FLOWERING PLANTS OF SOUTH AFRICA

PREFACE

The cultivation of South African plants in Europe dates back to early

times.

Indeed, it may safely be assumed that it was in vogue soon after the

Dutch settlement at the Cape, for Holland during the 16th and 17th

centuries held first place in European horticulture. Her cities even

vied with one another in the establishment of gardens of exotic plants,

many of which came from the Cape.

These treasures created such interest and attracted such attention that

Cape plants soon became the fashion and object of envy throughout

Europe. Collectors were specially despatched to these shores for the

purpose of hunting out and securing their botanical wealth.

Evidence also is not lacking that the cultivation of indigenous plants

was carried out at the Cape prior to 1700.

Be this as it may, little remains to-day in South Africa to do credit to

the past preservation and cultivation of our native flora.

In recent years, however, considerable interest has again sprung up in

this direction; in fact, it is rapidly becoming fashionable to have a

rockery of aloes, vijgies, and other succulents as one of the chief

adjuncts to the garden.

Apart from these--perhaps better-known plants--there are many beautiful

flowering herbs, shrubs and trees of the veld, which might with

advantage be grown in our gardens and around our homes.

It is with the object of bringing these gems of nature to the notice of

the public that this publication is offered.

A work of this kind is of necessity a costly undertaking, and its future

existence and ultimate success will depend largely on the support which

it receives at the hands of the public.

The publication of the present volume has only been made possible

through the interest and keenness of a South African lady, whose love

for her country and its natural beauties has been the means of procuring

the necessary funds for the initiation of the work.

It is proposed to issue this publication as an illustrated serial, much

on the same lines as the well-known Curtis’s _Botanical Magazine_, and

for imitating which no apology need be tendered.

Should the publication be the means of stimulating further interest in

the study and cultivation of our indigenous plants amongst the rising

generation, the desire and object of its promoters will be achieved.

Living plants suitable for illustration, plants of economic value, or

plants of general interest, will always be gladly received and welcomed

by the Editor.

As regards the illustrations the Editor has been most fortunate in being

able to place the work of that skilful artist, Miss K. A. Lansdell,

before the public, while the descriptions have been prepared by Dr. E.

Percy Phillips, Botanist in charge of the National Herbarium, to both of

whom it is a pleasure to express one’s special thanks for the trouble

and care which they have taken.

For the information of those of our readers who have not been fortunate

enough to visit our country or our inland capital, it may be added that

the illustration on our cover represents a glimpse of the magnificent

Union Buildings at Pretoria, under whose shadow this work is being

prepared, and on whose site the plants here figured are grown.

It has been the Editor’s privilege and good fortune to see a

comparatively bare kopje converted in the course of a few years into the

site of a grand and stately building surrounded with many of the

country’s most beautiful and interesting herbs and shrubs.

The illustration depicts such characteristic plants as the arborescent

_Aloe Marlothii_, Berg.; the handsome _Aloe Wickensii_, Pole Evans (in

the centre); _Aloe aculeata_, Pole Evans; the neat _Aloe Peglerae_,

Schönland; _Cotyledon orbiculata_, Linn.; _Encephalartos Altensteinii_,

Lehm; and some arborescent euphorbias.

Although most of the plants just mentioned are typical of the vegetation

of the Transvaal, an endeavour will be made in our magazine to depict in

each volume as far as possible an equal number of floral representatives

from all the Provinces.

As the authority for colour nomenclature, _Colour Standards and Colour

Nomenclature_, by R. Ridgway, Washington, 1912, has been adopted.

* * * * *

This well-known garden plant, commonly called the “Agapanthus” or “Blue

Lily,” was introduced into cultivation in England from the Cape as far

back as 1692, and was figured by Commelin of Amsterdam in 1697.

In South Africa the plant is characteristic of the vegetation found on

high mountain ranges. It usually occurs on well-drained slopes.

It is a herbaceous plant with a tuberous rootstock from which 6-10 broad

strap-shaped leaves arise. The lower stalk is about a metre high, and

bears an umbel of 20-50 handsome blue flowers.

DESCRIPTION:--_Rootstock_ short, tuberous, with fleshy cylindric roots.

