_Primary leaves_ with long petioles, which, after the blade falls off,
are hardened so as to form thorns 1·5-4 cm. long; lamina 1-1·6 cm. long,
5-9 mm. broad, obovate, cuneate at the base, retuse or sometimes
3-toothed at the apex, glaucous, glabrous; secondary leaves arising in
the axils of the primary leaves, sessile or sub-sessile, obovate,
cordate at the apex, cuneate at the base, entire. _Stipules_ 2 mm. long,
ovate-lanceolate, usually ciliate, deciduous. _Sepals_ 1·2 cm. long, 6
mm. broad, obovate-oblong, obtuse, bluntly mucronate and shortly bearded
at the apex, with membranous margins, concave, glabrous. _Petals_ 2·2
cm. long, 1·6 cm. broad, obovate, somewhat truncate at the apex,
glabrous, ciliate on the cuneate base. _Stamens_ 15, of two different
lengths; the filaments of the 10 shorter stamens not equalling the
styles, 7 mm. long, linear, tapering to the apex, ciliate below; the
filaments of the 5 long stamens exceeding the styles, 1·2 cm. long;
anthers 2 mm. long, oblong. _Ovary_ 3 mm. long, obovate in outline,
silky; styles cohering, 6 mm. long, silky; stigmas 5, 2 mm. long,
subterete, obtuse. _Carpels_ 1 cm. long, produced into a long awn
densely pilose in the upper half.

FOOTNOTES:
[A] NOTE.--Having been asked by Dr. Pole Evans to see the proofs of the
first sheets of this new work through the press, he empowered me to
make any change of nomenclature that might be necessary. For owing to
the want of types and some of the rarer books at Pretoria, it is not
always possible to make correct identifications there. From this cause
the plants represented upon Plates 3 and 4 were misidentified, and the
names “_Arctotis decurrens_” and “_Cyrtanthus angustifolius_” already
printed upon the plates before they came into my hands for verification
and found to represent new species. I have therefore substituted new
names for these two plants, and have added Latin descriptions compiled
from the drawings and Dr. Phillips’ English descriptions, which have
not been altered.
It may not be out of place to state that the true _Arctotis decurrens_,
Jacq. (which this species was supposed to be), differs by the basal
leaves having usually only one small lobe or (grown under the condition
of much moisture in a rich soil) two lobes on each side, and an
elongated ovate oblong terminal lobe twice or more than twice as long
as broad; the branching stem and peduncles have small entire leaves
scattered along them; the ray florets are without a yellow spot at the
base, and the pappus-scales are truncate (not pointed) at the tips.--N.
E. BROWN.
[B] As stated under Plate 3, this plant had been supposed to be a
form of _C. angustifolius_, and that name has unfortunately been
printed upon the plate. It proves to be an entirely new species, well
characterised by the very slender curved basal part of the flower-tube,
and the long, tapering and very acute tips of the leaves, which are
narrowed at the base into terete petioles, and also, to judge from the
figure, are not produced at the same time as the flowers. In the true
_C. angustifolius_, Aiton, the flowers and leaves are produced at the
same time, the latter are flat to the base and very shortly pointed at
the tips; the tube of the flower gradually narrows from apex to base
without being contracted into a very slender basal part, and is less
curved there.
There is a large-flowered variety of _C. angustifolius_ known as var.
_grandiflorus_, Baker, which does not seem to be clearly understood in
South Africa. A good figure of it, but reduced in size, appears in the
_Gardeners’ Chronicle_, 1905, vol. 37, p. 261, f. 110, No. 2.--N. E.
BROWN.
[C] NOTE. Although mistaken in South Africa for an allied species, this
pretty bulb differs from all the other small-flowered species in the
genus by its broad linear-lanceolate leaves, and the broadly elliptic
or suborbicular perianth-lobes, which have suggested the specific
name to me. In all the other species the perianth-lobes are oblong or
elliptic-oblong. My description is compiled partly from the English
description of Dr. Phillips and partly from a dried specimen.--N. E.
BROWN.
[D] NOTE.--As Dr. Phillips has compared this plant with _S. Burmanni
Sweet_, I would like to point out that it is very doubtful if the _S.
Burmanni_ of the _Flora Capensis_ and the specimens in Herbaria so
named, really represent the plant figured by Burmann, upon which that
species was founded. Burmann (_Rar. Afr. Pl._ p. 7, t. 31) represents
a plant with stems about half as thick as those of _S. rigidum_,
constricted into short globose joints, with crenate (not entire)
leaves and small flowers, of which he does not state the colours. I am
doubtful if this plant is at present correctly represented in Herbaria.
It may also be well to point out that although the authority for the
genus _Sarcocaulon_ and the species _S. Burmanni_ and _S. Heritieri_
are attributed to De Candolle in the _Flora Capensis_ they should be
credited to Sweet, since De Candolle described them both as species
of _Monsonia_ under the section _Sarcocaulon_, which Sweet rightly
recognised as a distinct genus.
