SERRURIA FLORIDA.

Cape Province.

Proteaceae. Tribe Proteeae.

Serruria, Salisb. ; Benth. et Hook. f. Gen. Plant, vol. iii. p. 170.

Surruria florida, Knight, Prot. 92; FI. Cap. vol. v. sect, i, p. 678.

This species of Serruria has always been regarded as the

most beautiful in the genus, and justly so, as the “ flowers ”

are certainly extremely handsome. The plant was first

found by Thunberg in the mountains round Franschhoek,

and was then lost sight of for about 100 years, when it was

re-collected by the late Prof. P. MacOwan. While the in-

florescence is so striking, the plant itself is rather disappoint-

ing, as it is a lanky shrub up to 12 ft. high and not at all

pleasing in shape. Serruria florida is known as the “ Blushing

Bride ” or the “ Trots van Franschhoek.” On account of the

very restricted distribution of the species, a few years ago

there was much concern about the danger of its becoming

extinct owing to mountain fires. But recently it has been

successfully cultivated at the National Botanic Gardens,

Kirstenbosch, and there attracts special attention when in

flower. We are indebted to Mrs. J. C. Letty for specimens

which she sent from Franschhoek and from which our Plate

was prepared.

Description : — A tall lax shrub. Branches yellow, red

in patches, glabrous. Leaves about 10 cm. long, pinnately

and bipinnately divided from 1-2 cm. above the base, glabrous ;

ultimate branches channelled on the inner face, acutely

mucronate. Heads peduncled, solitary or 2-4 in a sub-

corymb at the ends of the branches. Peduncles up to 5 cm.

long, with a few linear-lanceolate bracts up to 1*5 cm. long,

glabrous. Bracts whitish, flushed with pink, surrounding

the inflorescence up to 3-5 cm. long, and 1-2 cm. broad,

oblong-elliptic, acuminate, overtopping the flowers. Floral

bracts 2 cm. long, 4 mm. broad, linear-lanceolate, tapering

to a long acuminate point, long white-villous on the lower

half on back, long ciliate. Calyx-tube 2 mm. long, glabrous;

segments 6 mm. long, glabrous; limb 3 mm. long, oblong-

linear, thinly villous with long hairs ; the posticous limb with

a few short hairs. Anthers 2 mm. long. Ovary villous, sur-

rounded by long hairs; style 8 mm. long, with a globose

swelling at the base, glabrous. (National Herbarium,

Pretoria, No. 10,854.)

Worcester distr. : from the Caledon Show, collected between Worcester and

Villiersdorp. Donated by Mr. T. P. Stokoe in National Herbarium, 10,859

(type).

It seems surprising that this handsome species of Surruria,

which grows in frequented localities, should have remained

unknown for so long. The first record we have is a specimen

collected by the late Dr. R. Marloth at Franschhoek in

October 1916. Mr. T. P. Stokoe sent us specimens from the

Caledon Wild Flower Show in September 1931, and Mrs. J. C.

Letty collected specimens both at Franschhoek and at

Hopefield in the Malmesbury district.

The species is closely allied to Surruria florida, which is

figured in Plate 481, but differs in having rosy bracts sur-

rounding the inflorescence, and the bracts subtending the

flowers are not produced into long acuminate tips which much

overtop the flowers.

The specific name has been chosen on account of the rosy

bracts.

Our illustration was prepared from a specimen sent by

Mr. T. P. Stokoe, which has been made the type of the

species.

Description : — Branches yellow stained with brilliant red,

terete, glabrous. Leaves 3-6 cm. long, bipinnately divided

in the uppermost f , glabrous ; ultimate segments about 1 cm.

long, terete, acutely mucronate. Heads peduncled, 2-2-5 cm.

long, 2-3 cm. in diam., 4-9, arranged in a sub-corymb at the

ends of the branches. Peduncles with a few scattered ovate-

lanceolate acuminate bracts, glabrous. Bracts surrounding

the inflorescence 1 -5-2-5 cm. long, 0-6-1 -4 cm. broad, ovate to

lanceolate, acuminate, more or less pustulate on the back.

Floral-bracts pink, 1 cm. long, lanceolate, acuminate, densely

white-villous. Calyx-tube 3 mm. long, surrounded by a dense

mass of long white hairs, glabrous; segments 1 cm. long,

villous on the uppermost portion, otherwise glabrous; limb

2-5 mm. long, oblong-elliptic, with the posticous one sparsely

villous and the other three densely long-villous. Anthers

2 mm. long. Ovary villous; style 1 cm. long, glabrous;

Hypogynous scales 3 mm. long.

Transvaal : Pilgrim’s Rest distr. : Mount Anderson, near Sabie, June

1932, Smuts 44 and in National Herbarium, 12,942.

The species of Helichrysum figured and described is very

distinct. It was found on the summit of Mount Anderson at an

altitude of 7300 ft. above sea-level. The plant grows to a height

of 3 ft. and forms a shrub several feet in diameter. The silvery

leaves and pinkish heads make it a very conspicuous object

in the veld. The type of branching is rather peculiar, as each

branch divides into three short branchlets, each of which

terminates in a flower-head. We are indebted to General

the Rt. Hon. J. C. Smuts, F.R.S., for the specimens illustrated.

Description : — A shrubby plant up to 1 m. high. Stems

woody, 2-5 cm. in diam., branching at the apex into several

densely leafy branches which usually divide again at the

apex into 3 branchlets, each of which terminates in a capi-

tulum. Leaves 3 cm. long, 1-5 cm. broad, oblong, strongly

reflexed, with revolute margins, and with the apices recurved

and mucronate, distinctly 3-nerved, densely yellowish-white,

woolly beneath, shortly and densely pubescent with gland-

tipped hairs above. Capitula 2 cm. long, about 3 cm. in diam.

Involucral bracts in many rows, lustrous, white with deep rose

tints, 5-15 mm. long, 3 mm. broad, ovate to linear-oblong,

obscurely and minutely mucronate at the apex, which some-

times splits into 3 teeth. Receptacle nude, minutely honey-

combed. Florets numerous, greenish-yellow. Pappus of few

glandular bristles.

Scrophttlariaceae. Tribe Manuleae.

Sutera, Roth. ; Benth. et Hook. f. Gen. Plant, vol. ii. p. 945.

Sutera aurantiaca (Burch.) Hiern in Cat. Afr. PI. Welw. i. p. 757 ;

FI. Cap. vol. iv. ii. p. 292.

Sutera aurantiaca is a widely distributed species in South

Africa, and extends into tropical Africa. Burchell, in his

Travels in South Africa, first described the plant as Buchnera

aurantiaca, and Hiern took over the specific name. At

Fauresmith, in the Orange Free State, where the plant was

collected, it grows in masses in grassy depressions near streams.

When in bloom the small bright flowers make the plant a very

attractive object. We are indebted to Miss I. C. Verdoorn for

the specimens figured.

Description : — Stems many from a woody rootstock,

radiating, spreading on the ground and ascending, slender,

terete, thinly and shortly glandular-pubescent. Leaves

fascicled, up to 1 cm. long, bipinnatisect, with the seg-

ments obovate-oblong or linear, shortly glandular-pilose.

Flowers orange-vermilion in colour, axillary or sometimes

racemose at the ends of the branches. Pedicels up to 2 cm.

long, shortly glandular-pilose. Calyx deeply 5-lobed, c. 3 mm.

long, shortly glandular-pilose ; segments linear-spathulate.

Corolla-tube about 7 mm. long, tubular, slightly widened

and curved near the top, sparsely and shortly glandular-

pilose without; lobes 5, spreading, slightly unequal, broadly

oblong to almost rotund. Stamens included, inserted in the

corolla-tube. Style up to 6 mm. long; stigma terminal.

Orange Free State : Fauresmith distr. : Veld Reserve, on slopes and

at foot of Koppie, Verdoorn 1053 (type), 990; Henrici 1803; Smith 3962,

5291, 5406, 4526.

On Plates 131 and 196 we figured species of the genus

Sutera. The genus is typically South African, as the majority

of the species (about 118) are found in the Union, only a few

being recorded from tropical Africa, and one species has been

found in the Canary Islands. The species we describe and

figure falls into the same section of the genus as that previously

illustrated. In the Fauresmith district the species is found

on the slopes and at the foot of Koppies and also in the open

veld. It is readily eaten by all grazing animals, and the

constant grazing may probably cause the stunted woody

base of the plant which is so characteristic. The new growth,

which is herbaceous, is also somewhat aromatic. We are

indebted to Miss I. C. Verdoorn for the specimens figured.

Description : — A small bush 15-45 cm. high, with a

thick woody tap-root. Branches very slender, densely and

finely glandular, herbaceous, becoming woody with age.

Leaves opposite, sometimes fascicled, 0-5-1 *3 cm. long, linear-

oblanceolate to obovate, entire, or toothed or lobed at the

apex, densely and finely glandular. Flowers few to many,

arranged racemously on the ultimate branchlets. Bracts

resembling the leaves, but smaller. Pedicles 0-5-1 -2 cm.

long; erect, slender, glandular. Calyx 5-lobed to the base;

lobes about 2 mm. long, linear, finely glandular. Corolla-

tube faintly suffused with purple, 6-9 mm. long, usually more

than twice as long as the calyx, slender, with a slight oblique

gibbosity at the throat, glandular-pubescent; limb 2-lipped,

spreading; lobes white, with slender purple markings

at the base, strape-shaped, emarginate. Capsule small,

membranous.

(types).

The species of Euphorbia which we figure and describe

is quite distinct from E. tetragona Haw., which belongs to the

same section of the genus as our plant. Its affinities are with

some of the tropical African species of Euphorbia and it is

very closely related to a plant collected by the late Dr. R.

Marloth at Lobatsi in Bechuanaland, which Pax described

as E. griseola. We are indebted to Messrs. J. C. van Balen

and G. J. de Wyn for the specimens. In the locality in

which they were collected the species is common and grows

socially.

Description : — An erect fleshy spiny shrub up to 44 cm.

high, branched from the base. Branches ascending, up to

1-2 cm. thick, often 4-angled, glabrous, with the faces usually

concave; shields on the angles about 1 cm. long, continuous,

with 2 large and 2 very small spines. Larger spines 5-7 mm.

long, diverging and horizontal; smaller spines about 1 mm.

long. Bracts 1 mm. long, 1-5 mm. broad, ovate, acute,

glabrous. Cymes in groups of 3 cyathia, axillary, sessile.

