Plant apparently two feet high; 



the 



slender stems and branches entirely woody below, glabrous, cxccpt the minute hairs 

 in the axils. Leavcs 6 to 12 lincs long, scarccly a line wide, probably nearl)

Cyme few-flowcrcd 



the branchcs short, anglcd, articulatcd 



Flowers closely sessile in the forks, disarticulating and readily falling away in the 



Sepals thin, very obtuse, sevcral-nerved, with narrow scarious 



dried specimens 



margms. Petals not unguiculatc, in anthesis longer than thc caly 



Filaments 



ntly all somewhat connate at the base, and further adnate, usually in fours, to the 



base of each petal 



Anthers of two oblong and discrete cells, without any conncc-

fluent after anthesis. The free central placenta reaches quite to the narrowed apex 

 of the cell, but is very slendcr, and not ovuliferous towards the summit : bclow the 

 middle it is crowded with ovules, in shape like those of Portulaca olcracea. Capsule 

 nearly half an inch long, covered, exccpt thc tapering summit, by the persistcnt, 

 and, in thc dried state, at length subscarious calyx, onc-ccUcd, thrcc-valved from the 



apex : valves rather 



each of the three valves of which splits 



parating from a thiii and white papcry endo 



and the sutural ncrves also m- 

 cline to separate. Seeds crowded on the central placenta, uncinate or arcuate; the 

 granulated testa rather loose and soft, but conformed to the thin internal integu- 

 ment, which is exactly conformed to the uncinate-arcuate, slender cmbryo ; the albu- 

 men being reduced to a mcre vestige, or to a few loose starch-grains, within the 

 curvature. Radicle straight, when the seed is uncinate, or a Httle curvcd ; the coty- 

 ledons incumbcntly incurved, as in Talinum tcrctifolium, &c., but sometimes,^if I 

 mistake not, accumbent. 



A genus closely allied to Anacampscros of South Afj 



from which 



ajad Grahamia, Gillies, of Chili, with much the habit of the 

 distinguished by the ebracteate flowers, thc dissilicnt endocarp, and the wingless 

 seeds.* From Anacampseros it difFers in habit, in the persistent equal sepals, the 

 short style, the coriaceous valves of the capsule, which do not separate from the base 



and fall away, &c.