_Leaves_ dark green, 6-10, basal, 20-60 cm. long, 2-4 cm. broad,

strap-shaped, obtuse, glabrous. _Peduncle_ O·25-1 metre high, terete,

glabrous. _Inflorescence_ a many-flowered umbel. _Spathe-valves_ 2·5 cm.

long, 2 cm. broad at the base, ovate, acuminate, withering in the mature

inflorescence. _Floral-bracts_ 2·7 cm. long, linear. _Pedicels_ about 6

cm. long, terete, jointed at the apex. _Flowers_ blue; perianth-tube 1·7

cm. long, 6 mm. in diameter; lobes 2-5 cm. long, 9 mm. broad,

oblanceolate, obtuse. _Stamens_ inserted at the throat of the

perianth-tube; filaments 2·5-3 cm. long, arcuate; anthers oblong.

_Fruit_ a triquetrous capsule.

* * * * *

This remarkable Aloe was collected by Messrs. Wickens and Pienaar in

M‘Phathlele’s Location in the Pietersburg District during January, 1914.

Specimens brought to the Botanical Laboratories, Pretoria, flowered

during July and August of the same year.

In M‘Phathlele’s Location the plant occurs in vast numbers in a very

gregarious manner on the open sandy plains. In fact, it is not uncommon

to find long, continuous belts of thickly crowded plants extending for

two or three hundred yards in length. The plant is typical of the Low

Veld and the river valleys which run from the Zoutpansberg into the

Limpopo basin.

At first the racemes are furnished with widely separated spherical to

globular flower-buds which develop with considerable slowness.

The unopened flowers are rich nopal red (R.C.S.), tinged with green at

the tips. When open, the flowers become a sulphur-yellow (R.C.S.).

Our illustration was made from a plant in the Aloe collection at the

Botanical Laboratories, Pretoria.

DESCRIPTION:--A succulent, stemless plant. _Leaves_ 16-23 in a dense

rosette, glaucous, erect-spreading, 45-50 cm. long, 8-9 cm. broad at the

base, lanceolate-ensiform, acuminate, acute and recurved at the apex,

unspotted, somewhat flat at the base and canaliculate above, with

cartilaginous wavy and toothed margins; teeth pale brown and at right

angles to the margins, 1·5-2 mm. long, and about 8-9 mm. apart, deltoid,

recurved. _Inflorescence_ a panicle, with 5-7 spreading horizontal to

oblique branches with a few small deltoid-acute empty bracts at the

base. _Peduncle_ 06-1 metre high, stout, glaucous, naked. _Racemes_

densely flowered, 22-40 cm. long. _Flowers_ secund, all pointing towards

the centre of the inflorescence and at the same time slightly deflexed;

young buds distinctly globular; in open flowers nopal-red (R.C.S.),

green at the tips; mature flowers sulphur-yellow (R.C.S.) and tinged

with red towards the base. _Floral-bracts_ reflexed, 5-6 mm. long,

ovate-cuspidate, scariose, pellucid. _Pedicels_ recurved, 3-4 mm. long.

_Perianth_ 25 mm. long, cylindrical-ventricose; outer segments free for

15-17 mm., obtuse and recurved at the apex, 3-5-veined; inner segments

obtuse, recurved, tipped with auburn (R.C.S.) at the apex, with 3 inner

veins. _Stamens_ exserted for 11 mm.; filaments slightly recurved, the

exposed portion chestnut-brown (R.C.S.) to black. _Anthers_ mars-orange

(R.C.S.). _Style_ pale sulphur-yellow (R.C.S.), stout, recurved.

_Capsule_ shortly stipitate, 23 mm. long, 13 mm. in diameter,

oblong-ovoid.

Cape Province: Clanwilliam Division, near Clanwilliam, _Foster_.

* * * * *

This handsome species of _Arctotis_ was raised in the Garden of the

Division of Botany, Pretoria, from seed received in 1916 from Mr. C.

Foster, of Clanwilliam, after whom I have much pleasure in naming it.

The large size of the flower head and the delicate colouring of the

rays make it worthy of a place in all South African Gardens. At Pretoria

it flowers freely and has set mature seed.

DESCRIPTION:--A herbaceous perennial 60-90 cm. high. _Leaves_ many,

lyrate; lower leaves 30-40 cm. long, 7-9 cm. broad, lanceolate in

outline, obtuse, produced at the base into a long petiole, sparsely

pubescent on the upper surface, white-woolly on the lower surface;

leaf-lobes about 4 cm. long, 1-5·2 cm. broad, oblong, obtuse, with

toothed margins; the terminal lobe much larger, otherwise similar;

petiole up to 16 cm. long, flat on the upper surface, convex beneath,

sparsely glandular-pilose; upper leaves sessile, lanceolate, acute,

sparsely pilose, with more or less entire margins. _Peduncles_ pale in

colour at the base, gradually becoming indian purple (R.C.S.) towards

the apex, 17-19 cm. long, terete, striate, pilose, the hairs becoming

reddish and denser towards the apex. _Capitulum_ solitary, 7-9 cm. in

diameter when fully expanded. _Involucral bracts_ many-seriate; the

Transvaal: on kopjes near Mooi Plaates farm, in the vicinity of

Pretoria, _Miss J. Stuart_.