Cyathia 2-5-3 mm. in diameter, with 5 entire transversely

oblong glands and 5 ovate irregularly-toothed lobes; the

middle cyathium male, the lateral bearing male and female

flowers. Ovary included, sessile, glabrous ; styles 3, spreading

and reflexed. Capsule 2 mm. long, 3 mm. diameter, 3-lobed,

sessile. Seeds (immature) tuberculate.

The genus Lycium is represented in South Africa by about

18 species, all of which are spiny shrubs. About 50 species

of the genus have been recorded from the temperate and

warm regions of the world ; and it is very common in South

America. The South African species very much need critical

revision, as many of them, despite the thorny habit, are eaten

by small stock. The species described and figured makes a

beautiful show when in full bloom. It is fairly common on

the farm Varkfontein in the Fauresmith district, where it

was found flowering in an open stretch of brackish soil in

November 1932. Farmers report that the young shoots are

eaten by sheep and the plant is considered to be a good

grazing shrub.

Mr. C. A. Smith notes on a sheet ( Smith 490) “ a perfect

match of Burchell 1514, from the Zak Rivier, Aug. 13, 1811,

Faserburg div. and referred by Wright (FI. Cap. iv. ii. 113) to

L. oxycarpum var. parviflorum .” We have no authentic

specimens of this species but according to the description the

plants differ from L. oxycarpum in having exserted stamens

which are inserted just below the middle of the corolla-tube.

We are indebted to Miss I. C. Verdoorn for the specimen

figured.

Description : — A shrub 1-3 m. or more high, with erect

stems and long, widely spreading branches. Branches pur-

plish-brown, with a silvery sheen, glabrous; the ultimate

branches about 7 cm. long, divaricate, ending in a spine.

Leaves fascicled, unequal in length, up to 1 cm. long and

2 mm. broad, oblong-cuneate. Pedicel solitary from the

centre of the fascicle of leaves, up to 1 cm. long, filiform,

thickening towards the apex. Calyx cup-shaped, 4 mm.

long, shortly 5-toothed ; teeth somewhat unequal and

evidently puberulous along the margin. Corolla campanu-

late-funnel-shaped, 7-8 mm. long, up to 1-4 cm. in diara.,

when fully expanded; lobes 5, rarely 4, about 4 mm. long,

ovate to oblong, spreading. Stamens 5, rarely 4, inserted

just below the middle of the corolla-tube, exserted ; filaments

slightly unequal, densely villous at the thickened base.

Transvaal : Zoutpansberg distr. : near Waterpoort on farm Chapudi

141, near the house of Mr. Booysen, Obermeyer, Schweickerdt, and Verdoorn,

We have on several occasions illustrated species of the

genus Ceropegia and that shown on the accompanying plate

should be compared with these. Our species is nearest

C. stapeliaeformis Haw., which is figured in the Botanical

Magazine, t. 3567. Both have fleshy stems, but in C. stapeli-

aeformis the flower-bud is produced into a beak, whereas in

C. cimiciodora the flower-bud is more or less flattened at the

apex. Although of unattractive habit the flowers are

beautiful. In its native habitat it was found scrambling in

a small thorn bush 3 ft. high. It grows in sandy soil, and is

evidently extremely rare in the locality where it was collected.

We are indebted to Mr. G. van Son, who grew the plant in

Pretoria. It was from this specimen that our plate was

prepared and the description made. The specific name has

been given because the flower emits an odour of a bedbug

(Cimex sp.).

Description : — Stems fleshy, tuberculate, shiny, greyish

mottled with olive green, glabrous. Leaves sessile, 2-5 mm.

long, 3 mm. broad, cordate or triangular. Flowers solitary

or two together developing successively on the shortened lateral

branches. Pedicels 8 mm. long. Sepals 2 mm. long, narrow-

ovate. Corolla mottled grey and speckled with purple at the

apex, c. 5 cm. long, curved ; tube with a small white ring at

the base, inflated at the base and there gradually narrowed

and cylindric, funnel-shaped at the mouth, glabrous without,

softly pilose within at the base and at the mouth ; limb star-

shaped when viewed from above, 2 cm. diam. ; lobes not

connate at the apex, ciliate, tips indexed, replicate and pro-

duced beneath into keels ; in bud the flower forms a 5-rayed

star-shaped structure when seen from above, with each ray

broadly triangular and shortly acuminate. Outer corona-lobes

erect, with 2 teeth and sometimes an irregular smaller one,

pilose with long white hairs on the inside and on the margin ;

inner corona-lobes 4 mm. long, incumbent over the backs of

the anthers and then connivent into an erect column with

shortly recurved tips, dorsally connected to the outer corona

at the base and there with twro brown vertical stripes.

Follicles 10 cm. long, tuberculate and with knob-like apices.

vol. vi. p. 366.

We have previously figured two species of Bulbine (see

Plates 217 and 377). The species illustrated on the accom-

panying plate belongs to quite another group of the genus as

a comparison of the Plates will show. While the species

differ so in habit, as, for example, B. latifolia with its broad

leaves, and B. mesembryanthemoides with its peculiar leaves

partly buried in the ground, all agree in having stamens with

hairy filaments. The genus as a whole is not particularly

attractive, but as it is typically South African, we take the

opportunity of figuring any species which come into flower.

B. latifolia was illustrated over 140 years ago by Jaquin, though

the plate is not very typical of the plant as it grows naturally.

Our specimen was grown in the garden of the Division of Plant

Industry, Pretoria, and was collected near Drummond in

Natal by Mr. J. J. van Nouhuys.

Description : — An acaulescent perennial with a dense

rosette of leaves. Leaves fleshy, varying in number up to 20,

up to 30 cm. long, 5-6 cm. broad at the base, ovate-lanceolate,

acuminate, with narrow membranous margins and reticulate

veins, glabrous. Peduncle up to 32 cm. long, about 4 mm.

in diam. Flowers in a raceme; on the lower part of the

peduncle scattered, becoming denser above, maturing suc-

cessively, the lowest flowers fall while the uppermost are still

in bud. Bracts 3*5 mm. long, ovate, long-acuminate.

Pedicel up to 1 cm. long, articulating at the apex, typically

securved after flower has fallen. Perianth 7 mm. long;

regments linear. Stamens 2-5 mm. long; filaments covered

with long hairs; anthers 0-75 mm. long, sub-globose. Ovary

0-75 mm. long; style 4’5 mm. long; stigma sub-capitate.

Orphium frutescens, E. Mey., Comm. 181 ; FI. Cap. vol. iv. sect. 1. 1095.

The genus Orphium, which contains only one species, is

endemic to the south-western districts of the Cape Province.

It is one of the components of the true strand flora, and Dr.

J. Muir ( The Vegetation of the Riversdale Area ) mentions it as

one of the commonest plants of the halophilous marshes of

the strand veld. The plant varies considerably in habit

according to the conditions under which it grows; those of

the shore have broader, thicker leaves crowded on the stem,

while in the inland forms the leaves are narrower, thinner

and not so crowded. We are indebted to Mrs. J. C. Letty for

the specimens which were collected near the sea at Saldanah

Bay in 1926.

Description : — A shrub 15-100 cm. high, much-branched.

Leaves opposite, decussate, 2-5-5 cm. long, 0-4-1 cm. broad,

flat, oblong-lanceolate or lanceolate or sub-linear, obtuse or

sub-acute, usually villous-pubescent. Flowers pedicelled,

solitary or in 3-5-flowered cymes. Calyx 1-2 cm. long,

divided half-way, pubescent without; lobes obtuse, rarely

sub-acute. Corolla-tube as long as the calyx, narrowly

fusiform; lobes 2 cm. long, 1-1-2 cm. broad, obovate, obtuse.

Stamens inserted in the throat of the corolla; filaments

flattened at the base; anthers linear-oblong, twisted. Ovary

6 mm. long, 1-chambered, ovoid-oblong, with intruding

placentas and numerous ovules ; style filiform ; stigma

capitate.

Disa rhodantha, Schltr. in Engl. Bot. Jahrb. vol. 20, Beibl. 50, 40 ;

FI. Cap. vol. v. sect. 3, p. 229.

This beautiful species of Disa is found at the higher

altitudes of the Transvaal and on the mountains of Griqualand

East and Natal. It appears to be confined to swampy

places. The species falls into a section of the genus in

which the numerous flowers are arranged in a more or less

dense elongated spike. As mentioned in a previous descrip-

tion, D. rhodantha is another of those Transvaal orchids which

have remained unfigured owing to difficulties in transporting

living specimens long distances.

Mr. E. E. Galpin, F.L.S., to whom we are indebted for

sending in fresh specimens, collected the plants in swampy

ground on the bank of the Crocodile River, near Dullstroom

in the eastern Transvaal.

Description : — Plant 54 cm. high. Stem robust. Leaves

radical and cauline ; radical leaves 5, spreading, 25 cm. long,

3 cm. broad, lanceolate or linear-lanceolate, acute; cauline

leaves 10 cm. long, distinctly stem-clasping, with the free

portion spreading. Inflorescence a dense many-flowered spike

up to 20 cm. long. Bracts 2 cm. long, lanceolate, acuminate.

Flowers rose-coloured ; dorsal sepal 4 mm. long, galeate, with

a minute apiculus at the apex situated at about 1 mm. from

the edge ; spur cylindric from a conical base, much longer than

the limb, curving forward and then backwards and upwards ;

lateral sepals 8 mm. long, 4 mm. broad, somewhat oblique,

with a short stout dorsal apiculus. Lateral petals 6 mm. long,

slightly oblique, oblong-lanceolate, acute ; lip sometimes light

yellow, sometimes greenish-purple, 6 mm. long, linear -

spathulate. Column white, short; rostellum emarginate or

shortly bilobed, with very short side lobes; stigma roundly

and bluntly hexagonal ; anthers almost horizontal. (National

Herbarium, Pretoria, No. 14,511.)

Satyrium ocellatum, Bolus ; Ic. Orch. Austro- Afr. vol. i, tab. 23,

ex parte ; FI. Cap. vol. v. sect. 3, p. 166.

