ALOE, _Linn._; _Benth. et Hook. f. Gen. Plant._ vol. iii. p. 776.
=Aloe saponaria=, _Haw. Syn._ 83; _Fl. Cap._ vol. vi. p. 312.
This Aloe, known as the common soap-aloe, was introduced into
cultivation in Europe early in the eighteenth century, and it still
retains its popularity. Three colour varieties are known: one with
salmon-coloured flowers, one with red flowers, and one with pale
lemon-yellow flowers. The inflorescence in all these varieties may be
either simple or branched. The plants are common on the south and east
coasts of South Africa.
The buds just before the flowers open are between 3 and 4 cm. long, and
in about four days are completely open, and then a little over 4 cm.
long. The stamens do not all ripen at the same time; two or three
project and shed their pollen, being followed after a short interval by
the remainder. While the stamens are dehiscing the style remains within
the perianth and lengthens only after the pollen has been shed. It then
projects beyond the perianth, which now begins to wither and close
tightly round the style. While this is taking place the filaments
contract by twisting and are drawn back into the perianth. The inclusion
of the style during the dehiscence of the anthers and its subsequent
projection ensures cross-pollination.
Our plate was prepared from specimens growing in the Aloe collection at
the Division of Botany, Pretoria.
DESCRIPTION:--An acaulescent plant or with a short stem with a rosette
of leaves. _Leaves_ up to 20 cm. long, about 8 cm. broad, dark green
with dark longitudinal marking on the upper surface, lighter green and
faintly spotted beneath, acuminate, usually brown and withered at the
tip, with spines on the margins; spines 8 mm. long, about 1·5 cm. apart
and more or less at right angles to the leaf. _Inflorescence_ ·3-·5 m.
high, simple or branched. _Peduncle_ terete with a few dry membranous
acuminate bracts. Flowers in a contracted raceme. _Floral bracts_
1·5-2·5 cm. long, long-acuminate from an ovate-lanceolate base.
_Pedicels_ 2·5-4 cm. long, terete. _Perianth-tube_ 3·3 cm. long, 9 mm.
in diameter above, gradually narrowing below and dilated into a globose
base; segments 1 cm. long, ·5 cm. broad, oblong, obtuse, slightly
reflexed in the mature flower. _Filaments_ in buds 2·4 cm. long, linear,
in mature flowers lengthening to 3·5 cm. and becoming corrugated in the
upper half. _Ovary_ 8 mm. long, cylindric; style 2·5 cm. long,
cylindric, lengthening in older flowers to 3·8 cm.; stigma simple

=Synnotia Metelerkampiae=, _L. Bolus_ in _Annals Bolus Herb._ vol. iii. p. 77.
The genus _Synnotia_ is one of the endemic genera of the family
_Iridaceae_, and has hitherto only been represented by two species. The
species here figured is a new record for the genus in South Africa. On
Plate 60 we figured a species of _Sparaxis_, and a comparison of that
plate with the present one will show that the two genera _Sparaxis_ and
_Synnotia_ are nearly related: the rootstock, inflorescence, and spathe
valves are the same in both, but the former has regular flowers, while
in the latter genus the flowers are irregular.
The species is found near Eendekuil in the Clanwilliam Division, and the
original description was prepared from specimens flowering in the garden
of Mrs. F. Metelerkamp. We are indebted to the Curator of the Bolus
Herbarium for lending us the illustration from which the accompanying
plate was prepared.
DESCRIPTION:--A glabrous herb, 16-25 cm. high. _Corm_ 1·6 cm. long, 1·2
cm. in diameter, ovoid, with rigid tunics prominently nerved and with
the nerves reticulated. _Stem_ erect. _Leaves_ 6-7 to each stem, 5-8 cm.
long, 1-1·2 cm. broad, equitant, adscending, linear, obtuse, apiculate
or acute, with inconspicuous nerves. _Inflorescence_ racemose, laxly
9-12-flowered, with the flowers almost erect. _Bracts_ clasping,
about 2 cm. long, ovate; bracteoles united beyond the middle,
setaceous-acuminate, almost equalling the bracts. _Perianth-tube_ 4-4·5
cm. long, 1-2 mm. in diameter, oblique and expanding to 7 mm. in
diameter above; segments unequal; the lower smaller than the upper; the
outer segments 1·2 cm. long, 4-6 mm. broad, ovate-oblong, subacute; the
inner segments subclawed, obtuse, and with obscurely undulate margins;
the uppermost 1·4 cm. long, 8 mm. broad, ovate; the lower 5 mm. broad.
_Filaments_ 1·2 cm. long; anthers 3-5 mm. long, with purple pollen.
_Style_ 4·6 cm. long with spathulate branches 3 mm. long. _Capsule_ 1·5
cm. long. _Seeds_ many, 2 mm. in diameter, subglobose (Bolus Herb. Cape

