Central Karasberg. Stony plains south-west of Krai Kluft, 8587. 
An erect rigid glabrous branched shrublet, attaining 30 cm. in

to 20 cm. long, usually 7 — 9 cm. long; 0'4 — 0'6 cm. in diam.; leaves 
usually erect-incurved, more rarely ascending or spreading ; connate 
at the base, turgidly 3quetrous, gradually widened towards the oblique 
or rounded apex, minutely punctulate, exceeding the internodes, 
1-5— 2-5 cm. long, 0'8— 09 cm. diam.; flowers terminal, solitary 
pedunculate, the peduncles bi-bracteolate in the middle, 1 2 cm. 
long, omerous, 1'5 — 2 cm. diam.; sepals equal in length, oblong- 
lanceolate obtuse, 08 — 1 cm. long; petals (staminodes) golden yellow, 
longer than the sepals; stamens in several series; glands contiguous 
semi-lunate ; styles erect linear-filiform, setaceously acuminate, 0 7