This is the first opportunity we have had of figuring a

species of Satyrium. The genus Satyrium is represented by

about 100 species, over half of which occur in South Africa,

mostly in the south-western and eastern districts of the Cape

Province. The species recorded from the Orange Free State

and the Transvaal are from the eastern mountain range. The

possible exception is the species we illustrate, which has been

collected in the neighbourhood of Johannesburg and Pretoria.

The species of Satyrium are readily distinguished from

species of Disa in the flower having two spurs. The plants

from which our Plate was prepared were found by Mr. A. 0. D.

Mogg, M.A., in marshy ground at Pyramids Vlei near Pretoria.

In this locality the plant was plentiful.

Description : — Plants varying from 35-70 cm. high.

Stem simple. Leaves cauline, decreasing in size up the stem,

distinctly stem-clasping, with the free portion of the lowest

leaves up to 18 cm. long, 4 cm. broad, lanceolate, subacute,

distinctly nerved below. Inflorescence up to 16 cm. long.

Bracts reflexed, 2-5 cm. long, 8 mm. broad, lanceolate, acute,

glabrous. Flowers white or pale pink. Sepals 9 mm. long,

4 mm. broad, obovate-oblong, with the anterior petal linear

and narrower than the lateral ones. Lateral petals similar to

the sepals but narrower; lip superior, 1 cm. long, galeate;

spurs 3 cm. long, gradually narrowing downwards. Column

1 cm. long, slightly curved ; rostellum more or less ovate, with

2 small side-lobes; stigma slightly convex. Anther-sacs

pendulous under the rostellura ; pollinia granular, 2-lobed.

Lissochilus Sandersoni, Reichb. f. Otia Bot. Hamb. i. 62. Eulophia

porphyroglossa, Bolus in Journ. Linn. Soc. vol. xxv. p. 185.

Between genera so closely allied as Lissochilus and Eulophia

it is difficult to state the differences except in general terms.

They were created at the same time by R. Brown, who

distinguished Lissochilus from Eulophia by its uncrested, or

more strictly speaking unbearded, lip ( lissos — smooth;

cheilos = lip), reflexed sepals, and broader and more erect

petals. When all these characteristics are combined in the

same flower, they afford sufficient ground for upholding

Lissochilus, and the difficulty of decision arises only in the

case of intermediate forms. The question of uniting the two

genera has been fully discussed, and some fifty years ago,

when the matter was referred to the authorities at Kew, the

decision given was that “ there appear to be no good grounds

for separating Lissochilus from Eulophia ; the character of

the broad petals as a distinctive mark of Lissochilus breaks

down, and the character of an uncrested lip, upon which

Brown founded the genus Lissochilus, equally so.” In 1913,

however, when the late Mr. Rolfe’s monograph was published

in the Flora Capensis both genera were upheld, Lissochilus

comprising the thirteen non-controversial species and the

controversial ones being retained in Eulophia. Since then a

certain amount of living material has been handled, and the

impression made is that the more robust habit, apart from

actual size, the more leathery leaves, broader sepals and petals,

and the more fleshy and solid nature of the crest (it is mis-

leading to call the lip “ smooth ”), which is not finely divided

into hair-like segments, constitute generic significance. All

these characteristics are exhibited in Lissochilus Sandersoni,

one of the handsomest of the South African Orchidaceae, whose

range extends from Natal into tropical Africa. The specimen,

of which a portion is figured here, was sent by Dr. J. W. Bews,

probably from near Durban, in November 1916. The leaf

drawn is reduced to half the natural size.

Description : — Leaves 3-4, up to 1-2 met. long, 8-10 cm.

broad, narrowed downwards into a petiole, prominently

veined. Scape 1 met. high, up to 1-6 cm. diam. ; sheaths few,

acute, 4-7 cm. long. Raceme 20 cm. long, rather dense, many-

flowered. Bracts broadly ovate or suborbicular, cuspidate,

3-1-5 cm. long. Pedicels in fruit about 5 mm. long. Sepals

spreading or reflexed, oblong-obovate, shortly acuminate,

2- 5 cm. long. Petals oblong-ovate or orbicular-ovate, obtuse,

up to 3 cm. long, 1 -5-2-1 cm. broad. Lip inferior, with the

broadly conical spur 7 mm. long up to 4-5 cm. long, up to

3- 5 cm. broad, with 3 rows of conspicuous papillae extending

from the base to the middle of the intermediate lobe, con-

spicuously 3-lobed, the side-lobes erect, anrple rounded, inter-

mediate curved upwards, oblong-orbicular, up to 1-7 cm. long,

1-5 cm. broad. Column 1-8 cm. long, produced at base into a

distinct foot; anther 2-horned at the apex; gland trans-

versely elliptical. L. Bolus. (Bews; Wood 374.)

(1921) ; Platanthera tenuior Schltr.; FI. Cajp. vol. v. sect. 3, p. 88.

In the year 1865 the plant we figure was described by

Reichenbach as a species of Brachycorythis ( B . tenuior).

Twenty years later Dr. N. E. Brown transferred the species to

the genus Habenaria and in 1895 Schlechter referred it to the

genus Platanthera. The late Dr. H. Bolus accepted this name

and figured the species in Orchids of South Africa (PL 61) as

Platanthera tenuior , Schltr. In the Flora Capensis published

in 1913 the name was also kept up by Rolfe. In 1921 Schlech-

ter proposed the name Diplacorchis for several species and

included our plant under this new genus. Apparently the

only difference between the genus Platanthera and Diplacorchis

is that species of the latter have a bilobed lip.

The specimen we figure was collected by Mr. J. J. van

Nouhuys, B.Sc., among grass on the hilltops between Ashbury

and Zwartkop Aerodrome near Pretoria.

Description : — A glabrous herb 30 cm. high. Tubers

finger-like, 3-5 cm. long, -8-1-2 cm. in diam., irregular.

Leaves cauline, passing into sheaths below and bracts above,

sessile, 4 cm. long, 2 cm. broad, ovate-lanceolate, distinctly

keeled, with a more or less prominent vein on each side of the

mid-rib, obtuse. Bracts similar to the leaves but smaller.

Ovary 1-2 cm. long, twisted, with deep channels and rounded

ridges. Sepals 7 mm. long, obliquely lanceolate, subfalcate.

Petals slightly smaller than the sepals; lateral petals 7 mm.

long, 4 mm. broad, ovate, obtuse, somewhat concave ; posterior

petal with the 2 lateral sepals forming a partial hood. Lip

adnate to the column; limb 9 mm. long, 7-5 mm. broad,

obovate, bilobed, with crenate margins; spur 6 mm. long,

obtuse. Anther-thecae erect ; pollinia glandular, each attached

to a separate caudicle and gland ; glands naked, lying on the

lateral arms of the rostellum. Rostellum shortly 3-lobed ; the

middle lobe strongly laterally compressed and lying between

the 2 anther-thecae, longer than the lateral lobes. (National

In the past it has been extremely difficult to illustrate the

Transvaal orchids in colour on account of the difficulty of

sending fresh material to Cape Town where the late Dr. H.

Bolus worked on his Orchids of South Africa. Now that we

have an opportunity in Pretoria of figuring living plants we

hope to illustrate most of the orchids. The specimens illus-

trated on the accompanying Plate were forwarded to us in

January 1933 by Mr. E. E. Galpin, F.L.S., who found them

growing on rocks on Suikerboskop, at an altitude of 7000 ft.,

near Dullstroom in the eastern Transvaal. Disa saxicola is

closely related to D. oreophila, Bolus, which is found in the

eastern districts and Natal. It differs in having broader leaves

and differently coloured flowers. It has been recorded only

from the Transvaal in South Africa, but has also been collected

in tropical Africa.

Description : — A rather slender plant 20 cm. high.

Leaves 5, cauline, spreading and arching, 15 cm. long, 8-12 mm.

broad, linear or linear-lanceolate, acute, glabrous. Inflores-

cence 6 cm. long, somewhat lax, many-flowered. Bracts

•7-T2 cm. long, 2 mm. broad. Flowers white with bluish-

purple spots. Dorsal sepal hood-shaped, 4 mm. long, broadly-

ovate, obtuse ; spur cylindric from a conical base, longer than

the limb and curving downwards ; lateral sepals 5 mm. long,

broadly oblong, obtuse with a blunt apiculus. Petals included

under the dorsal sepal, 3 mm. long, broadly wing-like, dilated

at the base in front; lip 3 mm. long, linear-spathulate.

Column short, anthers almost horizontal ; pollen-sacs spotted

with purple ; rostellum erect, shortly 3-toothed ; stigma

thickened. (National Herbarium, Pretoria, No. 14,512.)

vol. iii. p. 535.

Eulophia MacOwani, Rolfe in Dyer, Flor. Cajp. vol. v. sect. 2, 38.

The specimen figured here was collected by the late Mrs.

Mildred A. Holland near Frames’ Drift, a few miles from Port

Elizabeth, in February 1917, and represents a plant of normal

size. A recent (January 1932) collection by Mr. F. H.

Holland from the plateau above Bushman’s River Mouth,

after good rains, has slightly larger flowers whose measurements

are included in this description. The rhizomes of the latter are

remarkable in being up to 45 cm. long. The species belongs

to the group which has the leaves and flowers developed con-

temporaneously. The ovary appears to remain untwisted

throughout the flowering, and in consequence the lip retains

the superior or posticous position and the odd sepal is inferior

or anticous in the flower, which is among the largest in the

genus.

It is possible that the inland localities cited in the Flora

Capensis for E. MacOwani may prove to belong to other

species. For example, Tyson 1086 from near Kokstadt is

quoted both under E. MacOwani and E. robusta, and it is

certainly better placed under the latter ; so that E. MacOwani

may be said usually to haunt sandy localities near the mouth

of rivers : it also occurs at the Kowie and Keiskamma Rivers.

Besides being confused with E. barbata and E. robusta, this

species has also been taken for E. Dregeana, as, for example, in

the leones Orchidearum, ii. t. 9, where the two plants dealt

with are probably E. barbata and E. MacOwani, as Mr. Rolfe

suggested.

Description : — Rhizome elongated ; pseudobulbs up to 21,

up to 4 cm. diam. Leaves 7, erect or finally spreading, con-

duplicate, linear, acuminate, veins conspicuous with age, 1-2

primary veins prominent on each side of the midrib, texture

rather thin, 6-20 cm. long, 1 -4-0-8 cm. broad. Scape 30-40

cm. high, up to 5 mm. diam. ; sheaths 5-7, up to 6 cm. long,

the lower imbricate. Raceme 8-16 cm. long, simple or very

rarely with a branch from the lowest bract, 10-14-fl. Bracts

broadest near the middle, acute or acuminate, 2-1-1 cm. long.