=Chrysophyllum magalismontanum=, _Sond. in Linnaea_, vol. xxiii. p. 72;
_Fl. Cap._ vol. iv. sect. 1, p. 437.
The genus _Chrysophyllum_ is a small genus in South Africa, having only
three representatives, two in Natal and one in the Transvaal. The
species figured here is the common one in the Transvaal, being found all
along the rocky outcrops of the Magaliesberg range and known as “stam
vrucht,” because the fruits are borne on the old stems. The fruits,
which are oval in shape, are somewhat larger than a cherry, and are used
to make preserve. The plants flower in October and ripe fruits are
formed in January. A milky juice characteristic of all the species in
the _Sapotaceae_ is present in the plant. A member of the order,
_Mimusops balata_, Crueg, native of Guiana, yields a guttapercha
(balata).
The specimens from which our illustration was made were gathered at
Eloff’s Cutting near Pretoria by Mr. D. J. Fouche.
DESCRIPTION:--A bush. _Youngest_ branchlets rufo-tomentose, at length
becoming pubescent. _Leaves_ petioled; blades 3-9 cm. long, 1·6-4·4 cm.
broad, oblong-obovate or oblong, retuse at the apex, slightly narrowed
at the base, dark green above, rufo-tomentose beneath on young leaves,
becoming greyish tomentose on the older leaves; petiole 1 cm. long,
pubescent. _Flowers_ arising on the old wood. _Pedicels_ 2 mm. long,
rufo-tomentose. _Sepals_ unequal 2·5-3 mm. long, 2-3·5 mm. broad, ovate,
obtuse; the 3 outer longer than the 2 inner and densely rufo-tomentose.
_Corolla-tube_ 1 mm. long; lobes 2·5 mm. long, ovate, obtuse.
_Filaments_ 1·5-2 mm. long, terete, glabrous; anthers 1 mm. long, oblong
in outline. _Ovary_ 2 mm. in diameter, villous, gradually passing into
the 1·5 mm. long style; stigma terminal, simple. _Fruit_ 2·5 cm. long,
1·7 cm. in diameter, ellipsoid, dark-red when ripe (National Herb.
Pretoria 2636).

=Cyrtanthus helictus=, _Lehm. Delect. Sem. Hort. Hamburg_. 1839, 7; _Fl.
Cap._ vol. vi. p. 226.
This species of _Cyrtanthus_ belongs to the same group as the species
figured on Plate 25 (_C. sanguineus_). The group is characterised by
having a single flower or few flowers in each umbel. Our previous
illustrations of _Cyrtanthus_ should be compared with the above two and
the present plate. _C. helictus_, which is an exceptionally graceful
representative of the genus, has not been extensively collected by
botanists, and we know of its occurrence in the Somerset East, Graaff
Reinet, Fort Beaufort, and Queenstown Divisions only. It should
certainly engage the attention of cultivators of South African plants,
as it is well worthy of a place in the bulb garden.
Our illustration was made from specimens collected by Dr. E. P. Phillips
near Fort Beaufort; these flowered at the Division of Botany in November
1922.
DESCRIPTION:--Bulb 2·7 cm. in diameter, globose, with papery tunics and
thick wrinkled roots from the base. _Leaves_ contemporary with the
flowers, about 3 to each bulb, spirally twisted, 12 cm. long, 4·5 mm.
broad, linear, obtuse, narrowed to the base, glabrous. _Peduncle_
arising at side of the leaves, 9 cm. long, but sometimes longer, terete,
glabrous. _Spathe_ valves 2·5 cm. long, acuminate from an ovate base,
membranous. _Flowers_ usually solitary. _Pedicel_ 1·2 cm. long, terete,
glabrous, shorter than the spathe-valves. _Perianth-tube_ 3 cm. long, 2
mm. in diameter, and curved at the base, widening to 1·3 cm. in diameter
at the throat; lobes 2 cm. long, 9 mm. broad, obovate, obtuse, or the
outer segments bluntly apiculate with a pendulous appendage, 5-nerved.
_Stamens_ in 2 series: the lower with filaments 1·1 cm. long; the upper
with filaments 8 mm. long, all filiform; anthers 3·5 mm. long, linear.
_Ovary_ 7 mm. long, ellipsoid, glabrous; style 5·5 cm. long; lobes 5 mm.
long, linear (National Herb. Pretoria 2634).