* * * * *

The specimens from which our drawing was made were collected by Miss J.

Stuart of Pretoria, on the slopes of stony kopjes near the farm “Mooi

Plaates,” about 5 miles out of Pretoria. During the spring months the

plant is very conspicuous on the kopjes when it flowers freely, usually

after the grass has been burnt off, and from this it derives its common

name of “Fire Lily.”

DESCRIPTION:--_Bulb_ 4-6 cm. in diameter, ovoid; tunics brown,

membranous. _Leaves_ 2-3, contemporary with or appearing after the

flowers, 30-50 cm. long, 0·8-1·2 cm. broad, linear, acuminate, acute,

tapering to a terete petiole above the flattened base, glabrous.

_Peduncle_ vandyke red (R.C.S.), 18 cm. long, lengthening in the fruit,

10 mm. in diameter, terete, hollow, glabrous. _Spathe-valves_ 4·5-5 cm.

long, 8 mm. broad near the base, linear, acute, membranous, glabrous.

_Inflorescence_, a 4-10-flowered umbel. _Flowers_ pendulous, scarlet-red

to carmine (R.C.S.), faintly scented; pedicels 2-4 cm. long,

strawberry-pink (R.C.S.), jointed at the apex; perianth-tube 5-6 cm.

long, tubular, narrowed at the base, with an inflated portion about the

middle; lobes 1·3-1·5 cm. long, 7 mm. broad, ovate-ellipsoid, acute,

with a small tuft of white hairs on the inner surface just below the

apex. _Stamens_ inserted just below the throat, a little shorter than

the perianth-lobes; anthers chrome-yellow (R.C.S.), oblong. _Ovary_ 1

cm. long, 0·5 cm. in diameter, ovoid; style about the length of the

perianth-tube, included; stigmas recurved. _Seeds_ black, flattened.--E.

This plant, the “Barberton Daisy,” has attracted much attention in

recent years as an addition to the herbaceous garden.

It was first discovered in the Transvaal by the collector Rehmann about

1878, and later by the Hon. R. Jameson on the mountains round Barberton.

In 1889 it flowered at Kew Gardens and was illustrated in the

_Gardener’s Chronicle_ for that year. Shortly afterwards a coloured

plate and description appeared in the _Botanical Magazine_ (t. 7087).

The specific name was proposed by the late Dr. Bolus, who himself

collected the species at Barberton.

A mass of these plants in full bloom is very striking, the scarlet rays

standing out in strong contrast to the green leaves.

The specimen from which the present illustration was made flowered at

the Botanical Laboratories, Pretoria.

DESCRIPTION:--_Rootstock_ perennial. _Leaves_ basal, numerous, 22-45 cm.

long, 5-10 cm. broad, somewhat oblong in general outline, deeply lobed,

with the terminal lobe broadly ovate, acute, pubescent on both surfaces,

especially on the veins beneath; petiole 25-40 cm. long, terete, pilose,

tinged with red at the base. _Peduncle_ 25-40 cm. long, terete, pilose,

bearing a solitary capitulum. _Capitulum_ 8-10 cm. in diameter when

fully expanded. _Involucral-bracts_ about 3-seriate, 1-1·5 cm. long,

lanceolate, acuminate, acute, woolly. _Receptacle_ flat, naked.

_Ray-florets_ female, scarlet to spectrum-red (R.C.S.); lower limb

represented by 2 linear strongly reflexed lobes. _Ovary_

glandular-pubescent. _Disc-florets_ hermaphrodite. _Corolla_ bilabiate;

tube 7 mm. long, cylindrical, glabrous; anterior limb of 2 linear

recurved lobes; posterior limb 3-toothed, spreading. _Ovary_ 6 mm. long,

cylindrical, glandular-pubescent; _stigma_ bifid.

* * * * *

This striking species of _Gladiolus_ belongs to the section

_Dracocephali_ of the genus which contains some seven species all

characterised by having the upper segments hooded. It is a favourite

with cultivators, and has also been taken up by nurserymen who grow

blooms for sale. Like a great many of our beautiful native species, it

was left to Kew Gardens to bring the species to public notice.