Pedicels differentiated from the ovary in fruit up to 8 mm. long.

Sepals spreading, linear, acute or acuminate, up to 2-5 cm.

long and 7 mm. broad. Petals oblong-elliptic or subobovate,

obtuse or abruptly acute, up to 2-8 cm. long, up to 1-5 cm.

broad. Lip superior, with the spur 6-7 mm. long as long as

the petals, up to 1-8 cm. broad, inconspicuously 5-7 keeled

near the base, with 3 rows of lacerated papillae extending to

about the middle of the intermediate lobe, side-lobes small,

obtuse, intermediate 1-4 cm. long and broad. Column 6 mm.

long, produced at base into a distinct foot; anther sub-

orbicular, very shortly rostrate at base ; gland of oval pollinia

transversely elliptical. L. Bolus. (M. A. Holland, 18.

Disa Galipinii, Bolfe in Dyer, Flor. Cap. vol. v. sect. 2, 230.

Disa Galpinii is one of the lesser known species of this large

genus, and has not been figured before. Only one collection

is recorded in the Flora Capensis, namely, E. E. Galpin, 6838,

from Midlothian Farm in the Maclear District, Griqualand

East, at an altitude of 5600 feet. This was made in March

1904. In April 1914 the species was found again by Mr. A. G.

McLoughlin on the mountains near Engcobo, and we are

indebted to him for the specimen figured here.

The ascending or erect spur is rarely found in the genus and

not in any other species with such small flowers as those of D.

Galpinii. The foliage is well developed both as to the number

of leaves and their size; so that in order to conform to the

exigencies of space the lower portion of the plant (Figs. 1, 2)

has been reduced to about half the life-size. The second fully

produced leaf, however, is given in its natural size showing the

sheathing basal portion.

Description : — Plant glabrous, 62 cm. high. Tuber sub-

cylindrical, 9 cm. long, 2 cm. diam. Stem densely leafy

throughout, the 2 basal sheaths 6-12 cm. long. Leaves 10-11,

the lowest 25 cm. long, up to 2*5 cm. broad, linear, tapering

upwards, acute or acuminate, long-sheathing, the uppermost

4 cm. long with a very short sheath. Raceme rather dense,

16 cm. long. Bracts erect, 2-5-0-7 cm. long, exceeding the

ovary. Lateral sepals spreading or recurved, oblong-ovate,

6 mm. long. Odd sepal galeate, the mouth suborbicular or

oval ; spur erect, straight or curved forwards, the apex usually

obliquely inflated, 1*8 cm. long. Petals erect-incurved,

obliquely ovate, 4-5 mm. long. Lip linear up to 6 mm. long,

up to 2 mm. broad. Anther ascending, the lobes diverging,

connective short ; middle lobe of the rostellum minute.

Stigma large, suborbicular. L. Bolus. (A. G. McLoughlin.)

vol. iii. p. 535.

Eulophia barbata, Spreng. Syst. iii. 720.

For the student who is trying to identify living orchids

with those which have been described from dried material only,

the Eulophiae of the Port Elizabeth, Albany, and Bathurst

Divisions have a special interest. For, as this area was fairly

well explored by the early collectors, it can be reasonably

assumed that some of the more widely spread species of the

Eastern Region would have been collected here first, and would

therefore represent the typical forms described. Reasoning

thus we are led to conclude that in Drege’s collection from

“ between Van Stadens Berg and Bethelsdorp ” we have the

type of Eulophia barbata. The specimens figured here are

from the type-locality, that of Mr. F. R. Long being from

Parson’s Vlei, near Port Elizabeth, in open veld; but we have

some doubt regarding our identification because we have not

seen Drege’s plant. Moreover, there appear to be two species

included in the citations given in the Flora Capensis, where

Scully, 173 and MacOwan , 184 are quoted both under E. barbata

and E. MacOwani. These two species are evidently closely

allied and difficult to distinguish in the dried state. In living

plants, however, differences are manifest in the smaller size of

the flowers, as well as of the whole plant, the white petals, and

the inferior position of the lip, as well as the larger side-lobes

of the latter. Another and an even closer ally of E. barbata is

E. ovatipetala, Rolfe, from the same area. It was described

from incomplete material and is, therefore, awaiting further

investigation.

Miss Page’s drawing was made from a plant which flowered

in the National Botanic Gardens in February 1918, sent by

Mrs. T. V. Paterson of Redhouse, and the additional figures

were made from Mr. Long’s collection of March 1932.

It should be noted that the plant figured as E. barbata in

the leones Orchidearum, iii. t. 12, is probably E. purpurascens,

Disperis disaeformis, Schlechter in Verb. Bot. Ver. Brandenb. xxxv.

(1893), 47.

In this genus are to be found some of the daintiest-

looking of the South African flowers, whose beauty is usually

associated with glowing colours, large size, and other sturdy

qualities that strongly contrast with the almost ethereal

appearance of such species as D. Fanniniae, D. Wealii, and

D. disaeformis, the subject illustrated here. It is impossible

to reproduce the delicate charm of this plant with its pale and

almost transparent flowers, flushed with mauve and green, and

the purple-backed dark green leaves, making a delightful

harmony in shades of purple and green. The species seems to

have escaped the notice of the older collectors, and was first

recognised as being new by Schlechter, whose very becoming

name of disaeformis was published in 1893. It has been

recorded from the Riversdale, Knysna, and Albany Divisions

in the Flora Capensis ; and since then the late Miss Pegler

(No. 1784) found it at Kentani, flowering in July, and lastly,

Dr. G. Rattray got it near East London, flowering in August

1917, from whose specimens the drawing was made. In the

other areas the flowering-period given is October and

November. The type was collected on the slopes of the

Langebergen near Riversdale.

Description : — Plant 17 cm. high, basal sheaths 1-2, up

to 2 cm. long. Leaves 2, distant, internode 2 cm. long,

amplexicaul, the blade ovate, acute or acuminate, glabrous,

2-5-3 cm. long. Bracts spreading, leafy, ovate, acuminate,

0*7-1 -5 cm. long. Pedicels very short. Sepals spreading

forwards and soon defiexed, obliquely ovate, acuminate, the

short obtuse sac placed near the middle, all 7 mm. long ; odd

sepal galeate, erect, the obtuse spur pendent, 2-3 mm. long.

Petals very shortly clawed, the lip suborbicular or obliquely

orbicular-ovate, up to 7 mm. long. Lip projecting backwards

into the spin1 of the galea, the lamina somewhat hastate-

auriculate, the appendage inflexed, furnished with piliform

papillae. Rostellum suborbicular, the margins defiexed ;

gland-bearing arms erect, with a half-twist. L. Bolus.

18.

Two collections are included in the above description,

namely, that of Miss S. M. Stent from “ The Willows,” Pre-

toria, January 1914, and that of the Rev. F. A. Rogers from

the Premier Mine, December 1917. Our Plate represents the

latter.

This species has the same general aspect as its ally, Eulophia

fragrans, Schltr., figured under Plate 319 of this work. Both

species are similarly coloured, and both occur near Pretoria,

the latter flowering, as far as our records go, in October and

November and the former in December and January. The

differences lie in the leaves being longer and narrower in

E. pretoriensis and fully developed contemporaneously with the

flowers ; the sheaths on the scape and the bracts are also longer

and narrower ; the flowers are larger with the sepals narrower

and the petals rather more than twice as broad as the sepals,

and the column less than half as long as the lip. Finally, the

foot of the column is not produced to the same extent as it is

in E. fragrans.

There is another species, E. Nelsoni, Rolfe, from “ Wander-

wald,” in Pretoria District, which appears from the description

to be even a closer ally of E. pretoriensis. It seems to be little

known, for only one collection has been recorded, and the

description was made from dried material. When more

information is available, our species may prove to be nothing

more than a form of E. Nelsoni with longer and broader leaves,

larger flowers, and with the papillae on the lip inconspicuous.

Description : — Plant 30-40 cm. high. Leaves 5-6, fully

developed during the flowering-period, ascending or spreading,

acute, 8-52 cm. long, 1-1-8 cm. broad, the primary veins

rather prominent. Scape up to 6 mm. diam. ; sheaths 6,

linear-lanceolate, acuminate, up to 9 cm. long. Raceme 10-13

cm. long, 11-13-fl., flowers ascending or spreading. Bracts

acuminate, 3-1 cm. long. Pedicels in fruit up to 8 mm. long.

Sepals spreading, linear-lanceolate, long-acuminate, up to

3-6 cm. long, 7 mm. broad at the base. Petals ovate-oblong,

acute, up to 3-3 cm. long, 1-5 cm. broad. Lip superior, with

the spur 2 mm. long up to 2-3 cm. long, 2-5-keeled near the

base, the lacerated papillae in 3-5 rows, inconspicuous,

extending a little beyond the middle of the intermediate lobe,

side-lobes rounded, 3 mm. broad, intermediate 1-4 cm. long,

1-3 cm. broad. Column about 7 mm. long, produced at base

into a short foot. L. Bolus. (Miss Stent, Government

ARCTOTIS acaulis.

Cape Province.

Compositae. Tribe Arctotideae.

Arctotis, Linn. ; Benth. et Hook.f. Gen. Plant, vol. ii. p. 458.

Arctotis acaulis, Linn. Sp. PI. ed. 2, p. 1306 ; FI. Cap. vol. iii. p. 450.

This handsome species of Arctotis flowered at the Division

of Plant Industry, Pretoria, in 1927. It is closely related to

A. Fosteri N.E. Br. which we illustrated on Plate 3, but differs

not only in the colour of the ray-florets but also in the structure

of the disc-florets. A casual examination of specimens named

Arctotis acaulis suggests that probably more than one species

is involved. Linnaeus in the third edition of the Species

Plantarum , p. 1306, quotes t. 35 of Commelin’s Plantarum

rariorum, etc. as A. acaulis. If we accept this figure as

illustrating Linnaeus’ species, then we do not think our plant

can be A. acaulis L. Our plant matches the figure in Jacquin’s

Plantarum rariorium Horti Caesar ei Schoenbrunnensis (t. 161),

which he names A. speciosa, but it does not agree with the

plate in the Botanical Magazine (t. 2182), which is cited as A.

acaulis. The differences in colour and size of the flower-head

appear to be too great to consider these as mere forms of a

single species. Without reference to types we are unable to

undertake this critical examination and for the time being

regard our plant as Arctotis acaulis in the sense of the Flora

Capensis.

