axillary ; male generally slightly exceeding the petiole, 14-1} in. long, 
with a short peduncle and a few spreading branches, bearing the 
shortly stalked flowers in small clusters ; bud 1 lin. in diam. ; perianth 
4-partite, segments bearing dorsally a few short stinging hairs. 
Female inflorescence ultimately longer than the male, up to 2 in. long, 
somewhat laxly paniculate ; flowers in small sessile clusters protected 
by tufts of short slender stinging hairs ;_perianth shallowly 4-lobed 
with ciliolate margin, enveloping the spheroidal young ovary, the 
large transversely ellipsoidal mass of short ferruginous stigmatic 
hairs alone projecting ; with development the ovary becomes ovoid 
and somewhat compressed; when about 1 lin. long the upper 
third projects from the shallowly lobed perianth, bearing the stigma 
at the oblique tip. Fruit compressed-ovoid, enveloped except at 
the extreme apex by the succulent perianth forming a broadly ellip- 
soidal drupe-like structure a little over 1 lin. long.—Durand & Schinz,

Specimens collected by Swynnerton (nos. 1518! and 1518a!) in very young 
male flower in the Chirinda Forest and referred by S. Moore to U. obovata, Benth. 
(in Journ. Linn. Soc. xl. 206), are probably referable to U. cameroonensis. 
The South African U. Woodii, N.E. Br., is very closely allied ; the specimen 
from Angola (Welwitsch, 6294 !) has the shorter proportionately broader leaves 
of the South African plant. 
Var. Laurentii, Rendle. Distinguished from the species by the cuneate base 
of the leaf drawn out into a blunt acumen.—U. Laurentii, De Wild. Miss. E.

numerous adventitious roots) ; branches glabrous, armed with spines 
bearing stinging hairs. Leaves elliptic, long-acuminate, acute, base 
more or less acute, margin entire, 3-nerved, with 1-2 lateral nervy 
on each side, curving upwards and uniting, slightly prominent, 23-