Corms of this _Gladiolus_ were brought to England by Mr. Thomas Cooper,

who collected in South Africa for Mr. Wilson Saunders. It first flowered

at Kew in 1872, when it was described and figured.

The species is easy of cultivation, and flowers at Pretoria in November.

Apart from the interest it is to gardeners generally, it should be of

special interest to breeders, as there seems little doubt that some very

fine hybrids could be raised from this species.

DESCRIPTION:--A tall plant O·9-1·2 metres high. _Corm_ red, 2·5-6 cm. in

diameter, globose; tunics chartaceous, broad, ultimately breaking up

into fibres. _Leaves_ 6-8, 60-90 cm. long, 2-3 cm. broad, ensiform,

acute, slightly narrowed at the base, glabrous, rigid. _Inflorescence_ a

lax 5-10-flowered spike, 20 cm. or more long. _Spathe-valves_ 5-9 cm.

long, oblong-lanceolate, sub-acute, kildare-green (R.C.S.). _Flowers_

large, hooded, lemon-yellow (R.C.S.), striped with scarlet-red (R.C.S.).

_Perianth-tube_ curved, 5-6 cm. long, trumpet-shaped, glabrous; three

upper lobes forming a hood 2-2·5 cm. broad, ovate or obovate, acute,

with a distinct claw; the posterior lobe crimson without, lighter in

colour within, smaller than the other two upper lobes; the three lower

lobes smaller than the upper lobes and strongly reflexed; the anterior

lobe 3-4 cm. long, O·5-2 cm. broad, broadly-lanceolate, acute,

lemon-yellow (R.C.S.) in the lower half; the lateral lower lobes 2-2·5

cm. long, 0·4-0·5 cm. broad, lanceolate, acute. _Stamens_ inserted at

the base of the perianth-tube, shorter than the upper lobes, arcuate.

_Ovary_ ellipsoid; style slightly longer than the stamens, arcuate;

stigmas terete, pubescent on the stigmatic surface. _Capsule_ 2-2·5 cm.

long, ellipsoid. _Seeds_ discoid.

* * * * *

The remarkable group of South African plants--the _Proteaceae_--still

continues to yield interesting novelties, though it was monographed as

recently as 1910. This is especially true of the genus _Leucadendron_,

on which much work remains to be done.

The specimens from which our illustration was made were collected by Mr.

T. P. Stokoe in the Klein River Mountains at Sinkerhausgat, near

Standford, in the Caledon Division. Mr. Stokoe has made some interesting

discoveries in this region, amongst which was this new _Leucadendron_

which he forwarded to the Division of Botany in September, 1918. It is

quite distinct from any other species of _Leucadendron_, inasmuch as the

male inflorescence is surrounded by large bracts giving it the

appearance of a _Protea_.

DESCRIPTION:--_Branches_ and branchlets glabrous. _Leaves_ 7-8·5 cm.

long, 1-2·1 cm. broad, oblong or oblong-lanceolate, obtuse, bluntly

mucronate, slightly narrowed at the base, glabrous, very finely

glandular when seen under a lens; leaves surrounding the inflorescence

longer. _Male inflorescence_ hidden by the upper leaves and quite

surrounded by brown bracts, shortly peduncled, 2 cm. long, 2·5 cm. in

diameter; the inner bracts 1·1 cm. long, oblong, obtuse, glabrous,

viscid, longer or as long as the inflorescence; the outer situated on

the short peduncle, viscid and reflexed; receptacle 7 mm. long, 8 mm.

broad, subglobose. _Floral bracts_ 1 mm. long, lanceolate, acuminate,

subacute, villous at the base. _Perianth_ 2 mm. long, glabrous. _Stigma_

clavate, much thicker than the style. _Female inflorescence_ hidden by

the upper leaves, very shortly stalked, 2·5 cm. long, 1·7 cm. broad, the

short peduncle bearing brown reflexed bracts; receptacle 1·6 cm. long, 3

mm. broad, cylindrical. _Floral bracts_ 6 mm. long, 1·1 cm. broad,

transversely oblong, villous above. _Fruiting head_ 3·5-4 cm. long, 3·5

cm. in diameter; scales 1·5 cm. long, 1·2 cm. broad, suborbicular,

slightly narrowed at the base, tomentose without, except near the apex.

_Fruits_ 7 mm. long, 6 mm. broad, obovate in outline, flat on one side,

convex on the other, honeycombed, with a narrow membranous wing.