We are uncertain from where our plant originally came.

Description : — A sub-acaulescent plant. Leaves 5-10 cm.

long, -8-12 cm. broad, lanceolate in general outline above,

with the blade irregularly pinnatilobed, attenuated at the base

into a long petiole, obtuse, scabrous above, densely white-

woolly beneath. Scape up to 15 cm. long, bearing a few

leaves, woolly, with intermingled setae which are banded with

red. Flower-head 8-5 cm. in diameter when fully expanded.

Involucral-bracts in several rows; the outer acuminate and

woolly ; the inner ending in an obtuse membranous appendage.

Receptacle convex. Disc floret : Corolla-tube 4 mm. long,

1*5 mm. diam. above gradually narrowing downwards; lobes

1 mm. long, oblong, with a thickening at the back below the

apex. Anthers obtuse at the base, with an ovate apical

appendage. Style 5 mm. long, thickened and cylindric above,

shortly 2-lobed, discoid at the base. Ovary with a basal tuft

of long hairs and with 2 collateral cavities. Pappus scales

4 mm. long, obovate. Ray floret : Corolla-tube 4-5 mm. long,

1-5 mm. diam., almost oblong in outline, with three small

spathulate lobes in the throat; limb bright yellow above,

reddish beneath, 2-5 cm. long, 5-5 mm. broad. Style 4 mm.

long, thickened above ; lobes oblong-linear, obtuse. Pappus

as in disc-floret. (National Herbarium, Pretoria, No. 14,853.)

Homeria lilacina, L. Bolus in Ann. Bolus Herb. vol. iii. p. 9.

On two previous occasions (see Plates 306, 417) we figured

and described species of Homeria and recently had the oppor-

tunity of figuring a third species, also described by Mrs. F.

Bolus who has devoted considerable attention to our South

African petaloid monocotyledons. Homeria lilacina in general

appearance resembles some species of Moraea more than it

does many species of Homeria, and at first sight might quite

easily be mistaken for the former genus. The style-branches,

with the papillae on their upper margins, however, indicate

that our plant properly belongs to the genus Homeria. The

species was first collected near Matjesfontein in the Cape

Province and was subsequently found in the neighbourhood of

Worcester. Corms from this locality were planted at the

Division of Veterinary Research, Onderstepoort, near Pretoria,

and flowered in October 1932. It was from these plants that

our Plate was prepared. Several species of Homeria are known

to be extremely poisonous to stock, and it is probable that H.

lilacina may also prove to be a poisonous species though it

has not been tested yet.

Description : — Corm 2-3 cm. in diam., covered with pale-

brown tunics. Scape up to 30 cm. high. Leaves 3, one radical,

two cauline; lowest up to *6 m. long; all 3-6 mm. broad,

distinctly ribbed, glabrous. Flowers arranged in cymes.

Outer spathe-valves sub-membranous, 2-5-4 cm. long, acumin-

ate. Perianth-segments 1-2-2 cm. long, 4 mm. broad, oblan-

ceolate, sharply spreading in the upper half, lilac with a yellow

blotch at the bend. Staminal column 5 mm. long; anthers

3 mm. long, overtopping the style-branches; style-branches

2-5 mm. long, shortly bifid at the apex. (National Herbarium,

We previously figured a species of Asparagus (see Plate

409) and take this opportunity of illustrating a second species

of this interesting genus. The specimen illustrated is from a

plant growing at the Division of Plant Industry, Pretoria, and

is among the most graceful species in the genus. It differs

from A. suaveolens in the more slender habit and the less

prominent spines in the fascicles of the phyllodes. The late

Prof. C. E. Moss devoted much time to the nomenclature of

the South African species of Asparagus, and we are indebted to

him for naming our plant.

Description. — A lax scrambler. Branches slender, very

minutely puberulous, with the internodes usually longer than

the phyllodes. Phyllodes up to 7 mm. long, acicular, arising

in the axil of a reduced leaf which is produced into a minute

downward pointing spine. Flowers one or two (very rarely

three) from each group of phyllodes. Pedicels 5 mm. long,

jointed below the middle. Perianth-segments 3 mm. long,

1 mm. broad, oblong, obtuse, membraneous with a median

keel. Filaments f as long as the per'anth-segments, mem-

branous, broadly linear; anthers -75 mm. long, oblong in

outline. Ovary 1-25 mm. long, globose, 3-lobed; style 1 mm.

long, divided about half-way down; lobes slightly reflexed,

papillose at the apex; ovules 4 in each ovary-chamber.

Caralluma, R. Br. ; Benth. el Hook. f. Gen. Plant, vol. ii. p. 782.

Caralluma tessellata, Pillans in Kew Bull. 1933, p. 187.

This remarkable plant was discovered by Mr. P. Ross

Frames in October 1929 near the main road between Nieu-

werust and the Zout Rivier, in the Van Rhynsdorp district.

In February 1931 it flowered in Mr. Frames’ garden near

Cape Town and from these plants the accompanying Plate was

prepared. As far as we know the stems are unique in the

genus Caralluma, as it exists in South Africa. They exactly

resemble the stems of species of Echidnopsis found in North

Africa. The corolla and corona are those of a typical

Caralluma, and in general habit our plant resembles C.

Maughani Dyer, which was found in the same locality. The

coronas of the two species are, however, very different.

Description : — Stems erect from a decumbent base,

occasionally procumbent, up to 1 dm. high, 1—1 -3 cm. wide,

usually somewhat curved, sparingly branched at base, sub-

cylindric, longitudinally furrowed, very obtusely 6-angled,

the angles divided by transverse furrows into tetragonal or

hexagonal slightly prominent areoles, each with a minute

papilla-like rudimentary leaf, glabrous, bright green, indis-

tinctly marked with grey specks. Flowers in fascicles of 2-5,

in the longitudinal furrows near the apex of the stems, develop-

ing successively or several simultaneously. Pedicels ascending,

4-5 mm. long, glabrous. Sepals 2 mm. long, ovate-lanceolate,

acute glabrous. Corolla 8-9 mm. in diam., glabrous on the

lower surface ; lobes 3-4 mm. long, slightly reflexed, recurved

at the tips, ovate, acute, the upper surface convex, purple,

covered, except at the tips and margins, with papillae, each

tipped with a short, simple hair. Disk about 1 mm. wide,

convex, covered with short papilla-like hairs, pale green,

mottled with purple. Tube about 1 mm. deep, 2 mm. wide at

the mouth, smooth within, with a few papilla-like hairs at

the mouth. Outer corona about 1 mm. high, 2 mm. wide,

cupular, egg-yellow, lobes erect-spreading, transversely oblong,

separated by rounded sinuses, deeply emarginate, the teeth

obtuse or rarely acute. Inner corona lobes about 1 mm. long,

linear-oblong, obtuse, egg-yellow, incumbent on the backs of

the anthers, slightly recurved at the tips. — N. S. Pillans.

Cape Peninsula : Cirkels Vlei, Salter, 1861. ( Bolus Herbarium.)

Lachenalia Salteri, named after Captain T. M. Salter, who

found it near Cirkels Vlei, west of Smitswinkel Bay, between

Simonstown and Cape Point, in bloom in December 1931, is an

interesting addition to the list of Peninsula plants as well as

being of particular interest as one of the late-flowering forms of

Lachenalia, being with L. Muirii the last of the summer species.

Its unusually late-flowering period during the dry season may

be explained by the fact that it grows in damp black peaty

soil, which contains sufficient moisture for its needs.

Lachenalia Roodeae, though a much more robust species,

seems to be the nearest ally of our plant with its subspicate

inflorescence and exserted stamens, but the colouring of its

perianth is much more striking, and the outer perianth-seg-

ments are more tubular than those of Lachenalia Salteri, which

are slightly spreading, as in L. orthopetala. Also the leaves are

distinct, being conduplicate and falcate and sometimes even

circinate.

Description : — Plant glabrous, 15-21 cm. high. Bulb

globose, 1-7 cm. diam. Leaves 2, lanceolate-falcate, 7-12 cm.

long, 1-1*6 cm. broad; blade bright green, conduplicate ;

clasping base 1-5 cm. long, white. Inflorescence subspicate,

6-11 cm. long, 2-2*5 cm. diam. Bracts amplexicaul, lanceolate,

3-5 mm. long. Pedicles patent, 2-4 mm. long. Flowers

spreading or erect, subspicate, 11-12 mm. long, reddish-

purple; tube white, 2 mm. long. Outer segments oblong,

7 mm. long, 3 mm. diam., with a purple gibbosity at the apex;

inner segments oblong-obovate, emarginate, 2-3 mm. longer

than the outer, 4 mm. broad. Stamens slightly declinate,

exserted, filaments white. Ovary 2*5 mm. long ; style white,

finally exserted beyond the stamens. — W. F. Barker.

Clanwilliam Drv., Modderfontein ; Gillett, 3650. ( Bolus Herbarium.)

Lachenalia Gillettii, though not one of the most conspicuous

species of the genus, on account of its dainty colouring makes a

charming garden subject. It is named after Mr. J.- B. Gillett,

who found it growing in sandy soil at Modderfontein in the

Olifants River Valley, where it bloomed in August and Septem-

ber of 1930.

It is among the Lachenaliae with small tubular, sessile or

nearly sessile, flowers, having a marked difference in the length

of the perianth-whorls, and in these respects most nearly

approaches L. orchioides, and L. undulata, but differs from them

in having definitely exserted stamens, a character usually

confined to those species with more or less equal perianth-

segments and racemose inflorescences. Its bright green leaves

with fine impressed veins on the upper side also serve as a

distinguishing character.

Description : — Plant glabrous, 12-22 cm. high. Bulb,

1-1*5 cm. diam. Leaves 2, erect or spreading, obtuse, bright

green with impressed nerves on the upper side, glabrous,

6-14 cm. long, 2-2-5 cm. broad. Spike 4-10 cm. long, 2-5 cm.

diam. Bracts minute. Pedicels patent, 1-5 mm. long.

