flowers from whitish to yellowish,.about ^ in. in diameter when fully- 

 expanded ; sepals 5, ovate, obtuse, about t^}-^ 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, yg- in. high, with short vague 

 lobes or nearly entire ; the inner whoi-1 of the corona consisting 

 of 5 triangular lobes inserted on the androecium 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, 2f to S^ in. 

 long, nearly glabrous and smooth, spreading or pendulous ; seeds 

 compressed, ovate or oblong-ovate, i in. long, rounded at the base, 

 truncate at the apex where it has a silky whitish very pallid tawn} 

 spreading coma about an inch long. 



HuiLLA. — In rocky thickets at the base of Morro de LopoUo ; fl. and 

 fr. Dec. 1859 and Jan. to March 1860. No. 4261. 



This species should be compared with iS. hrachystigma Hook. Ic. PI. 

 t. 861 (1^52) = 8. Stochsh Hook. f. Fl. 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 Sarcostenima 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 4| ft. high, dichotomously 

 branched from the base, csespitose 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 5^ 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 21 in. long, i to t in. broad, f to I in. thick ; 

 the seeds are i in. long with a brittle coma. Coll. Carp. 732. 



This is the Sarcnstem ma referred toin Journ. Linn. Soc. v. p. 185 (1861).
