The type of E. monocephala consists of leafless branches, with solitary involucres, 

 the lateral involucres being undcveloi)ed and having shorter and more entire segments 

 to their glands than in E. Scheffleri, but all the species with pectinately cut glands- 

 vary in this character, and it is quite evident that E. monocephala and E. Schfffierl 

 are not specifically distinct. The pubescence on the leaves is very variable. 



91 . E. somalensiSy Vax In Ann. Tstit. Bot. Roma, vi. 187. A shrub, 

 without spines, leafless at the time of flowering (always?). Branchlets 

 ]-2 lin. thick, terete, woody or perhaps slightly fleshy when young, at 

 first minutely puberulous, becoming glabrous, brown. Umbel terminal, 

 of few rays, each 2-3 lin. long and bearing 1 involucre, very minutely 

 puberulous. Involucre about \ in. in diam., broadly cup-shaped, 

 minutely puberulous, with 5 glands and 5 subentire or obscurely toothed 

 broad lobes; glands about 1^ lin. long and l|-2 lin. broad, somewhat 

 elliptic or suborbicular, with 3-5 filiform tinger-like processes on the 

 outer margin, thickened and slightly bifid at the apex. Ovary included 

 in the involucre, glabrous, with a very rudimentary rim- like calyx at 

 its base; styles li lin. long, very shortly united at the base, slightly 

 thickened and minutely 2-lobed or notched at the apex. Fruit and 

 seeds not seen.

I have not seen the type of this species, but describe from Riva's, 333, which is 

 named E. somalensis by Dr. Pnx, and except in tlie minute pubescence (which might 

 easily be overlooked) agrees with his description of that species. 



92. E. noxia, Pax in Engl. Jahrh. xix. 124, t. 2. A shrub about 

 10 ft. high, sparingly branched, glabrous. Branches stout, 4-5 lin. 

 thick, apparently somewhat fleshy when young, becoming woody, leafy 

 only at the tips, naked and marked with closely placed leaf-scars below, 

 brown. Leaves alternate, rather crowded in terminal rosettes or with 

 some scattered for a short distance along the young branches below the 

 rosettes, 2^-0 in. long, |-lj in. broad, cuneately oblanceolate, obtuse 

 and apiculate or mucronate, tapering to the sessile base, glabrous on 

 both sides. Umbel terminal, 4- (or perhaps 5-) rayed; rays 1;^ in. 

 long, probably ultimately forked, in the type specimen each with a pair 

 of bracts, 1 shortly pedunculate involucre and a pair of undeveloped 

 cyme-branches at its base, glabrous. Bracts about 1 in. long and f-J 

 in. broad, broadly ovate, acute, tipped with a subulate point l|-2 lin. 

 long, cordate at the sessile base, glabrous. Involucre |-| in. in diam., 

 cup-shaped, velvety-puberulous, with 4 glands and 5 subquadrate fringed 

 lobes; glands about \ in. long and as much in breadth, shortly stalked, 

 somewhat fan-shaped, with the outer margin cut into 0-1 filiform 

 segments thickened at their tips. Ovary densely pubescent, without