Flowers spreading or erect, subspicate, 9 mm. long, 4 mm.

diam. at the base. Outer segments oblong, acute, 6 mm. long,

2-5 mm. broad, white, pale mauve at the base, with a pale

green gibbosity near the apex, the extreme tip membranous

and recurved and tinged with purple ; tube 2 mm. long ; inner

segments oblong-obovate, longer than the outer by 2 mm., the

two upper 4 mm. wide at the apex, their apices spreading, the

lower longer and narrower, diverging from the rest, all the inner

segments white, apex acute, bright purple. Stamens declinate,

exserted ; filaments white, anthers dark. Ovary 2-5 mm. long,

green; style white, declinate, finally exserted beyond the

stamens. — W. F. Barker.

Whitehill in the Laingsberg Division and the Bonteberg in the

Ceres Division. Both collections were made by Professor

Compton.

It is one of the four species with hispid leaves, and the only

one of this group from the Karroo. It is quite distinct from its

allies in having two leaves and widely spreading segments, in

the latter character most nearly approaching L. latifolia ; but

it is unique in having the otherwise inconspicuous pale flower

made attractive by the bright purple, exserted filaments.

Description : — Bulb globose, 2 cm. long, 1-7 cm. diam.

Leaves 1-2, erect or slightly spreading, linear, acute, dark

greenish-purple, upper surface glabrous or covered with firm

spreading hairs, 2 mm. long, 8’5 cm. long, 1*4 cm. broad, the

base clasping the peduncle for about 2-5 cm. Peduncle dark

purple, 7 cm. long. Inflorescence racemose, 7-5 cm. long,

2*2 cm. diam., 12-50-flowered. Bracts small, ovate. Pedicels

about 1 mm. long. Flowers spreading ; perianth campanulate,

white, 6 mm. long ; tube short ; outer segments a little shorter

than the inner, 2’5 mm. broad; inner oblong, obtuse, 1 mm.

broad; all the segments spreading, white with a pale green

keel. Stamens much exserted, 7 mm. long ; anthers small and

yellow; filaments bright purple. Ovary 3 mm. long, 2 mm.

broad ; style purple, as long as the stamens. — W. F. Barker.

This charming Lachenalia was sent to the Bolus Herbarium

by Mr. H. Buhr from N ieuwou dt ville, where he found it in

flower in October 1930. The flowers are not large, but the

bright blue of the outer segments makes them conspicuous,

and when grown in masses they make beautiful patches of

colour. It is most nearly related to L. orchioides, but quite

distinct from it in having a more rigid peduncle, the flowers

more tubular, the outer segments only a little shorter than the

inner, and the tube narrower at the base. The inner segments

too are almost equal and only slightly spreading, giving the

flower a less bilabiate appearance than is usual in the tubular

forms, while the leaf is quite distinctive with its thickened

brown margin.

Lachenalia splendida, Diels, another blue Lachenalia, from

Windhoek in the Van Rhynsdorp Division, is known to me

only from the description ; but it seems quite distinct with its

outer segments only half the length of the inner, its reddish

stamens, and crisped leaf margin.

Description : — Plant, 18-24 cm. high. Bulb depressed-

globose, 2-2*5 cm. diam. Leaves 1-2, lanceolate, falcate, cuspid-

ate, 16 cm. long, 1*5 cm. broad; blade bright green smooth or

pustulate on the face and with a thickened brown margin;

clasping base white, tinged with mauve, 4-6 cm. long. Bracts

lanceolate, 2 mm. long. Inflorescence spicate, 2 cm. diam.,

6-9 cm. long. Flowers strongly sweet-scented, sessile, tubular,

erect, 1 cm. long, 3 mm. diam. at base. Outer segments oblong,

acute, 7 mm. long, 3 mm. broad, bright blue at the base shading

to rose with a brown gibbosity at the apex ; inner white oblong-

obovate undulate, emarginate and a little recurved with a pale

pink spot below the apex and a bright blue triangle at the base

larger than the outer by 3 mm. Stamens included, slightly

decimate ; filaments white. Ovary dark green, 3 mm. long ;

style white, as long as the stamens. — W. F. Barker.

The two species figured here illustrate the main groups into

which Conophytum has been divided, namely, the familiar cone-

shaped group, and the bilobed group, of which C. bilobum is a

good example.

C. colorans, which belongs to the former, or clumpy, group,

and very probably comes from Little Namaqualand, was given

to the National Botanic Gardens, Kirstenbosch, in 1916 by

Mr. N. S. Pillans. In 1917 it flowered and was drawn by Miss

M. M. Page. The plant has since died, and no subsequent

collection has been recorded. Superficially it resembles the

affinities of C. calculus, from Namaqualand, and is closely

allied to C. Purpusii, from Prince Albert, but may be dis-

tinguished by the colourful bodies, convex above, often with

confluent dots; the brilliant sepals and petals, the latter

arranged in fewer series; by the less prominent disc; and

5 instead of 6 stigmas wThich are revolute only at the tips.

C. Edwardsiae, found by Miss Edwards at Warmbaths in

July 1915, flowered in May 1917. One of the most picturesque

of the genus, it is closely allied to C. Luckhoffii from Citrusdal,

and C. turrigerum from the Paardeberg. Together with four

others it forms a subsection of the present group Biloba, which

might well be called § Turrita. The bodies of this section are

bilobed, but their lobes, instead of being compressed and

keeled, take the form of small turrets or towers, and are

usually of a dull slate-grey or brownish shade when flowering,

and sunburnt red when approaching the resting stage. The

flowers, which open in the day, are showy, and range from

shining white to deep rose, in our present species a delicate

soft pink.

Description : — A. Conophytum color ans, Lavis. Growths

forming clumps of 15 to 20 corpuscula, sometimes with the

remains of old sheaths apparent. Corpusculum pear-shaped,

convex above, elliptic in outline, spotted, pale green, sides

purple, up to 15 mm. high, 14 mm. wide and 15 mm. diam.

Flowers opening at night, strongly scented ; peduncle enclosed

in two green sheathing bracts. Calyx almost entirely exserted,

papulose, bright red; lobes 5, subequal, acute, 2 mm. long.

Corolla 10-12 mm. in diam. ; the white tube enclosed in the

calyx, 5 mm. long. Petals few, in 2 or 3 series, stiffly spreading,

linear, acute, up to 6 mm. long. Stamens in 3 series, exserted,

arising from the upper half of the tube ; the white filaments

up to 3 mm. long ; anthers small, yellow. Disk green, dentate,

2-5 mm. in diam. Ovary conical above. Style almost none.

Stigmas 5, filiform, revolute at tip, 3 mm. long.

A. Conophytum ornatum, Lavis in Notes Mesembm. II. 265.

B. Conophytum Vanzylii, Lavis in Notes Mesembm. II. 267.

These two species belong to a group of the glabrous cone-

shaped Conophyta which, with age, have more or less elongated

branches.

In C. ornatum the branches are well evident above ground,

whereas in C. Vanzylii, in which the intemodes are shorter,

they are much less evident, partly because they are more

decumbent.

C. ornatum was found at Umdaus, near Steinkopf, in Little

Namaqualand by Mr. H. Herre, Curator of the Stellenbosch

University Gardens. It flowered freely from March to May

1931 ; and as a subject for cultivation is gay and hardy. Its

flowers open in the day in full sunshine. Its petals are the

brightest of yellows, and exserted from the corolla-tube are

the deep claret stigmas, which add greatly to the general effect.

C. Vanzylii was first collected by Mr. G. van Zyl at Pof

Adder in the Kenhardt Division in May 1929, when our

figure B. a. was made. In 1930 he collected it again, and the

plant, figured as B. &., flowered in the National Botanic

Gardens in April 1931. The flowers open at first only in the

evening, then, as they get older, in the daytime. The bodies

are of a pale whitish-green without any markings.

Both these species are closely allied to C. Victoris, Lavi;', in

which, however, the flower throughout expands only at night.

C. ornatum is also distinct in having an ovary which is flat

above in contrast to the conical ovaries of the other two

species.

Description : — A. C. ornatum, Lavis. Plant branching,

up to 5 cm. high; branches thick, woody, wrapped in pale

brown imbricating sheaths. Corpusculum elongated pear-

shaped, grey-green, inconspicuously spotted, viewed laterally a

little raised round the orifice, up to 2*3 cm. high, 1-2 cm. broad,

1-5 cm. in diam. Calyx entirely exserted, fleshy, greenish-

white, 4 to 5 mm. long, 3 mm. in diam. ; lobes 6, ovate-

acuminate, pale green, 3 to 3-5 mm. Flowers up to 2 cm. in

diam. Petals about 30, laxly arranged in 2 to 3 series,

emarginate, yellow, up to 1 cm. long, 1*5 mm. broad; tube

4 mm. in diam. at the apex. Stamens about 25, in 4 to 5

series, upper exserted, up to 7 mm. long; filaments deep

claret ; anthers small, yellow. Disk inconspicuous, yellowish.

Ovary flat above. Style and stigmas deep claret, up to 2*5 cm.

long; stigmas 5 to 6, 1-5 mm. long, overtopping the stamens.

Transvaal: Ventersdorp. Mrs. F. Cooke, National Botanic Gardens,

Kirstenbosch, No. ^°-.

Our plant, found by Mrs. E. Cooke at Ventersdorp in the

Transvaal, seems to be most nearly related to Nerine flexuosa

var. Sander soni, illustrated in this work on Plate 139, both

having a long slender angular peduncle, a centripetal umbel,

and unappendiculate stamens ; but the flowers of N. falcata

are more dainty in shape and more delicate in colouring.

Our species also differs in having leathery falcate leaves,

with scabrous margins and an obtuse apex. The falcate

leaves most closely resemble those of N. lucida (figured on

Plate 134), but they are always raised well above the ground

and not prostrate, as seems to be the rule in N. lucida.

Description : — Plant glabrous, 57 cm. high. Bulb globose,

5-7 cm. diam. Leaves 5-7, synanthous, falcate, erect or

patent, with a half spiral twist, dark green, margin scabrous,

26 cm. long, 3 cm. broad, apex obtuse. Peduncle angular,

43 cm. high, 1-3 cm. broad; spathe valves oblong, 4-8 cm.

long, 1-8 cm. broad, membranous. Inflorescence a centri-

petal umbel, 20-25 fid., 24 cm. diam. ; pedicels 9 cm. long,

2-3 mm. diam. Perianth zygomorphic, the lower segments

diverging widely from the stamens, 5-6 cm. diam. ; segments

white, patent, then recurved, linear acute, towards the apex

a little undulate and rose pink, 4-4 cm. long, 5 mm. broad.

