846 ASCLEPIADE (Brown). [ Brachystelma. 
base, nearly or quite glabrous elsewhere ; corolla rotate, entirely 
glabrous and not ciliate, yellow according to Hutton, but the dried 
flowers appear to be dark purple-brown with the very small tube 
yellowish ; tube } lin. long, 1 lin. broad, cup-like ; lobes free, widely 
spreading, 14 lin. long, not quite 1 lin. broad, linear or oblong- 
linear, shortly acute, with reflexed margins; outer corona cup- 
shaped, with 5 pairs of erect linear obtuse teeth } lin. long, 
overtopping the staminal column, glabrous, apparently yellow, with 
darker (green?) tips to the teeth ; inner corona-lobes scarcely 4 lin. 
long, linear, obtuse, closely incumbent on the backs of the anthers 
and not exceeding them, with a partition at their base dorsally 
connecting them with the outer corona, apparently yellow. Decaceras

The specimen figured by Harvey is much dwarfer than those at Kew. The 
‘minutely bidentulate’’ interspaces between the pairs of corona-teeth I have 
observed in one flower, but think it due to the tissue having been torn. 
13. B. flavidum (Schlechter in Engl. Jahrb. xl. 94); tuber 
depressed, up to 13 in. in diam. ; stems several (?), branching, about 
2 in. high, slender, puberulous, laxly leafy ; leaves erectly spreading, 
not fully developed at the time of flowering, subsessile, up to 7} lin. 
long, 14-2 lin. broad, lanceolate-elliptic, acute, subglabrous ; flowers 
few together in fascicles at the nodes; pedicels 2 lin. long, filiform, 
puberulous; sepals scarcely 14 lin. ‘long, lanceolate, acuminate, 
puberulous ; corolla 24 lin. long, lobed to % of the way down, 
entirely glabrous, yellowish ; lobes free, spreading, long-acuminate 
from an ovate base ; corona-lobes connate high up, 3-lobed, with the 
lateral lobes minute, ciliate, and the middle lobe larger, ligulate, 
obtuse, incurved, glabrous. 
Eastern Region: Natal; Alexandra County, at Fairfield, 2200 ft.,

Said to be allied to B. caffrum, N. E. Br., and B. pulchellum, Schlechter, but 
distinguished by its more pointed corolla-lobes and different corona. 
14. B. caffrum (N. E. Br. in Gard. Chron. 1894, xvi. 62); tuber 
depressed-globose, with a long neck, dividing into numerous pro- 
cumbent branching minutely scaberulous stems 2—5 in. long ; leaves 
2-8 lin. long, including the very short petiole, }-4} lin. broad, 
mostly ovate or the upper lanceolate and some of the basal orbicular- 
ovate, acute, rather thick, glabrous, minutely and stiffly ciliate, with 
the midrib beneath scaberulous, more rarely with the undersurface 
slightly scaberulous ; flowers solitary or rarely in pairs at the nodes ; 
pedicels 4-1} in. long, slender, erect, scaberulous ; sepals 3-1 lin.
