556 CXXII. EUPHORBIACEH (BROWN), [ Zuphorbia. 
103. E. media, V.#. Br. A tree up to 20 ft. high when growing 
singly, or forming bushes when grown for fences, etc., apparently uni- 
sexual, only male specimens seen. Branchlets terete, articulated to the 
branches, leafless except when very young, alternate or clustered, 1-2} 
lin. thick. Leaves soon deciduous, sessile, 2—5 lin. long, 4 lin. broad, 
linear, acute or subobtuse, with a few very minute crisped hairs, chiefly 
on the under surface. Involucres in dense head-like subsessile terminal 
clusters 44} in. in diam., cup-shaped, 14-14 lin. in diam., puberulous with 
minute crisped hairs outside, with 5 glands and 5 small ovate to sub- 
quadrate ciliate lobes; glands distant, peltate, }-} lin. in diam., elliptic 
or suborbicular. Ovary and capsule not seen.—Z. Tirucalli, T. Thoms:

Var. Bagshawei, N. E. Br. Involucres larger, about 2 lin. in diam. and fewer m 
a cluster than in the type; glands 2 to 1 lin, in diam., sometimes contiguous. Ovary 
subglobose, with 3 convex faces alternating with 3 slender ribs, puberulous with 
crisped hairs and having a very small 3-lobed calyx at its base, far exserted from the 
involucre on a rather stout erect or slightly curved pedicel 14-3} lin. long; a 
2-§ lin. long, stout, united for about 4 their length, recurved-spreading, 2-lobed ’ 
the apex. Capsule about 3 lin. in diam., thinly puberulous with very fine ee 
hairs. Seeds subglobose, about 13 lin. in diam., smooth, at first white, finally dar 
brown, with a small yellow caruncle.

The variety seems only to differ from the type in having 
involueres, with larger glands, the stems and leaves are identical ; 
type is, however, at present unknown, and when found may possibly prov 
be distinct species.