Stamens declinate; filaments 3-2 cm. long, rose pink. Ovary

PELARGONIUM Tysonii.

Pelargonium, L’Herit. Geran. (1787-88) t. 7 ; Benth. et Hook.f. Gen.

Pelargonium Tysonii, Szyszyl. in Polyp. Rehmann, 1888, p. 8 ;

Knuth, in Engl. Pflanzenreich, Geraniaceae, IV. 129, vol. ii.

This species belongs to a section of the genus Pelargonium

that has not yet been illustrated in this work, namely, the

section Hoarea, which is characterized by the tuberous root,

dwarf habit, and 5 or 4 petals as compared with the 2 petals

found in the closely allied section Seymouria.

In Knuth’s monograph ( Pflanzenreich , IV. 129, vol. II),

published in 1912, some 48 species are enumerated; but

many of them seem very little known. Probably the chief

reasons for this are that the plants die down after flowering,

and the leaves, usually polymorphic, are produced after the

flowering period. Nevertheless, several species have been

carefully studied in Europe and have been described and

figured in the magnificent works of Andrews, Sweet and

Jacquin. The first species recorded appears to be Pelargonium

longifolium, Burm. f., described and figured in Specimen

Botanicum de Geraniis, published in 1759.

The section Hoarea is concentrated chiefly in the south-

western region, about 12 species in all, occurring outside this

area, in the Karroo and Namaqualand, and 3 others extending

as far east as Uitenhage.

Our specimen agrees with the type of Pelargonium Tysonii ,

Szyszyl ( Tyson 328), collected at Murraysburg in 1879 and

said to be the same as Geranium ciliatum, Cav. [Cavanille! s

Dissertationes IV, anno 1787, 234, t. 118, f. 2). The new

trivial name Tysonii , was considered necessary because

P. ciliatum, L. Herit. and P. ciliatum, Willd. (both since

merged by Knuth in P. longifolium, Burm. f.) already existed.

Four collections of this species are represented in the

Bolus Herbarium; Bolus, 1800, collected in December 1867,

“ hills in Sneeuwberg near Zuurpoort Hotel ” ; Gill 65,

Blaauwater, Sneeuwberg ; Tyson 328, Murraysburg ; and

finally the plants collected by Mr. C. Watermeyer at Leopard’s

Vlei, Richmond, C.P., grown and flowered in Mr. H. H.

Bolus’ garden. The leaves were produced in August 1931

and the flowers in November. The Plate was made from

these plants. ( Bolus Herbarium, No. 20,058.)

Description : — Boot cylindrical, attenuated towards the

base, 6-5 cm. long, 2-5 cm. diam., tunics coriaceous. Leaves

about 9 in the rosette, slightly ascending, ovate or oblong,

rarely almost entire, usually irregularly pinnati-partite or

bi-pinnately divided, segments acute, ciliate; blade 3-4 cm.

long, 1 -3-2*5 cm. broad; petiole 4-5-5 cm. long; stipules soon

withering, adnate to the petioles for £ of their length, free

portion 7 mm. long, narrow and acutely pointed. Peduncles

several, appearing successively, hirsute, 4-10 cm. long; bracts

6 mm. long, lanceolate acute, densely hairy. Umbels 5-10-

flowered; pedicels 4-5 cm. long, pubescent. Sepals broad-

lanceolate acute, ciliate, the posterior erect, the rest recurved,

9 mm. long, 3-5 mm. broad, the spur very inconspicuous,

as long as the pedicel. Petals 5, posterior 2 slightly con-

stricted towards the middle and dilated at the apex, apex

emarginate, 2-2-3 cm. long, 5-6 mm. broad, anterior

petals obovate, abruptly narrowed at the base, rounded at

the apex, 1-8 cm. long, 3 mm. broad. Stamens, 5 fertile,

2 longest filaments 7 mm. long, 2 intermediate 5 mm. long,

and 1 short filament 3 mm. long, 5 staminodes all equal,

nearly as long as the short stamen. Gynaecium silky, 6 mm.,

Pycnostachys is an African genus of about 40 species,

of which three occur in South Africa and are found in the

Transvaal, Eastern Orange Free State, Natal, and East

Griqualand. The three South African species have all been

recorded from the Transvaal Drakensberg and are evidently

outliers from tropical Africa. One of these South African

species also occurs in tropical Africa. P. purpurascens

occurs as far south as East Griqualand, which is the southern-

most limit of the genus so far as known.

Our specimens were collected by Mr. A. O. D. Mogg,

M.A., in Debbe’s Ravine, Garsfontein, near Pretoria. This

record is interesting, as we have received from the same locality

other plants which belong to the flora of the north-eastern

Transvaal and which are outliers from that flora. At the

time the specimens were collected they were past their prime

and our Plate does not do full justice to what is really a

beautiful plant and one well worth the attention of horticul-

turists.

Description : — A herbaceous shrub, up to 1 m. high.

Branches 4-angled, pubescent. Leaves sessile, 9 cm. long,

1 cm. broad, becoming smaller above, linear, obtuse, with

the margins irregularly toothed, pubescent. Inflorescence

of terminal and axillary spikes, often arranged in a paniculate

manner at the ends of the branches. Spikes 4-5 cm. long,

4*5 cm. in diam. (including the corollas). Calyx-tube 1-5

mm. long; lobes 5 mm. long, linear-subulate, pubescent.

Corolla 2-lipped, pubescent ; tube sharply deflexed at about

the middle, narrow and straight for 5 mm. below the deflexion,

then dilated for 5 mm. above the deflexion ; upper lip 1*5 mm.

long, 3 mm. broad, quadrate, 4-lobed ; lower lip 6 mm. long,

boat-shaped. Stamens included in the lower lip. Style

shortly exserted; stigma simple. (National Herbarium,

Africa by 40 to 50 species, this is only the second opportunity

we have had of figuring a member of the genus. On Plate 436

we included a species from the northern Transvaal. The

plant shown on the accompanying Plate comes from Natal,

but is also known to occur in the Uitenhage district. We are

indebted to Miss C. Letty, who collected the specimen at

Shelly Beach on the south coast of Natal. She describes

it as a shrubby bush up to 4 ft. high found growing on the

wall of a bridge over a culvert. The plant has large pale

yellow flowers with dark red centres, which open in succession

and close at sunset.

The genus Hibiscus contains about 300 species, found in

all warm countries. Those in South Africa are widely dis-

tributed and many of them have exceptionally beautiful

flowers and are worthy of cultivation.

Description : — A shrub about 1 m. high. Branches

finely and densely stellate-pubescent, with scattered sharp-

pointed tubercles. Lower leaves petioled ; petioles up to

11 cm. long, stellate-pubescent, with scattered sharp-pointed

prickles ; blades up to 9 cm. long and 10 cm. broad, palmately

lobed, stellate-pubescent ; lobes coarsely serrate ; upper leaves

undivided, oblanceolate, coarsely toothed. Flowers arranged

on the branches in a pseudo-raceme. Pedicel *5-1 cm. long,

densely villous with stellate hairs and with a few sharp-

pointed prickles. Epicalyx of 8-9 linear segments, pubescent.

Calyx-lobes about 2 cm. long, about 7 mm. broad, ovate-

lanceolate, very densely setose with stiff hairs from bulbous

bases. Corolla when expanded about 7 cm. in diam. ; lobes

obovate, oblique, pale yellow with a deep maroon base.

Style 4-5 cm. long; stigmas capitate, each surrounded by a

fringe of hairs. (National Herbarium, Pretoria, No. 13,046.)

Utricularia prehensilis, E. Mey. Comm. i. 282; FI. Cap. vol. iv.

sect. ii. p. 432.

On Plate 243 we showed an example of an insectivorous

plant, and on the accompanying Plate we figure another

belonging to this interesting group. The genus Utricularia

contains over 100 species, mainly massed in the tropics of

both hemispheres. They are rootless aquatic or terrestrial

herbs, more rarely epiphytes, and usually have minute

bladder-like organs in which small organisms are trapped

and partially absorbed. The species of Utricularia are

commonly known as “ bladder- worts.”

We are indebted to Miss C. Letty for the specimen figured,

and which she found near Shelly Beach on the south coast

of Natal. The plants were growing in mud and were either

decumbent or clinging to reeds, etc.

Description : — A slender plant up to 20 cm. long. Leaf

solitary, 1 cm. long, 1 mm. broad, linear, obtuse; modified

leaves matted with a few globose shortly-stalked bladders

about -5 mm. in diam. Peduncle up to 15 cm. long, filiform,

twining, flexuous, bearing 1-3 flowers. Bracts about 2 mm.

long, ovate, acute, the lower barren. Pedicels 7 mm. long.

Calyx-lobes membranous; upper 7 mm. long, 4 mm. broad,

ovate, acute, many-nerved; lower 5 mm. long, 3 mm. broad,

ovate, lanceolate. Corolla yellow, 1-7 cm. long, with the

habit of twisting as the flowers mature until the lower lobe

is uppermost ; upper lip 7 mm. long, 4-5 mm. broad, oblong-

spathulate, with rounded entire or slightly emarginate tip;

lower lip 1-3 cm. long, broadly ovate, shortly bilobed; palate

erect, almost parallel with the upper lip, 3-gibbous; spur

descending, slightly curved, tapering 8 mm. long. Filaments

2 mm. long; anthers about 1 mm. long. Ovary sub-globose,

gradually passing into the style. (National Herbarium,

Pretoria, No. 14,111.)

Raphionacme Galpinii, Schltr. in Engl. Bot. Jahrb. vol. 18, Beibl. 45. 14;

FI. Cap. vol. iv. sect. i. p. 536.

The genus Raphionacme is confined to Africa and is

represented by about 25 species. In South Africa nine are

recorded, mostly from the Transvaal. All species of the

genus have large tubers or clusters of fleshy fusiform roots

from which, usually, dwarf simple or branched stems arise,

though in two of the South African species the stems are

twining. Raphionacme Galpinii is the only species which

occurs in the neighbourhood of Pretoria, and it was only

recently that we had an opportunity of figuring it. Our

plant was collected in October 1931 by Mr. A. O. D. Mogg,

M.A., on the hills above Sunnyside, Pretoria, where it is

found occasionally.

