recurved pedicel twice as long as the involucre ; styles united intoa very 
short cone at the base, those of the submonecious plant } lin. long, 
rather stout and bifid at the tips, of the female plant 1 lin. long, rather 
slender, capitate and minutely bilobed at the apex. Capsule and seeds 
not seen. 
North Central. Dar Banda, Chevalier, 6699! 6752! 7162! 
Very nearly allied to H. venenifica and E. unispina, differing from the former by 
its narrower leaves, longer and rather more slender spines and peduncles and 
different styles, and from E. unispina by its spines being deciduous and not dilated 
into a persistent horny shield at the base. 
152a, Euphorbia strangulata, V./. Br, A succulent spiny leaf- 
less bush, branching at the base. Stems or “branches spreading- 
ascending, up to 3 ft. high” (Gossweiler), 1-1} ft. long in the specimens 
seen, deeply constricted into numerous orbicular-ovate or shortly conic- 
ovate segments 1-24 (mostly 1}) in. long, 14-2 in. in diam., 5-angled, 
light green, apparently not glaucous; angles wing-like, 3-2 in. broad, 
3 in. thick, slightly sinuate-toothed, with continuous horny margins. 
Leaves rudimentary, scale-like, about 3 lin. long and broad, broadly 
deltoid-ovate, reddish-brown, soon deciduous. Spines 14-3} lin. long, 
diverging, in pairs }-} in. apart, with or without very minute or rudi- 
mentary prickles at their base, at first (together with the horny margin 
of the stem-angles) brown, becoming grey. F lowering-eyes 2 lin, above 
the spine-pairs, each producing a sessile cyme of 3 sessile involucres. 
Bracts 1-1} lin. long, rounded, concave, submembranous. Involucres 
24 lin. in diam., cup-shaped, glabrous, with 5 glands and 5 rather short 
transversely oblong fringed lobes; glands 11g lin. in their greater 
diam., rather narrowly transversely oblong, slightly concave or when 
dried appearing slightly 2-lipped, entire ; central involucre male, lateral 
hermaphrodite ; ovary sessile, included, rather sharply 3-angled, glab- 
rous; styles partly exserted, 1 lin, long, united for a third of their 
length, with spreading bifid tips. 
Lower Guinea. Angola: onthe rocksof Pungo Andongo, Gossweiler ! 
Described from a living branch and some dried material sent to Kew by Mr. 
J. Gossweiler. Apparently allied to Z. bellica, Hiern, but the stems are 5-angled, not 
glaucous and the spines are much shorter than in that species. 
190a. Euphorbia ambacensis, V./#. Br. A succulent leafless 
spiny bush, growing to “ 12 ft. high, branching at the base 3 stems single 
or numerous, strictly erect ; branches parallel to the stems” (Gossweiler), 
3-~4-angled in the specimen seen, 2-3 (or more?) in. in diam., cone ned
