Luphorbia.| CXXII. EUPHORBIACEE (BROWN). 549 
glabrous, leafy at the apex, naked below, brown or dark grey, Leaves 
about 5-7 in terminal rosettes, spreading, 13-81 in. long, 3-14 in. broad, 
obovate, obtuse to broadly rounded at the apex, minutely apiculate, 
tapering from above the middle to a very short petiole, glabrous on 
both sides, slightly ciliate on the margins of the petiole. Stipules none. 
Inflorescence terminal, in the centre of the rosette of leaves, apparently 
of 3-4 or perhaps more involucres on stout peduncles + in. long, pro- 
bably forming a small umbel. Involucre } in. in diam. or perhaps 
larger, cup-shaped, glabrous, with 5 glands and 5 subquadrate subentire 
lobes; glands spreading, not contiguous, 14-1} lin. in their greater 
diam., but nearly as long as broad, transversely elliptic, minutely denti- 
culate or almost entire ; ovary with a rudimentary rim-like calyx at 
its base, exserted on a very stout pedicel about as long as the involucre, 
very minutely. puberulous; styles 1 lin. long, free, spreading, with 
revolute bifid tips. Fruit not seen.

Ellenbeck, 1163, also quoted by Pax as belonging to this species, is Z. Scheffleri, 
Pax. It differs from E. Grosseri in having pubescent leaves, different involucre- 
glands and a very large cup-shaped calyx partly enclosing the ovary. 
90. E. Scheffleri, Pax in Engl. Jahrb. xliii. 88. A branching 
shrub or small tree? Ultimate branches opposite or whorled, 4—} in. 
thick, woody, with apparently a somewhat fleshy bark, terete, glabrous, 
marked with alternate scattered leaf-scars, brown, apparently often 
leafless at the time of flowering. Leaves in the specimens seen all 
collected in terminal tufts of 5-6, spreading ; petiole 14-8 lin. long ; 
blade 14-4 in. long, 3-2} in. broad, obovate, elliptic or suborbicular, 
rounded or emarginate to subacute at the apex, apiculate, cuneately 
tapering into the petiole, varying from glabrous to thinly or densely 
pubescent on both sides, or becoming more or less glabrous above. 
Stipules none. Inflorescence terminal, at first consisting of a single 
volucre, subsessile or on a very short peduncle, from under which 
usually develop 1-3 others on glabrous peduncles 5-7 lin. long, forming 
@ small umbel when fully developed. Bracts under the involucres 
3~4 lin. long, 4-54 lin. broad, scale-like, broadly and somewhat rhomboid- 
obovoid, with slight rounded angles at the sides, entire or notched at 
the rounded top, apiculate, glabrous, densely ciliate. Involucre 6-8 
lin. in diam., broadly cup-shaped, glabrous outside and within, with 
» glands and 5 transversely rectangular fringed lobes, glands 23-3 lin. 
ong, and 3-4 lin. broad, transversely oblong or somewhat half-circular, 
ringed along the outer margin with 7-15 linear-filiform segments 3-1 
lin, long, entire or bifid at the apex. Ovary glabrous, partly or quite 
enclosed in a deep cup-shaped or short tubular glabrous calyx, more or 
less toothed at the top; styles 2 lin. long, shortly united at the base, 
very Spreading, rather stout, shortly bifid at the apex. Capsule about 
lin. in diam., acutely 3-lobed as seen from the top, with woody cell- 
walls lin. thick. Seeds } in. long, } in. broad, compressed, elliptic, 
slightly oblique, with acute margins, smooth, light brown.—Z. mono-
