Order LXX. CAPRIFOLIACE.

Caprifoliacee, Benth. et Hook. Gen. Plant. i. p. 1.

Thirteen genera, comprising about 200 species, are referred to this order. With few

exceptions, they are shrubs or small trees, inhabiting the northern hemisphere. A few

occur in Australia and South America; but the order is not known to be represented

either in Tropical or South Africa. All the Mexican and Central-American species are

shrubby or arboreous.

A genus of upwards of 500 species, generally dispersed in the tropics, but having

their greatest concentration in America. The American species are greatly in need of

revision. We have departed from our practice of giving the unnamed species in Kew

herbarium, because so few of the published names are therein represented by named

specimens, though of the forty or so unnamed species, probably twenty are undescribed.

We have ventured to found this species on very imperfect materials, on account of

its distinct character. It is readily distinguished by its glabrous glaucous stems and

rather large Jeaves in whorls of seven, associated with loose inflorescence, thread-like

pedicels, and a naked somewhat fleshy fruit.

Order LXXII. VALERIANE.

Valerianee, Benth. et Hook. Gen. Plant. 11. p. 151.

Annual or perennial herbs, or rarely shrubby. There are nine genera, embracing

about 300 species, the greater part of which inhabit the temperate and cold regions of

the northern hemisphere and the Andes of South America. A few occur in Brazil,

Guiana, and the West Indies; only one, and that probably introduced, in South Africa ;

in Tropical Asia they are exceedingly rare; and none are known from Australasia.

P. trinervia and P. pilosa in its flower-heads containing only three flowers in an

involucre of three bracts, and in the latter being hairy on the back, as well as in other

details. From P. serrata it differs in its hairiness, foliage, and achenes.

It was not until after the plate had been printed off that we discovered Schultz had

already described this plant under the name of Ageratum microphyllum. We had

overlooked this in consequence of a memorandum in Kew herbarium to the effect that

the plant was not mentioned in the Botany of the ‘Herald.” By a slip in the

‘Genera Plantarum,’ the pappus is described as consisting of ten instead of five pales.

Bentham and Hooker (Gen. Plant. ii. p. 381) refer Mendezia bicolor to Spilanthes ; but

having very carefully examined Coulter and Seemann’s specimens which were referred

to Zinnia, in Kew herbarium, we identify them with Delessert’s figure, and we think it

should be referred to this genus. Coulter and Seemann’s specimens have rather broader

leaves, and are much more branched than the plant figured; but in floral structure

they agree almost exactly. The disk-flowers in Coulter’s specimens are bidentate and

uniaristate, whilst in Seemann’s the awn appears to be always wanting.

probable that several other species enter North Mexico, as they are abundant in the

adjoining parts of New Mexico, Arizona, and California.

197. SENECIO.

Senecio, Linn. Gen. Plant. n. 953; Benth. et Hook. Gen. Plant. ii. p. 446.

As here limited, this is the largest genus in the vegetable kingdom, numbering about

900 species, having nearly the same range as the order, and presenting great variety in

habit and duration. Several species and groups of species have been raised to the rank

of distinct genera by various authors; but we have followed Bentham and Hooker,

though a study of the species from all parts of the world might lead to some useful

division. Perhaps the genus Cacalia might be retained for some of the species ;

yet it is not easy to define it for the Mexican species alone. JS. cervariefolius and some

of the allied species have a somewhat rigid pappus, though in other respects they do

not differ from several others referred by De Candolle and other botanists to

Cacalia.

About 150 herbaceous species, indigenous in the northern hemisphere. Several are

now widely spread weeds of cultivation. The synonymy of the Mexican species has

been very much confused ; and we are unable to correct it. Those we have described as

new are all from the valley of Mexico, and may, one or more of them, turn out to be

introduced plants. .

they resemble each other in the corolla being shorter than the calyx we cannot say, as

we have only seen the corolla of A. calycosa. An analogous species, A. involucrata,

Kurz, occurs in India.

This species bears a striking resemblance to Dipholis salicifolia; but the latter dries

a much darker colour, its leaves are much more attenuated downwards, and its flowers

are smaller on shorter pedicels, and the ovary is quite glabrous. It is not quite certain

that Hahn’s fruiting specimens are the same species as Botteri’s, which are only in

flower.

Nama, Linn. Gen. Plant. n. 817; Benth. et Hook. Gen. Plant. ii. p. 831.

About twenty-two herbaceous and half-shrubby species, inhabiting Mexico and the

neighbouring countries, two extending to South America.

The following synopsis of the Mexican species was kindly furnished by Dr. A. Gray.

