The type of £. monocephala consists of leafless branches, with solitary involucres, 
the lateral involucres being undeveloped and having shorter and more entire segments 
to their glands than in HZ. Scheffleri, but all the species with pectinately cut glands 
vary in this character, and it is quite evident that EZ, monocephala and E. Schefflert 
are not specifically distinct. The pubescence on the leaves is very variable. 
91, E.somalensis, Pax in Ann. Istit. Bot. Roma, vi. 187. A shrub, 
without spines, leafless at the time of flowering (always?). Branchlets 
1-2 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 14 lin. long and 14-2 lin. broad, somewhat 
elliptic or suborbicular, with 3-5 filiform finger-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 1} 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 . 
named £. somalensis by Dr. Pax, and except in the minute pubescence (which might 
easily be overlooked) agrees with his description of that species. 
92. E. moxia, Pax in Engl. Jahrb. 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 ne 
some scattered for a short distance along the young branches below the 
rosettes, 23-6 in. long, 4-14 in. broad, cuneately oblanceolate, obtuse 
and apiculate or mucronate, tapering to the sessile base, glabrous oP 
both sides. _Umbel terminal, 4- (or perhaps 5-) rayed; rays Le 
long, probably ultimately forked, in the type specimen each with a par 
of bracts, 1 shortly pedunculate involucre and a pair of undevelop 
cyme-branches at its base, glabrous. Bracts about 1 in. long re ; 
in. broad, broadly ovate, acute, tipped with a subulate point 13-2 im 
long, cordate at the sessile base, glabrous. Involucre 3-{ in. in diam, 
cup-shaped, velvety-puberulous, with 4 glands and 5 subquadrate sa 
lobes ; glands about } in. long and as much in breadth, shortly — sat 
somewhat fan-shaped, with the outer margin cut into 9-10 ead 
segments thickened at their tips. Ovary densely pubescent, wit