aristae laterales 1·8 cm. longae, villosae, media 1·5 cm. longa.
_Stamina_ 8 mm. longa, linearia, apice glandibus linearibus
instructa. _Ovarium_ pilis longis vestitum; stylus 6 cm. longus;
stigma 6 mm. longum.
This species of _Protea_ was collected early in 1921 by Mr. T. P.
Stokoe. At the time there was some doubt about its identity, and it was
provisionally placed under _P. speciosa_. Recently we received more and
better material from the same collector, and have no hesitation in
describing it as a species allied to _P. speciosa_. It differs from this
species in having shorter tufts of hairs at the apices of the involucral
bracts and the awns of the perianth are much longer and subequal. The
species belongs to a section of the genus _Speciosae_, which is
characterised by having the inner involucral bracts fringed with long
hairs or bearded. A comparison should be made with Plates 22, 76 and 84,
which illustrate examples of other sections of the genus.
The first specimens collected by Mr. Stokoe came from an isolated krantz
on a peak directly opposite Kogelberg on the land side, and subsequently
he found specimens also on high peaks facing Kogelberg, but on the
seaward side. It probably does not occur lower than an altitude of 3000
ft. The plant is a spreading bush about 6 ft. high (not so compact as
_P. speciosa_), and grows with such moisture-loving plants as _Mimetes
hottentotica_ and _M. splendens_. The young leaves have a fringe of
longish white hairs.
DESCRIPTION:--_Branches_ glabrous. _Leaves_ 7-9 cm. long, 3-4 cm. broad,
obovate, obovate-oblong, more rarely elliptic-lanceolate, rounded and
slightly emarginate at the apex, slightly narrowed to the base,
leathery, with reddish margins, quite glabrous. _Head_ sessile, 10-11
cm. long, 5·5 cm. in diameter. _Involucral bracts_ 9-10-seriate; the
outermost 1·5-2 cm. long, ovate-oblong, rounded at the apex, densely
silky pubescent, ciliate with white hairs with a small tuft of brown
hairs at the apex; the innermost 9 cm. long, 2·5 cm. broad above,
spathulate, silky pubescent, except at the base, with a fringe of
dark-brown hairs at the apex about 3 mm. long. _Receptacle_ 2 cm. long,
conical. _Perianth-sheath_ 5·5 cm. long, dilated and 3-keeled below,
glabrous; lip 1·2 cm. long, shortly but densely villous, 3-awned;
lateral awns 1·8 cm. long, linear, acuminate, shortly but densely
villous, tipped with a few brown hairs; median awn 1·5 cm. long,
otherwise similar. _Stamens_ all fertile; anthers 8 mm. long, linear,
with a pink linear apical gland. _Ovary_ covered with long, golden-brown
hairs; style 6 cm. long, subterete, slightly curved, very sparsely
pilose below; stigma 6 mm. long, linear; scarcely bent at junction with
style (Type in National Herb. Pretoria, No. 2632).

=Greyia Radlkoferi=, _Szyszy. Pl. Rehmann._ vol. ii. p. 49 (1880).
An extremely ornamental shrub found in the eastern Transvaal, where it
has been recorded from Waterval Onder, ’Thlatikulu and Barberton. The
plant does quite well at Pretoria, where specimens have been planted on
Meintjes Kop behind the Union Buildings.
The genus _Greyia_, which contains only three known species, was named
in honour of Sir George Grey, K.C.B. In South Africa it has a very
limited distribution, and is interesting botanically, as there are still
some doubts as to its affinities.
In the Transvaal the plant flowers from July to October, the young
leaves appearing at the same time as the scarlet flowers. The flowers
are proterandrous, _i. e._, the pollen is shed before the pistil has
quite matured, and this makes self-pollination almost impossible.
The Cape species, _Greyia Sutherlandi_, is commonly known as “Baakhout”
or “Wild bottlebrush,” so that our plant might be appropriately named
the “Transvaal Baakhout.” The material from which our illustration was
made was gathered by Miss S. Gower on Meintjes Kop, Pretoria.
For a roller account of this interesting genus the reader is referred to
a paper by Dr. S. Schonland in the _Records of the Albany Museum_, vol.
iii. p. 40.
DESCRIPTION:--A shrub 2-5 m. high. _Branches_ with light-brown bark,
glabrous. _Leaves_ at the apex of the branches at the side of the
flowers; blade 3·5-12 cm. long, ovate, subacute, cordate at the base,
with lobed margins, sparsely pilose above with curled hairs,
white-tomentose beneath; petioles 2-10 cm. long, terete,
glandular-pilose. _Inflorescence_ of many inverted scarlet flowers.
_Bracts_ 7 mm. long, boat-shaped, glandular-pilose. _Pedicels_ 7 mm.
long, terete, glandular-pilose. _Calyx-tube_ 2 mm. long; lobes 5 mm.
long, oblong, shortly apiculate, sparsely glandular-pilose. _Petals_ not
all equal, 2-2·3 cm. long, almost 1 cm. broad, oblong-obovate, usually
rounded at the apex, more rarely emarginate. _Stamens_ usually 10,
sometimes 8, in two whorls; filaments 2·7 cm. long, terete; anthers 1·5
mm. long, ovate. _Disc_ cupular below with 10 or 8 arms from the rim of
the cup, each arm has a peltate disc. _Ovary_ about 1 cm. long, terete;
style 1·8 cm. long, terete; stigma simple. (National Herb. Pretoria, No.