All the species of the flora of North America, excepting the peculiar ones of § 2 and

§ 3 of my Synop. Fl. N. Am. ii. p. 175 (i.e. W. lobdii, rothrockit, and parryz), occur in

Mexico, or near its northern line; and the genus mainly belongs to the ‘Texano-

Mexican region. Among the new species which have recently come to hand, and

which are here indicated, are two with appendaged filaments, a character that at first

sight appears to be quite anomalous. But in a considerable number of the species,

including the original V. jamaicense, the adnate base of the filament has more or less free,

thin margins, which are manifestly homologous with the so-called plice or appendages

in the corolla of many Hydrophyllacee, especially in Phacelia and Emmenanthe ; these

are prolonged into a free and conspicuous lobe on each side of the filament in

N. schaffneri, but only into a short tooth in MW. stenophyllum. In NV. palmert the

HYDROPHYLLACE, 361

conspicuously winged margins of the adnate portion of the filament taper upwards, with

no vestige of a tooth.

In Nama there is no hypogynous disk ; but the very base of the calyx is obscurely

adnate to that of the ovary in NV. jamaicense, N. hispidum, &c. It is decidedly so in

NV. undulatum, and so much so in N. stenocarpum that the ovary and capsule appear

to be about one third inferior. The union is complete; but the base of the calyx may

usually be torn away without much rupture. In this species, moreover, is often seen

the anomaly of more or less united styles.

In characterizing the Mexican new species it will be both convenient and useful to

give a synoptical arrangement of all of them now known.

Fruit not seen, and flowers scanty or in poor condition. In two forms—one very

hirsute and hispid, with spreading white hairs; the other with more appressed, some-

what strigose, pubescence, firmer leaves, and more ligneous stems. Appears as if a

denizen of subsaline soil. The appendages of the stamens are as in the foregoing

species, except “the termination, where the filament becomes free, with a short callous

tooth on each side.

N. lodbii, A. Gr., the related Californian species, of which immature fruit is now

found in the Kew herbarium, appears to have only about eight seeds; these oblong,

pendulous, half a line in length, and with a thickish, nearly smooth testa. The

prolonged adnate portion of the filament has distinct, but very narrow, free edges.

N. demissum may have almost as many seeds as WV. palmeri; but it is an annual.

Hb. Kew.

Schaffner and Parry and Palmer have collected characteristic specimens of this species.

The corolla is only two or three lines long, and (as in the figure and description) slightly

surpassing the calyx; and the peduncles are very short. The stock or base is thick and

woody; and even the slender branches become ligneous. Seemann’s 2083, which was

naturally referred to this species, seems rather to belong to WV. rupicolum.

Hb. Kew. .

The original of this species I take to be “WV. rupicola, Pavon,” of which there are

good and quite similar specimens in Boissier’s herbarium and at the British Museum,

formerly in Lambert’s herbarium. As it is Pavon’s name, and as the plant is not found

among the plants of Bonpland in the herbarium at the Jardin des Plantes, I suppose

that Choisy has made a mistake in ascribing the name to the latter. The species has

to be taken in a rather wide sense, even probably to include Seemann’s 2083. The

original specimens are hoary villous, mostly round-leaved, with sepals little shorter

than the corolla, and spatulate-dilated at the tip; the capsule mostly short and small,

as described by Choisy. The specimens from Monterey of Edwards and Eaton have

narrower leaves, much less dilated sepals, and an oblong capsule. And the following

very marked form must be added :—

Var. rotundifolium, A. Gr.

Viride, pilis tenuibus interdum longis subviscosis villosum; pedunculis plerisque elongatis fili-

formibus ; sepalis corolla (lineas 4 longa) dimidio brevioribus ; capsula aut ovali aut oblonga.

Norta Mexico, near Monclova, Coahuila (Palmer, 983), near Monterey (Palmer, 984) ;

Souto Mexico, Cuernavaca (Bilimek, 392). Hb. Kew.

There are two forms. Palmer's 983 is remarkably green and large-leaved, probably

from growing in moist and shady situations; 984 is villous, with very soft long hairs.

Bilimek’s 392 connects this with the genuine NV. rupicolum.

tt Folia fere sessilia, opposita.

8. Nama serpylloides, A. Gr., n. sp.

Puberulum, effuse ramosissimum, gracile; foliis spathulatis vel obovatis basi attenuatis fere eveniis

The fine pubescence is seemingly somewhat viscid; and the long villous or hirsute

hairs so common in related species are wholly wanting. ‘he leaves appear to be

uniformly opposite!

Meissner (FI. Bras. vii. p. 219) was not at all clear as to the limits of this species

and J. dlaveana, and suggested that they might be the same, besides making a third

(I. hartwegit) of the true I. peduncularis. He was perhaps misled by Lindley’s figure

in Journ. Hort. Soc. v. p. 83, which represents J. dlaveana. At all events the two

species are very distinct. J. peduncularis has smaller flowers than the other, the tube

of the corolla being relatively short and straight, and the lobes of the limbs of the

corolla relatively long and narrow. The stamens, too, are much more exserted than

those of I. llaveana.

| Order XCV. SOLANACEZ.

Solanacee, Benth. et Hook. Gen. Plant. ii. p. 882.

Herbs or shrubs, rarely arboreous, generally dispersed in warm and temperate regions,

The Order contains sixty-six genera, embracing about 1250 species, according to

Bentham and Hooker’s calculation, and upwards of 1800 species according to Dunal

and Miers.