This beautiful little _Tulbaghia_ has a special interest attached to it,

inasmuch as it flowered in Baron von Ludwig’s garden at the Cape of Good

Hope, and was there illustrated and described by Harvey, who sent his

description and drawing to the _Botanical Magazine_ for publication. In

this respect it differs from most of the other Cape plants, which were

described and figured from specimens grown in Europe.

The present illustration was made from specimens cultivated at the

Botanic Gardens, Durban, Natal, from tubers presented by Mrs. Todd of

Pietermaritzburg. Notwithstanding the unpleasant odour of garlic, the

species is worth cultivation. It is commonly known as the “Wild Garlic.”

DESCRIPTION:--_Rootstock_ tuberous. _Leaves_ crowded; basal leaves

rudimentary and membranous; upper leaves 6-10, erect, 20-30 cm. long,

5-8 mm. broad, linear, acute, glabrous, concave on the upper surface,

rounded beneath. _Peduncles_ erect, 30-60 cm. long, terete.

_Inflorescence_ a 10-20-flowered umbel. _Spathe-valves_ 2-2·5 cm. long,

5 mm. broad at the base, ovate-linear, acuminate, acute, membranous.

_Pedicles_ 2·5-4 cm. long, terete. _Flowers_ pale ampare-purple to light

haryense-violet (R.C.S.). _Perianth-tube_ 1·1-1·5 cm. long, 4 mm. in

diameter, cylindrical, slightly inflated at the base; lobes 1-1·1 cm.

long, 3-5 mm. broad, elliptic or lanceolate, acute or obtuse.

_Corona-lobes_ 3, 1·5 mm. long, opposite the inner segments. _Stamens_

subsessile, in 2 whorls about halfway down the perianth-tube; anthers

sub-globose. _Ovary_ sessile, sub-globose; style 2 mm. long, thick;

stigma capitate.

The specimen figured was first mentioned in the _Gardener’s Chronicle_,

1892, as _Calla Pentlandii_, and two years later in the same publication

was again brought to notice as _Richardia Pentlandii_, under which name

it was described and figured in the _Botanical Magazine_. Mr. N. E.

Brown, who monographed the genus for the _Flora Capensis_, considers it

the same as _Richardia angustiloba_ which was described as early as

1865. It was introduced into cultivation by Mr. R. Whyte, Pentland

House, Lee, who raised flowers in 1892, and exhibited it at a meeting of

the Royal Horticultural Society and was awarded a first-class

certificate.

Specimens of the tubers were taken to Kew by Mr. E. E. Galpin in May,

1892.

Our present illustration was made from plants flowered by Mr. H. H.

Wickens, Officer in Charge of the Union Buildings Garden, Pretoria.

