pocket -like cavity at the base, rather thin in texture, white-pubcrulous 

 on the inner face and back, ciliate. Capsule IJ lin. in diam., with a 

 distinct circular rim-like calyx at its base, puberulous, exserted on a 

 rather stout pedicel about twice as long as the involucre ; styles J lin. 

 long, shortly united at the base, minutely bifid at the apex. Seeds 

 nearly 1 lin. long, 4-angularly pyramidal, truncate at the base, with 2 

 large pits on each face, giving the appearance of a double constriction, 

 and abruptly constricted into the acute apex, glabrous, dark brown.

E. vapoichs only differs from the Arabian E. liadramaidicn, liaker (syn. 

 E. ohlonijicQulis, Baker), by the stem \m/\\\^ distinctly tuberculato and the pedicel of 

 the ovary rather longer and more slender than in tliat species, otherwise it is quite 

 the same. 



111. E. rubella, Pax in Emjl. Jahrh. xxxiii. 287. Stem probably 

 solitary, erect, \\ in. high in the type, nearly J in. thick, probably 

 stouter when 'alive, cylindric, fleshy, slightly tuberculate when dried, 

 bearing a crown ot 5 or G leaves at the apex, glabrous. Leaves erectly 

 spreading, 8-11 lin. long, including the 1J--2 lin. -long petiole, \-\ in. 

 broad, elliptic, obtuse, apiculate, rounded to acute at the base, glabrous 

 on both sides, purple beneath and more or less sutlused with it above. 

 Peduncles arising from the apex of the stem outside the tuft of leaves, 

 T^-f in. long, slender, bearing a small cyme of 1 sessile and 2 shortly 

 pedunculate involucres at its apex, glabrous. Bracts 1^-2 lin. long, 

 broadly obovate, abruptly cuspidate-apiculate at the obtuse apex, thin 

 and veiny. Involucres £-1 lin. in diam., cup-shaped, glabrous, with 4 

 glands and T) subquadrate lobes cut into 3-4 long teeth at the apex; 

 gland> about \ lin. in their greater diam., transverse, narrowly oblong, 

 peltate, with a depressed centre, entire. Ovary exserted and finally re- 

 curved on a pedicel 1^ lin. k ng, glabrous ; styles \ lin. long, free to the 

 base, ascending, deeply bifid at the apex, with thickened or capitate 

 stigmas.

 A succulent much branched bush " of grotesque appearance, 5 ft. high " 

 {Barter). Branches cylindric, li— IJ in. thick, somewhat obscurely 

 areolate, scarcely tuberculate when alive, but apparently so when dried, 

 glabrous, greyish, naked or bearing 5-6 deciduous leaves at the apex of 

 the branches, spineless. Leaves spreading, 2^-5^ in. long, 1|-2J in. 

 broad, cuneately obovate, rather deeply notched or shortly 2-lobed at 

 the apex, with the lobes broadly rounded and a minute apiculus in the 

 notch, tapering below into a very short stout petiole, thick and fleshy, 

 glabrous, green. Inflorescence at first consisting of a single involucre, 

 ultimately developing into a small cyme J-f in. in diam. in dried speci-