1. LYCOPERSICUM.

Lycopersicum, Mill. Dict., ex Benth. et Hook. Gen. Plant. ii. p. 888.

Three or four herbaceous species indigenous in Tropical America, commonly culti-

vated and now naturalized in many other parts of the world.

p. 26; A. Gr. Synop. Fl. N. Am. ii. p. 226.

Common in Mexico and Central AMERICA, as well as in other parts of TROPICAL

AMERICA and the West InvigEs; but it is difficult to determine where it is really

indigenous and where it is only naturalized. Hb. Kew.

2. SOLANUM.

Solanum, Linn. Gen. Plant. n. 251; Benth. et Hook. Gen. Plant. ii. p. 889.

Herbs, shrubs, or small trees, chiefly inhabiting tropical and subtropical regions, and

especially numerous in America; a few occur in temperate regions, both north and

south. Upwards of 900 species have been described; but a thorough revision would

doubtless result in a considerable reduction of the number.

The unnamed species of Solanum in Kew herbarium from Mexico and Central

America are numerous, and include doubtless some undescribed ones, as well as most

of those enumerated below.

cultivated varieties. |

Foliis glabris lanceolato-oblongis, floribus mediocribus puberulis, corolla anguste campanulata

insigniter nervosa, staminibus basi coroll insertis.

Frutex epiphytus?, ramulis pedunculisque tuberculatis, scabridis vel fere muricatis. Folia alterna,

petiolata, coriacea, glabra, lanceolato-oblonga, 4-6 poll. longa et usque ad 14 poll. lata, longe

acuminata, obtusiuscula, basi seepius rotundata, margine obsolete undulata, venis primariis

mentis basi leviter barbatis ; ovarium glabrum, leve, stylo sursum clavato. Fructus deest.

Costa Rica, without locality (Endres, 534). Hb. Kew.

The strongly nerved corolla is remarkable; and, should it be associated with any

peculiarity in the fruit, this species might form a new genus.

2. Markea, sp.?

Dunal (DC. Prodr. xiii. 1, p.’ 528) refers Galeotti’s 1112 to J. parasitica, citing

Mart. et Gal. in Bull. Acad. Brux. xii.; but the number there given is 1202, and the

name quoted is J. aurantiaca. Galeotti would be likely to know the latter, as it was

in cultivation at the time.

Bentham and Hooker (Gen. Plant. ii. p. 908) limit the genus Bouchetia to one

species, and identifying, erroneously as we believe, Galeotti’s 1476 and Bourgeau's 68

with B. procumbens, refer that to Mierembergia. The specimens we have referred to

this species are, like those of B. erecta, easily distinguished from any Merembergia by

the gradually tapering tube of the corolla, and by the longer, perfectly free stamens

inserted lower in the corolla.

Bentham and Hooker (Gen. Plant. ii. p. 908) refer Galeotti’s 1476 and Bourgeau’s

68 to Bouchetia procumbens, DC., which, however, is a distinct plant, and, as we believe,

a true Bouchetia: see our remarks under that genus.

Leptoglossis (Brachyglossis) coulteri, A. Gr. in Proc. Am. Acad. xii. p. 165.

SoutH Mexico, Zimapan (Coulter, 1346). Hb. Kew.

We regret being unable to follow Dr. Gray in referring this and the next to Lepto-

glossis, this especially being so like a typical Nierembergia as not to be easily distin-

guished from such species as N. veitchii, Berkeley in Bot. Mag. t. 5599, and WV. filicaulis,

Lindl. Bot. Reg. t. 1649. Moreover the typical species of Leptoglossis are so different

in habit, and in the form of the corolla, that we regard the character derived from the

stamens as of secondary importance, particularly as some other species of Merembergia

exhibit a tendency to inequality in the size and degree of development of the stamens.

Although this is very closely allied to Castilleja sessilifiora, we have preferred placing

it in Orthocarpus, because it certainly ought to go into the same genus as O. australis,

and because it differs from nearly all the species referred to Castilleja in the bifid lobes

of the calyx, and in the long exserted corolla with nearly equal lips. Perhaps it would

be better to place Castilleja sessiliflora and one or two allied species in Orthocarpus.

tubiflora, H. B. K.), which is described as having solitary, axillary flowers; and at

the same time suggested that D. leucanthus, Nees, was the same species. We have

the type of the latter before us; and it offers most striking differences in its large calyx

no authenticated specimens before him, for it is a very distinct species. A. thurberi, of

whereof two genera and sixty-eight species are Australian; one genus extends from

New Zealand to the Pacific, Mascarene and Malayan Islands, China and Japan ;

another, of two species, is peculiar to South Africa; and the monotypic Bontia

(B. daphnoides, L.; Griseb. Fl. Brit. W. Ind. p. 503) inhabits Trinidad, Antigua, Hayti,

and other islands in the West Indies. The Se/aginew number eight genera and about

140 species. Six of the genera and about 120 of the species are peculiar to South

Africa, with the exception of one species found in Madagascar. Of the two remaining

genera, one inhabits the Mediterranean region, including the Canary Islands, and the

other Central and North Asia. |