DESCRIPTION:--_Leaves_ dark green, unspotted; petiole 30-60 cm. long,

terete, glabrous; lamina 22-30 cm. long, 11 cm. broad at the widest

part, ovate, acute, and produced into a filiform appendage at the apex

1·2 cm. long, sagittate at the base, glabrous, with the midrib prominent

beneath and channelled above. _Peduncle_ over 1 metre high, longer than

the leaves, terete, glabrous. _Spathe_ gamboge-yellow, dark purple at

the base inside, 10-14 cm. long, 4-4·5 cm. broad across the middle, 7-10

cm. across the mouth, loosely convolute for two-thirds of its length,

then expanding into a broad, nearly horizontal limb produced into a

subulate tip 1·5 cm. long and with recurved margins. _Spadix_ yellow,

4·5 cm. long, cylindrical. _Ovaries_ with subsessile stigmas, pale

greenish-white. _Staminodia_ none; anthers yellow. _Calla Pentlandii_,

* * * * *

According to the _Flora Capensis_ the only species in the genus

_Freesia_ is _F. refracta_, Klatt, which is a native of the eastern

districts of Albany, Bathurst, etc., and is characterised by having

(among other characters) the slender lower part of the perianth-tube

shorter than the upper broader part and not more than twice as long as

the bracts. But there are at least three other species found in other

regions that distinctly differ in habit or in the tube of the flower or

in both. One of them collected by Burchell in Bechuanaland and at

present undescribed, has a very long tube. Another is a plant found in

the coast districts of Swellendam, Riversdale, Ladismith, etc., figured

and described by Thunberg under the name of _Gladiolus Sparrmanni_, upon

which I found the species _Freesia Sparrmannii_. The reference to this

figure is omitted by Schultes in his edition of Thunberg’s _Fl. Cap._,

and is not quoted by Baker, but it accurately agrees with the plant

Zeyher collected along the Buffeljagts River in Swellendam Division and

distributed under No. 4027. It conspicuously differs from _F. refracta_

by the very much longer slender part to the perianth tube, and although

Thunberg’s plant and that collected by Zeyher have purplish-tinted

flowers, I place the plant here figured as a yellow variety of it,

because I find that the late P. MacOwan, in a letter preserved at Kew,

gives the following particulars concerning this species, which he also

considers distinct from _F. refracta_. He writes: “All along the coast

from Cape Point towards Agulhas, notably near Mossel Bay, the other

_Freesia_ grows wild. I have never seen it in my Eastern Province

peregrinations.... Its colour varies very much, from pale golden

daffodil tint to pure white, and is either with or without purplish

stains on the outside of the perianth-segments. Here, at the Hort.

C.B.S., we paid much attention to this lovely bulb, grew it year after

year, roguing out all the yellow and purple-stained individuals and

sowing the whitest. This is the ‘_Freesia refracta alba_’ of gardens.”

This note gives the origin of _F. refracta_ var. _alba_, Baker, _Handb.

Irid._ p. 167, which should now be called _F. Sparrmannii_ var. _alba_,

for it certainly is not the same as the true _F. refracta_, and

Thunberg’s original name must be upheld.

The plant here figured is doubtless the pale golden form mentioned by

MacOwan, and it differs from the yellow-flowered _F. xanthospila_ by the

very long slender part of its perianth-tube.--N. E. BROWN.

Our illustration was made from specimens grown in the Gardens of the

Division of Botany from bulbs presented by Mr. J. Shand, of Ladismith,

Cape Province.

DESCRIPTION:--_Corm_ about 4 cm. long, 3 cm. in diameter, produced into

a short neck and densely covered with fibres. _Leaves_ basal, 6-8 cm.

long, ·5-1 cm. broad, acute, somewhat sheathing at the base, glabrous.

_Peduncle_ 9·5 cm. long, with the upper portion bent at a right angle.

_Spathe-valves_ 1 cm. long, ovate, subacuminate, acute, membranous in

the upper portion. _Perianth-tube_ 5·2 cm. long, 1·2 cm. in diameter

above, campanulate in the upper portion and becoming slenderly tubular

in the lower half, yellow; lobes 1·2 cm. long, 1 cm. broad,

ovate-oblong, or subrotund, rounded above, yellow. _Style_ 5-6 cm. long,

filiform, 6-lobed; lobes 5 mm. long, linear, somewhat spathulate at the

apex.--E. PERCY PHILLIPS.

Among rock plants there are few which equal this fine _Crassula_ for

brilliant colouring. It is easy to propagate and flowers freely. The

species is common in the Eastern Province, and is found in flower during

the month of June. The specimen from which our illustration is made was

collected by Mr. P. J. Pienaar at Grahamstown and flowered in the

Gardens of the Division of Botany.

DESCRIPTION:--_Stem_ succulent, 30-55 cm. high, simple. _Leaves_ connate

at the base, fleshy, 6-9 cm. long, 1·5-2·5 cm. broad, decreasing in size

upwards, obliquely falcate, obtuse, glaucous. _Peduncle_ reddish in

colour. _Inflorescence_ a dense trichotomous cyme. _Calyx-lobes_ 3 mm.

This species, indigenous to Natal, represents only one of many of our

native plants, which have been brought to the notice of horticulturists

by English Nurserymen. A living plant was exhibited at a meeting of the

Horticultural Society in February 1854 by Messrs. Backhouse, who

imported the plant from Natal. The specimen from which our illustration

was made was collected by Miss K. A. Lansdell at Ifafa on the South

Coast of Natal. The species is a shade lover, and is usually found

flowering in the shelter of rocks and trees. The size and number of the

flowers have been much improved by cultivation, and several hybrids have

been raised from the species. The flowers may vary in colour from a red

to a yellowish-red.

