Easily recognised by the dome-like uhite-woolly mass of bracteoles filling the 

 involucre. 



00. E. Cameronii, N. E. Br. Probably a shrub, only 2 branchlets 

 seen, about 5 in. long and lJ-2 lin. thick, terete, naked, marked with 

 small alternate crescent-shaped leaf-scars, probably succulent when 

 young, glabrous. Leaves not seen. Inflorescence apparently terminal, 

 but only 3 detached involucres seen, embraced by their bracts and on 

 peduncles 1 lin. long. Bracts large, white, very conspicuous, widely 

 spreading, J-g in. long, J in. broad, sessile, orbicular-ovate, folded 

 together and slightly recurved at the acute or apiculate apex, glabrous. 

 Involucre solitary, sessile, 2J lin. in diam., cup-shaped, glabrous, with 

 5 glands and 5 erect transversely oblong fringed lobes; glands l-lj 

 lin. in their greater diam., transversely oblong, very distinctly ^-lipped, 

 with the inner lip about half as large as the outer. Ovary (not seen 

 mature) with :> convex faces and o slender ribs between them, glabrous, 

 with a small cupular entire calyx at the base ; styles 1 lin. long, united 

 nearly to the top, with very short stout arms, minutely lobed at the 

 apex. Fruit and seeds not seen.

This apiiears to be a very showy plant when in flower, and would be well worth 

 cultivating. The involucral bracts are as large as or larger than those of E. splendens, 

 Bo]'., and quite as conspicuous, but are white instead of bright red. 



100. E. nubica, K. E. Br. A succulent bush up to 6 ft. high, 

 leafless except on the very young branches, spineless, glabrous. Branchlets 

 alternate, more or less clustered, subparallel or very little divergent, 

 2J-12 in. long, 1^-3 lin. thick, terete, with prominent leaf -scars. 

 Leaves not seen, soon deciduous. Umbels terminal, of 3-7 simple rays, 

 -l-J in. long, each bearing 1 involucre, glabrous ; when young with a 

 whorl of thin green oblong acute bracts at the base of tlie umbel about 

 as long as the peduncle-like rays and a pair under each involucre about 

 2 lin. long and 1^-2 hn. broad, orbicular-obovate, obtuse, apiculate, all 

 soon deciduous. Involucre J in. in diam., broadly and shallowly cup- 

 shaped, glabrous, with 4 glands and 5 transverse scarcely toothed or 

 ciliate but sometimes 2-lobed lobes; glands 1-1 J lin. in their greater 

 diam., transversely elliptic or suborbicular. Capsule about J in. in 

 diam., obtusely 3-angled, far exserted on a pedicel ultimately J in. or 

 more long, glabrous; styles 1 lin. long, shortly united at the base, then 

 spreading, bitid at the apex with the lobes widely diverging. Seeds 

 about 1| lin. long, ellipsoid, with a small caruncle, faintly tuberculate- 

 rugulose, whitish. — E. Schimperi, Schweinf. in Bull. Herb. Boiss. vii.
