11. C. simulans (N. E. Br.) ; stems erect, closely placed, branching 
at the base, 4-angled, 2-3 in. high, 5-7 lin. square, with flattish 
sides and acute angles with horizontally spreading conical acute 
hard pointed teeth 1-1} lin. long, glabrous, green or tinted with 
purple-brown, slightly glaucous, bearing several flower-cushions 
along the sides, apparently producing a succession of single flowers 
during more than one year; pedicels 2-4 (in fruit 6-8) lin. long, 
slender, erect, about 2 lin. thick, glabrous; sepals ? lin. long, 
extending to the sinuses of the corolla, lanceolate or ovate-lanceolate, 
acute, glabrous; corolla 34 lin. in diam., deeply lobed, rotate, 
without a distinct tube ; lobes more or less recurving, 1} lin. long, 
1 lin, broad, ovate or ovate-lanceolate, acute, slightly thickened at 
the apex, glabrous and smooth on the back, smooth on the inner 
face, but thinly sprinkled with erect rather long hairs on the basal 
half and with a few minute hairs at the tips, light yellow (Marloth) ; 
outer corona-lobes erect, $—3 lin. long, linear, deeply bifid, with 
slender diverging teeth ; inner corona-lobes closely incumbent upon 
the backs of the anthers and shorter than them, with the inflexed 
part about } lin. long, linear-oblong, obtuse, having a transverse 
ridge on the back at the bend; follicles about 34 in. long, erect, 
subparallel, slender, about 14-2 lin. thick, linear-terete, acute, 
smooth, glabrous ; seeds 2-2} lin. long, scarcely 1 lin. broad, ovate,

This species is very closely allied to C. arida, N. E. Br., but differs from the 
latter (according to Masson’s figure and description of it) in having much smaller 
flowers, without spots at the base of the lobes and with hairs at the base as well 
as at the tips of the lobes. 
12. C. Hottentotorum (N. E. Br. in Hook. Ic. Pl. under t. 1903) ; 
plant 4-6 in. high, branching at the base; branches obtusely 
4- (rarely 5-) angled, }—1 in. square exclusive of the teeth, glabrous, 
-greyish-green or purplish-tinted 
; teeth 2-3 lin. long, stout, conical, ==