DESCRIPTION:--_Rootstock_ a fleshy rhizome, 1·5-2 cm. in diameter, with

numerous fleshy cylindrical roots. _Leaves_ many, 40-50 cm. long, 5-6·5

cm. broad, strap-shaped, acute, slightly narrowed at the base, the leaf

bases forming a distinct swelling just above the rhizome, glabrous,

bright green. _Peduncles_ shorter than the leaves, compressed, sharply

2-edged. _Inflorescence_ a 12-20-flowered umbel. _Spathe-valves_ 4 cm.

long, 7-8 mm. broad, ovate-oblong, membranous. _Floral bracts_ 2·5 cm.

long, linear. _Flowers_ erect. _Perianth_ divided almost to the base;

tube about 5 mm. long; segments 5-7 cm. long; the inner 1·1 om. and the

outer 1·8-2·1 cm. broad at the widest part, oblanceolate; the inner

emarginate; the outer minutely thickened at the apex; all obtuse,

gradually narrowed to a claw; bright red, with white margins at the

lower half. _Stamens_ included; filaments compressed; anthers linear,

versatile. _Ovary_ 5-6 mm. long; ellipsoid, bluntly 3-angled; style

slender, as long as the perianth; stigma trifid, sometimes bifid.

_Fruit_ a bright red berry, globose, 1·5 cm. in diameter. _Seeds_ 1 or

few, subglobose.

This handsome plant is a shrub or sometimes becomes a small tree, and is

without doubt one of our finest native flowering shrubs. It is common in

Natal, where it flowers in early spring and summer. The large fragrant

bell-shaped flowers are produced in great profusion and give to the

plant a very striking appearance. The species has been known to European

cultivation for over sixty years, but is usually grown in the

greenhouse. It is frequently seen in gardens in Durban, Natal, and

specimens have been grown in Queens Park, East London, but the plant has

not received the attention from South African horticulturists which it

deserves.

Our illustration was made from specimens collected by Miss K. A.

Lansdell in the Stella bush near Durban, Natal. The native name is

“Isi-Qoba.”

DESCRIPTION:--A _shrub_ or small tree. _Branches_ with dark-coloured

bark, glabrous. _Leaves_ opposite; petioles 3-5 mm. long; blade 5-15 cm.

long, 2-3·5 cm. broad, lanceolate or sometimes oblanceolate, obtuse or

acute, gradually tapering to the base, entire, with a prominent reddish

mid-rib beneath, glabrous; stipules about one-third of the length of the

petiole, ovate, acuminate, minutely pubescent, soon deciduous. _Flowers_

terminal, axillary or clustered. _Pedicels_ 1-2 mm. long, minutely

pubescent. _Calyx_ 3-4 mm. long, minutely pubescent and glandular

without, silky within; tube campanulate; lobes acute. _Corolla_ white,

usually with 5 faint pink lines within, which may become darker near the

base and broader on the lobes, sometimes spotted; tube 2-5 cm. long, 1-8

cm. in diameter above, campanulate, suddenly constricted and narrowed

above the calyx, minutely pubescent without, densely tomentose within;

lobes spreading, half as long as the tube. _Anthers_ linear. _Ovary_

1-celled, with numerous ovules; stigmas white or pink. _Fruit_ a brown

berry, crowned with the persistent calyx-lobes, many seeded. _Seeds_

minute, immersed in the fleshy parietal placentas.

This species was first collected by the traveller Rehmann and described

by Engler in 1883 as _Zantedeschia Rehmanni_. Among English

horticulturists the plant attracted a lot of attention, and was several

times referred to in the _Gardener’s Chronicle_. The chief attraction to

cultivators is the deep red colour of the spathes, but when grown in

English gardens and also in its native climate, the colour varies

considerably. Dr. Medley Wood notes that at the Natal Herbarium, Durban,

the original deep red colour returned to the plants after being

cultivated fifteen years. This loss of colour, however, does not appear

to be constant among plants which flowered for the first time at the

Division of Botany Gardens, Pretoria, from tubers which were sent by S.

G. Marwick, Esq., Assistant Commissioner, Hlatikulu, Swaziland. In these

the colour ranged from pale pink to deep red. After fertilization,

however, and during the formation of the fruits the colour gradually

fades from the spathes and they become green. The species was introduced

into England by Mr. R. W. Adlam of Natal, who sent tubers to the

Cambridge Botanic Gardens. The leaves vary from a uniform green to green

with white markings, or green with darker green markings.

Our illustration was made from specimens cultivated at the Natal

Herbarium, Durban, Natal.

