Euphorb. 16, t. 44. A woody shrub, with annual herbaceous flowering 
branches 6-12 in. (or more 2) long, which partly or entirely decay, divided 
at the top into a cyme or umbel of 3 branches, ?—10 in. long, which are 
1-3 times trichotomously or dichotomously divided, sometimes also with 
lateral simple flowering branches below the umbel, glabrous or slightly 
puberulous on the upper parts. Leaves alternate, with a whorl of 3

obtuse, apiculate, broadly and acutely cuneate at the base, minutely 
toothed, glabrous on both sides or slightly puberulous on the midrib 
beneath. Stipules none or represented by minute glands. Umbel 
terminal of 3 primary trichotomously or dichotomously divided rays 
1-10 in, long, glabrous. Involucres in small cymes of 3 at the ends of 
the umbel-branches, subsessile between a pair of reduced leaves, cam- 
panulate, about 1 lin. in diam., minutely puberulous outside, with 4 
glands and 5 short transverse or subquadrate fringed lobes ; glands 
:-} lin. in their greater diam., transversely oblong, entire. Ovary with 
a small cupular slightly 3-lobed perianth at its base ; styles }-3 lin. long, 
shortly united at the base, straight and collected, not spreading, minutely 
bifid at the apex. Capsule 2 lin. long, 13 lin. in diam., shortly oblong, 
thinly and minutely puberulous. Seeds 1} lin. Jong, rectangular,