Description : — Tuber 8 cm. in diam., 14 cm. long, with

a distinct neck 3 cm. long and 1*5 cm. in diam. Stem (includ-

ing the inflorescence) 7 cm. high. Leaves 2-4 cm. long,

lanceolate, narrowed into a short petiole, densely pilose.

Inflorescence a many-flowered cyme. Bracts 4-6 mm. long,

subulate, pubescent. Calyx-lobes 3 mm. long, linear,

tapering upwards, pilose. Corolla 1 cm. diam. when

expanded ; tube sub-campanulate, almost glabrous ; lobes

3-5 mm. long, 2 mm. broad, oblong-lanceolate, obtuse, pilose

without. Corona arising at the mouth of the corolla-tube;

lobes transverse-rectangular at the base, 3-fid, with the

middle lobe long-filiform and the side lobes shortly ovate.

Tinnea Galpini, Briq. in Bull. Herb. Boiss. 2nd series, iii. p. 1094 ; FI. Cap.

vol. v. sect. i. p. 383.

The genus Tinnea is represented in Africa by about 20

species, one of which extends into Arabia. Only one species,

Tinnea Galpini, is recorded from South Africa and was first

collected by Mr. E. E. Galpin in the neighbourhood of

Barberton in the north-eastern Transvaal. It differs from the

other South African members of the tribe Ajugoideae in

having an inflated, 2-lipped calyx when in fruit. Tinnea

Galpini is a small shrub with sweetly scented, violet flowers and

is restricted to the mountains in the Barberton district.

We are indebted to Mr. J. J. Nouhuys, B.Sc., for the

specimens, which he found on serpentine formation round the

Munich-Myburgh asbestos mine near Kaapsche Hoop.

Description : — A small shrub 15-40 cm. high, densely

and shortly pilose. Leaves shorter than the internodes,

1*2 cm. long, 7 mm. broad, elliptic, obtuse, usually shortly

and bluntly mucronate, entire, shortly ciliate, pubescent

beneath, glandular above. Flowers solitary in the axils

of the upper leaves forming a pseudo-raceme at the ends of

the branches. Pedicels up to 8 mm. long, 2-bracteolate,

densely pilose. Calyx purplish, 2-lipped, about 7 mm. long,

pilose; tube campanulate; lips about 2-5 mm. long, 7 mm.

broad, with the upper lip only slightly exceeding the lower lip.

Corolla claret or prune-coloured, about 9 mm. longer than the

calyx, 2-lipped, pubescent without ; tube funnel-shaped,

10-11 mm. long, annular-pilose within ; upper lip about 3 mm.

long, about 7-5 mm. broad, emarginate; lower lip up to

7 mm. long, about 10 mm. broad, 3-lobed, with the median

lobe transversely oblong and the lateral lobes broadly

rounded, 3 mm. long and 4 mm. broad. Stamens ascending

under the upper lip of the corolla, slightly exserted ; the lower

pair the longer; anthers 2-thecous. Ovary shortly 4-lobed;

style 4 mm. long, shortly 2-fid. (National Herbarium,

Pretoria, No. 8,826.)

Zotjtpansberg DiSTR. : — In sandy soil between Zoutpan and Waterpoort,

Obermeyer, Schweickerdt and Verdoorn 403, 405, 411. (Type from farm

Chapudi.)

This rather striking species of Caralluma occurs in sandy

areas at the foot of the northern slopes of the Zoutpansberg.

While the aerial parts appear to grow in isolated tufts, an

examination shows that they are connected by long, jointed

underground stems. Usually the clumps are found in open

fully exposed patches of deep sand somewhat impregnated

with lime, though occasionally they are found in the shade

of trees. Though the plants are scattered they are quite

plentiful.

Description : — Plant forming long rhizomes. Stems in

tufts of 7-12, simple or branched at the base, about 7 cm.

long, 4-angled, green with purple-brown markings ; teeth

up to 1-5 cm. long, deltoid, mucronate, with 2 minute teeth

just below the apex. Flowers usually 3, arising about midway

on the stems, developing in succession. Peduncle stout,

under 1 cm. long, glabrous. Pedicels about 5 cm. long, 2 mm.

in diam., green with small purple-brown spots at the apex,

glabrous. Buds oblong in outline, distinctly 5-angled.

Calyx-lobes about 1 cm. long, lanceolate. Corolla 5 cm. in

diam. when expanded, yellowish-green with small purple-

red spots ; disk flat ; lobes 2-2 cm. long, 7 mm. broad, oblong,

spreading-recurved, with reflexed margins, finely rugose on

face, shortly ciliate and with long white vibratile hairs on the

lower §. Corona dark-purple-red, appearing 1 -seriate; outer

corona shallowly basin-shaped, with recurved margins ; inner

corona fused with the outer at the base and then produced

into 5 oblong-spathulate lobes. (National Herbarium,

Pretoria, No. 15,271.)

CEROPEGIA SETLFERA.

Ceropegla, Linn. ; Benth. et Hook. f. Gen. Plant, vol. ii. p. 779.

Ceropegia setifera, Schltr. in Engl. Bot. Jahrb. vol. 20, Beibl. 51, 48 ,

FI. Cap. vol. iv. sect. ii. p. 821.

The species of Ceropegia figured on the accompanying

Plate is related to those shown on Plates 382 and 387. As

will be seen from earlier plates, e.g. 39, 44, 191, the corolla

lobes may be connate in quite a different manner. It is

the peculiar way in which the lobes of the corolla are con-

nected which gives the charm and fascination to the flowers

of the genus. Ceropegia, like the genus Raphionacme, has

a tuberous root-stock or a cluster of thick, fleshy roots and

more rarely with ordinary stout root-fibres. The species

we illustrate has thick fleshy roots. We are indebted to Dr.

H. G. Schweickerdt for the specimens, which he found growing

in the shade of Celtis Kraussiana on the banks of the Pienaar’s

River, Pretoria district, where it was fairly abundant.

Description : — A twining plant, climbing up small trees.

Stem about 1 mm. in diam., glabrous; internodes 4-5-8-5 cm.

long. Leaves varying from T6 to 6 cm. long, 1-4 cm. broad,

ovate-oblong to almost oblong, apiculate at the apex, rounded

or sub-cordate at the base, with the veining distinct above

and beneath, ciliate, sparsely pilose above and beneath.

Flowers solitary or 2-3 together in the axils of the leaves,

whitish with purple markings (the markings vary so that the

flower may be more purplish than white), greenish above.

Peduncle about 1*3 cm. long, glabrous. Calyx-lobes 2 mm. long,

lanceolate, acute, shortly setose. Corolla-tube curved, 2 cm.

long, 4 mm. in diam., inflated at the base, glabrous without,

hairy within; lobes 7 mm. long, folded into falcate plates,

connivent at the apex, glabrous without, with long reflexed

hairs within. Outer corona-lobes 1-5 mm. long, 1 mm. broad,

almost quadrate, with a middle triangular lobe and 2 lateral

lobes more or less recurved, ciliate with long white hairs;

inner corona-lobes 2-5 mm. long, linear, projecting above the

staminal-column and then recurved. (National Herbarium,

Pretoria, No. 15,270.)

STULTITIA Tapscottii.

Cape Province. Transvaal.

Asclepiadaoeae. Tribe Stapelieae.

Stultitia, Phillips, nom. nov.

Stultitia Tapscottii (Verdoorn), Phillips, comb. nov.

In the description accompanying Plate 445, we suggested

the generic name Stapeliopsis for a plant which Dr. N. E.

Brown described as Stapelia Cooperi. At the time we were

not aware that Mr. N. S. Pillans had published the same

generic name for another member of the Stapelieae and that

Prof. Choux had also used this name for a Madagascar plant

{Ann. Mus. Colon. Marseille, 1932, p. 9). Stapeliopsis Pillans

has therefore priority over Stapeliopsis Choux and Stapeliopsis

Phillips.

In the Kew Bulletin (1927, p. 357), Stapelia Tapscottii

was described by Miss I. C. Verdoorn. We recently had

an opportunity of examining living material of this species

and find that it should be placed, for the reasons mentioned

under Plate 445, in the same genus as the plant described

there. As the name Stapeliopsis Phillips is not valid we now

propose the name Stultitia Phillips for the two species. Dr.

N. E. Brown is of opinion that the two species we have

separated from Stapelia should remain in that genus, but

a re-examination of the specimens, both of which have a

corona different from that of other species of Stapelia, appears

to us sufficient justification for placing them in a distinct

genus.

The original description {Kew Bull. 1927, p. 357) of our

plant states that the flowers are white. The specimens we

have examined sometimes have flowers of a pallid colour.

The synonomy is as follows : — Stultitia Cooperi (N. E. Br.)

Phillips, comb. nov. [= Stapelia Cooperi N. E. Br. ; Stape-

liopsis Cooperi (N. E. Br.) Phillips], Stultitia Tapscottii

(Verdoorn) Phillips [=Stapelia Tapscottii Verdoorn.]

Our present plant differs from Stultitia Cooperi (see Plate

445) in the structure of the corona; the inner corona being

long subulate and subclavate at the apices. We are indebted

to Mr. Eugene Marais for the specimens, which he cultivated

in his garden in Pretoria. The original locality is unknown.

Description : — Plants up to 12 cm. high. Stems branched,

with long conical teeth up to 2 cm. long, glabrous; each

tooth bearing 2 minute lateral teeth. Flowers in groups of

3 or 4. Pedicel -5-1-2 cm. long, glabrous. Bud subglobose.

Flowers 5 cm. in diam., when fully expanded, reddish w-ith

raised white markings. Sepals 7 mm. long, lanceolate, acute.

Corolla-lobes 2 cm. long, 1-1 cm. broad at the base, ovate,

subacuminate, with a few scattered vibratile clavate hairs;

disk with a slightly raised annulus 1 cm. in diam. Outer

ccyrona basin-shaped ; lobes almost oblong, bifid ; inner

corona-lobes produced into long subulate processes, sub-

clavate at the apex, broadened at the base, with a small

dorsal hump at the base of the broadened portion. (National

Herbarium, Pretoria, No. 15,264.)