vol. viii. Append, p. 6 (1791); Thunb. Fl. Cap. p. 412; Fl. Cap.
vol. ii. p. 405.
This curious _Mesembryanthemum_ was first collected by Carl Thunberg
between the Oliphants River and the Bokkeveld Mountains about 150 years
ago. Thunberg described his plant in 1789, and in his herbarium there is
one sheet with two perfect growths and two flowers upon it. Marloth
(_Flora of South Africa_, Pl. 49) figures a small portion of a plant
which, he states, was collected at Van Rhynsdorp by Mr. W. Spilhaus and
was as large as a child’s head. The specimens from which our
illustration was made were collected in the same locality by Mr. E. Rood
and sent to the Division of Botany, Pretoria.
The corpuscula, which are very succulent, show an extremely interesting
structure when examined in detail. If a longitudinal section is made, a
hard green central core is seen, which is the stem; this is surrounded
by long, crystalline cells, and the whole covered in by a juicy tissue.
As the green tissue is buried in the stem, it is very probable that the
crystalline cells referred to act as lenses and concentrate any light
which penetrates the outer tissue on to the chlorophyll-bearing cells.
The fleshy leaves are almost devoid of chlorophyll.
The flower is borne at the apex of the stem, but this can only be
satisfactorily seen in a longitudinal section. The crystalline cells are
continued round the base of the calyx.
DESCRIPTION:--Acaulescent plant with woody underground stems and fleshy
aerial stems and leaves. _Stems_ 2-3 cm. long, 2-2·5 cm. in diameter,
very succulent, glabrous. _Leaves_ two to each stem, usually one larger
than the other, 1·5-2 cm. long, 0·8-1·3 cm. in diameter, terete, blunt,
very succulent, glabrous. _Flowers_ white, arising from the apex of the
stems but appearing on a casual examination to come from the base of one
of the leaves, when expanded 1·2-1·5 cm. in diameter. _Petals_ in more
than one row; the outermost row connate into definite groups, 7 mm.
long, less than 0·5 mm. broad, linear, subacute. _Stamens_ in four rows;
filaments 1 mm. long, filiform; anthers about 1 mm. long, oblong.
_Calyx_ covered with crystalline cells; lobes almost membranous, 1 cm.
long, 3 mm. broad, oblong, or oblong ovate, obtuse. _Ovary_ sunk in
tissue of stem, 5-celled, with several stalked ovules with axile
placentation; upper portion of ovary cone-shaped tipped with five
terete, acute styles each 1 mm. long.

The genus _Brachycorythis_ is represented in Africa by over twenty
species, five of which occur in South Africa, and of these three are
endemic. The species described here is known from the Cape Province,
Natal, Zululand, Swaziland and the northern Transvaal, and extends into
tropical Africa. Its occurrence near Pretoria, in a totally different
botanical area, is therefore interesting. Harvey first described the
plant from specimens found near Durban by Mr. Sanderson, who stated it
was plentiful in the neighbourhood.
This attractive little orchid was collected by General the Rt. Hon. J.
C. Smuts on the farm Rietvlei No. 221, at Irene, near Pretoria, at an
altitude of about 5000 ft. above sea-level. The plant was found in open
grassland in deep red loam soil. It has large spreading finger-like
tubers and slightly scented flowers.
DESCRIPTION:--A herbaceous plant with long finger-like tubers about 1
cm. thick. _Stem_ with inflorescence up to 50 cm. high. _Leaves_ erect,
crowded 6 cm. long, 3·2 cm. broad at the base of the stem, becoming
smaller above, ovate, acuminate, shortly cuspidate, clasping at the
base, with the midrib prominent beneath, densely pubescent, with the
margins shortly ciliated and somewhat undulate. _Inflorescence_ up to 17
cm. long, racemose, many-flowered. _Bracts_ similar to the leaves but
smaller. _Upper sepal_ 5 mm. long, 3 mm. broad, elliptic, rounded above,
concave, sparsely pubescent without; lateral sepals 4 mm. long, 2·5 mm.
broad, oblong, unequal sided, rounded above, concave, sparsely pubescent
without. _Lateral_ petals 6 mm. long, 3·5 mm. broad, oblong, rounded
above, concave, unequal sided. _Lip_ 9 mm. long, 7 mm. broad, obovate,
3-lobed, the middle lobe smaller than the two lateral lobes, narrowed in
the middle and then expanded to form a deep pouch. _Anther cells_
parallel; pollinia granular, each attached to a separate gland.