DESCRIPTION:--_Plant_ about 0·5 metre high. _Leaves_ 3-5, the lower

reduced to mere sheaths; petiole 15-30 cm. long, deeply channelled down

the face, rounded on the back, stem-clasping at the base; blade 40-60

cm. long, 6-8 cm. broad, lanceolate, acute, with a subulate point,

narrowed at the base into the petiole, entire, with undulating margins,

and the mid-rib prominent beneath, dark green, sometimes with white,

sometimes with green markings, shining. _Peduncle_ shorter than the

leaves, terete, glabrous, olive-green. _Spathe_ 10-15 cm. long, with a

tube 4-5 cm. long and 1·8-2 cm. in diameter, with an ovate acuminate

limb, varying in colour from almost white to a deep rose or aster purple

(R.C.S.) in the upper portion, greenish-yellow below, without a dark

blotch round the base of the spadix. _Spadix_ stout, with male flowers

on the upper half and female flowers on the lower half. _Ovary_

glabrous; stigma sessile. _Fruit_ a berry. _Seeds_ subglobose.

The specimen from which our illustration was made is growing in the

Gardens of the Division of Botany, Pretoria, and was presented by Mr. A.

E. Antrobus, Cloud’s End, Louis Trichard, in the Zoutpansberg District.

The flowers appeared in September before the leaves, which only made

their appearance the following month. The species does very well on a

rockery, and when it flowers is a very pleasing sight.

DESCRIPTION:--A plant with a very large tuber just below the

ground-level and from which the branches spring. _Branches_ more or less

succulent, glabrous. _Leaves_ appearing after the flowers, sub-sessile,

3·5-9 cm. long, 1·5-6·5 cm. broad, obovate, obtuse, narrowed to the

base, dark green and very shiny above, pale green and dull beneath, with

the mid-rib and lateral veins distinct above, the mid-rib alone

prominent beneath. _Inflorescence_ cymose, up to 5-flowered, terminal.

_Sepals_ lanceolate, pilose. _Corolla-tube_ about 3 cm. long, 1·2 cm.

broad above, tubular below, pilose without and within on the broadened

portion; lobes, 1·7-2·5 cm. long, about 1 cm. broad, elliptic-oblong, or

obovate, shortly acuminate, acute, with crinkled edges, usually sparsely

pubescent on the upper portion, pink, with dark red margins. _Anthers_

This species was first collected by Mr. P. J. Pienaar at Smit’s Drift,

near Pietersburg, in January 1914, where it is very common on and around

the isolated granite kopjes, though it also occurs in the open flat

country. A number of plants were obtained for the gardens of the Union

Buildings at Pretoria, where they have been established, and specimens

are also growing in the Aloe collection at the Division of Botany

Gardens, Pretoria. The species flowers from May to July.

DESCRIPTION:--_Herb_, succulent, stemless. _Leaves_ 35-60 in

a dense rosette, 60-80 cm. long, 12-15 cm. broad at the base,

lanceolate-ensiform, acute, reddish-green or blueish, beset along the

margins with small chestnut-coloured (R.C.S.) deltoid thorns 2 mm. long

and 5-7 mm. apart. _Inflorescence_ 2-3 from the same rosette, copiously

panicled, erect, 1·25-1·65 metres high, with about 8 arcuate-erect

branches subtended at the base with deltoid-acuminate bracts; racemes

densely flowered, 25-35 cm. long, cylindrical-conical. _Bracts_ at first

densely imbricated, afterwards embracing the pedicels, 20 mm. long, 11

mm. broad, broadly ovate-acuminate, acute, many-nerved. _Pedicels_

erect, spreading, 15-20 mm. long, greenish-scarlet. _Perianth_ 35-38 mm.

long, somewhat 3-angled and cylindrical, at first scarlet, greenish at

the tips, becoming citron-yellow (R.C.S.) when open; outer segments

shorter than the inner, free, acute; inner slightly recurved at the apex

and more obtuse, and the lateral ones becoming compressed towards the

apex so as to close the mouth of the tube. _Stamens_ just exserted;

filaments bright chalcedony-yellow (R.C.S.); anthers grenadine-red

(R.C.S.). _Capsule_ enclosed within the dry perianth, 20 mm. long,

cylindrical-trigonous, woody. _Seeds_ 4-5 mm. long, irregular, narrowly

winged.

This handsome _Aloe_ occurs on the northern slopes of the hills around

Pretoria, and is especially abundant on Meintjes’ Kop. It is also found

near Lydenburg, at Barberton, the Premier Mine, and along the foot of

the Lebombo range of mountains. The flowers usually appear in May, and

when in flower the plants attract large numbers of brightly coloured

sun-birds. The tall branched inflorescence forms the most striking

feature of the plant, and when one compares it with that of _Aloe

lineata_, which is unbranched and differs in many other important

respects, it seems almost incredible that _A. pretoriensis_ should have

been mistaken by so many botanists for _A. lineata_ as has been done.
