690 LXXXIII, ASCLEPIADE. [| Sarcostemma 
flowers from whitish to yellowish, about } in, in diameter when fully 
expanded ; sepals 5, ovate, obtuse, about ;1, in. long, somewhat 
pubescent at the back near the base; corolla 5-partite, the 
segments } in. long by } in. broad, oval, rounded at the apex, 
glabrous or minutely glandular ; corona double; the outer whorl 
hemispherical, } in, in diameter, ;'; in. high, with short vague 
lobes or nearly entire; the inner whorl of the corona consisting 
of 5 triangular lobes inserted on the andreecium at about the level 
of the top of the outer corona, ,\, in. long, extending about as 
high as the anther-appendages, rather exceeding the shortly 
apiculate stigma ; follicles narrowly lanceolate-conical, 24 to 3? in. 
long, nearly glabrous and smooth, spreading or pendulous ; seeds 
compressed, ovate or oblong-ovate, } in. long, rounded at the base, 
truncate at the apex where it has a silky whitish very pallid tawny 
spreading coma about an inch long. 
Huitia.—In rocky thickets at the base of Morro de Lopollo ; fl. and 
fr. Dec. 1859 and Jan. to March 1860. No. 4261. 
This species should be compared with S. brachystigma Hook. Ic. Pl. 
t. 861 (1852) = S. Stocksii Hook. f. FJ. Brit. Ind. iv. p. 27 (1883), 
which it resembles in the characters of the corona and stigma; it 
differs, however, in the smaller number of the rather larger flowers in 
each umbel. It is probably the same species as the Sarcostemma col- 
lected by G. Don at Sierra Leone and mentioned by Bentham in Hook. 
Niger Fl. p. 454 (1849) as difficult to distinguish from S. brevistigma 
Wight & Arn. 
The next following No. perhaps belongs here :— 
MossaMEDES.—Frutescent, 3 or rarely 4 to 44 ft. high, dichotomously 
branched from the base, cespitose in clumps of 3 to 4 ft. in diameter ; 
stems and branches cylindrical, dichotomous, jointed, covered with a 
farinaceous glaucous deciduous bloom, sheathed at the nodes with a 
gold-coloured band or ring ; follicles linear-lanceolate, nearly smooth, 
erect or at length (after the release of the seeds and placenta) pendu- 
lous, always terminal on the branches or branchlets, 5 to 53 in. long. 
On dry slopes, in other respects quite barren, of Serra de Montes 
Negros, near Mossamedes, at a distance of 6 miles from the coast 
towards the east, very abundant ; with dehisced fruit 10 Aug. 1859. 
No. 4260. 
The following should also be compared with this species, but the 
fruit is shorter and thicker :— 
MossaMEDES.— A leafless, suberect shrub ; the numerous stems and 
branches virgate, glaucescent ; flowers whitish-yellowish. In rocky 
places near the citadel of Mossamedes ; fr. June 1863. The spindle- 
shaped follicles measure 2 to 24 in. long, 4 to } in. broad, ¢ to } in. thick; 
the seeds are } in. long with a brittle coma. CoLL. Carp. 732.
