the number of American species of this tribe

at 1630; but he appears to have unduly multiplied them, and many of the following

can only be considered slight varieties.

Melastomacee, Benth. et Hook. Gen. Plant. i. p. 725; Triana in Trans. Linn. Soc. xxviii.

Bentham and Hooker describe 134 genera, and estimate the number of species at

1800. ‘Triana enumerates 1763 species, and retains the same number of genera. The

family is generally dispersed in tropical and subtropical regions, but much more

numerous in America than in the Old World, and very rare in Australia, the Pacific

islands, and South Africa. A few species are found in Eastern Temperate North

America. Where not otherwise stated, the genera consist entirely of woody plants,

either shrubby or arboreous.

(united by Koehne with C. melanium), from which it differs in its larger flowers, uncinu-

late calyx-teeth, broader obovate petals, and bearded filaments. Possibly more complete

material of the Cuban plant may lead to their union. Grisebach’s description is alto-

From a specimen in the Berlin herbarium there is no doubt that Bentham’s C. platy-

centra is the same as La Llave and Lexarza’s C. bustamanta. The label accompanying

the specimen in question bears the following inscription :—“ Cuphea bustamanti (sic, nec

bustamanta) sub hoc superiori nomine ex h. bot. Mex. accepi. Oct. 29, ScHIEDE.”

This plant is exactly the same as C. platycentra, Benth. ; and it is also doubtless the

true C, bustamanta, which was published only some three or four years before Schiede

travelled in Mexico.

This species is closely allied to C. utriculosa, Koehne, and C. rivularis, Seem.,

differing from the former in its larger flowers, unequal calyx-lobes, insertion of the

stamens, &c., and from the latter in being almost glabrous, and in its longer, very

slender peduncles. According to Koehne, the species of this section have only nine sta-

mens; but we have found eleven in all the specimens of the species we have examined.

It is somewhat doubtful whether this or F. splendens, as defined here, is the true

F. splendens of Zuccarini, which is very imperfectly described ; but, as far as the descrip-

tion goes, it accords better with the species commonly cultivated in this country, and

retained here under the name, than with the present plant. This species differs in

being much less pubescent, in the calyx-tube tapering gradually downwards and not

being fleshy and swollen immediately above the ovary, and in the nearly rotundate

petals. It is possible that a more complete series of specimens would furnish connecting-

links between F. intermedia, F. splendens, and F. cordifolia. Hartweg collected and

dried specimens of our F. intermedia, and sent home seeds of the plant generally known

as . splendens, of which there are also wild specimens at Kew, both from Guatemala

and South Mexico.

Whether the characters upon which this species is founded are constant, it is impos-

sible to say with the limited material before us; but it is probable that this may

eventually prove to be no more than an extreme form of H. elegans. It is named in

honour of Professor Mariano Barcena, of the National Museum of Mexico, who has

recently published a ‘ Noticia Cientifica de una parte del Estado de Hidalgo.’ In this

little work he enumerates the characteristic plants of the district under consideration, and

among other things describes and figures a Hauya, which he thinks may be distinct from

the original 4. elegans. His figure is not drawn with botanical precision, and cannot

be said to represent exactly either of the forms here admitted to the rank of species ;

nor does his description agree in all particulars with either this or H. elegans.

This differs mainly from our H. barcene in having much larger flowers, with relatively

longer petals and shorter calyx-lobes, and in the dense velvety tomentum. The

Order LXV. CACTACE.

Cactee, Benth. et Hook. Gen. Plant. 1. p. 845.

With the exception of one or two species of Rhipsalis, which extend to Africa,

Mauritius, and Ceylon, this family is exclusively American, though some species of

_Nopalea and Opuntia are now so thoroughly naturalized in certain parts of the Old

World, especially in the Mediterranean region, as to have all the appearance of being

indigenous. Indeed some botanists incline to the opinion that some of the species

may be really indigenous there, just as other families and genera are represented in

the two continents by closely allied, though undoubtedly endemic, species. Bentham

and Hooker reduce the number of genera to thirteen. The forms are very numerous;

but it is very difficult to make an estimate of the number of species. The greater

part of the following names were applied to forms cultivated in European gardens and

described by horticulturists in horticultural periodicals ; and a large number of them

could not possibly be employed in a scientific revision of the family. Many of the

so-called species were founded upon single plants received in a dead state; and the

descriptions are very incomplete. Again, a considerable proportion are simply

characterized by external differences, their flowers never having been seen by the

describers. Doubtless, too, the selfsame forms have often received more than one

name. In some cases no descriptions have been found. However, after making all

due allowances, the species are very numerous; and they find their greatest concen-

tration in Mexico, rapidly decreasing in numbers northward, the extreme limit reached

being about 50° N. lat. In the West Indies the number of species is comparatively

small; but they abound in some parts of Tropical and Subtropical South America, and

a few occur in the temperate regions of Chili. The estimated number of species

under each genus is in all cases taken from Bentham and Hooker (‘Genera Plan-

tarum’); and sometimes their number does not by any means agree with the number of

names enumerated here. The majority of the names are taken up in Walpers’s

‘Repertorium,’ vols. ii. and v., and the ‘Annales,’ vol. ii.

Order LXVII. UMBELLIFER.

Umbellifere, Benth. et Hook. Gen. Plant. i. p. 859.

About 1300 species, mostly herbaceous plants, belonging to about 160 genera. The

order is generally dispersed in temperate and subtropical regions, a few species

extending to frigid regions. In tropical countries it is almost restricted to the

mountains.

. . Tribe HYDROCOTYLE.

There are only seven genera of this tribe, which, with the exception of Hydrocotyle

itself, are restricted to Australia and some of the neighbouring islands and South

America.

2. MICROPLEURA.

Micropleura, Lag. Obs. Aparasol. p. 15; Benth. et Hook. Gen. Plant. i. p. 878.

The only known species :—

1. Micropleura renifolia, Lag. Obs. Aparas. p. 15; DC. Prodr. iv. p. 71.

on the mountains of the Pacific coast of Oaxaca, 6000 to 7000 feet (Galeotti, 2752) ;

GuaTEMALA, Barranca del Incienso (Bernoulli, 289). Hb. Kew.

There seems to be no doubt that the Mexican plant is the same as that described by

Lagasca, though he records it as a native of Chiloe. It also agrees exactly with De

Candolle’s tracing of Mogino and Sessé’s figure quoted above, and should, we think, be

referred to Hydrocotyle.

Tribe MULINEA.

There are nine genera of this tribe, chiefly South-American, but also represented in

South Africa and Australia. There are none in the northern hemisphere, except the

Mexican and one species in the Canary Islands.

parvee, apice 3-dentate ; petala valde involuta, staminibus duplo breviora ; styli erecta. Carpella

(matura non visa) subbialata.

Sourn Muxico, without locality (Bates). Hb. Kew.

A very distinct plant in the Mexican flora, and readily distinguished from its South-

American congeners by its leafy flexuose stem and less laterally constricted carpels.

We have ventured to describe and figure it, although ripe fruit is wanting, because it

is very distinct from all other members of the family hitherto collected in Mexico.

of ripe fruit, it has been thought better to leave them in the genus to which they

are doubtfully referred in Bentham and Hooker’s ‘Genera Plantarum.’ ‘Drawings of

them have been made because they are remarkably distinct from any thing else hitherto
