recurved pedicel twice as longas theinvolucte ; styles united into a vory 

 short cone at the base, those of the submon(ecious plant | lin. lon«', 

 rather stout and bifid at the tips, of the female plant 1 lin. long, rather 

 slender, capitate and minutely bilobed at the apex. (Japsule and seeds 

 not seen. 



xrorth Central. Dar liaiula, C/zecaZte;-, 6699 ! 6752! 71621 

 Very nearly allied to E. venenifica and E. tinispina, differing from the former by 

 its narrower leaves, longer and rather more slender spines and i)eduncles and 

 different styles, and from E. nnispina by its si)inos Ijeinf^ deciduous and not dilated 

 into a persistent horny shield at the base. 



152a. Euphorbia strangulata, y.L\ Br. A succulent spiny leaf- 

 less bush, branching at the base. Stems or " branches spreading- 

 ascending, up to 8 ft. high " (Gossiveiler), 1-1^ ft. long in tlie specimens 

 seen, deeply constricted into numerous orbicular-ovate or sliortly conic- 

 ovate segments 1-2J (mostly 1|) in. long, 1^-2 in. in diam., :>-angled, 

 light green, apparently not glaucous; angles wing-like, f-J in. broad, 

 J in. thick, slightly sinuate-toothed, with continuous horny margins. 

 Leaves rudimentary, scale-like, about | lin. long and broad, broadly 

 deltoid-ovate, reddish-brown, soon deciduous. Spines l!!,-:5.l lin. long, 

 diverging, in pairs J-J in. apart, with or without very minute oi- rudi- 

 mentary prickles at their base, at first (together with the horny margin 

 of the stem-angles) brown, becoming grey. Flowering-eyes 2 lin. above 

 the spine-pairs, each producing a sessile cyme of 3 sessile involucres. 

 Bracts 1-1 J lin. long, rounded, concave, submembranous. Involucres 

 2 J lin. in diam., cup-shaped, glabrous, with 5 glands and ") rather short 

 transversely oblong fringed lobes ; glands 1-1 J 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.

Described from a living branch and some dried material sent to Kew by Mi. 

 J. Gossweiler. Apparently allied to E. bellica, Hiern, but the stems are 5-angled, not 

 glaucous and the spines are much shorter than in that species. 



IdOa. Euphorbia ambacensiSy N.E. Br. A succulent leafless 

 spiny bush, growing to " 12 ft. high, branching at the base ; stems single 

 or numerous, strictly erect ; branches parallel to the stems " (Gossiceiler), 

 3-4-angled in the specimen seen, 2-3 (or more?) in. in diam., constricted 

 into subelliptic to more or less conical segments 2-{) (or more ^ in. long, 

 grass-green, perhaps slightly glaucous on the younger parts; angles 

 1 J-2 lin. thick, slightly sinuate-toothed ; spine-shields not connected by 

 a horny border, suborbicular and 2 lin. in diam., orobovate and 2^-3 lin. 

 long and 2-2J lin. broad ; spines 1-3 lin. long, in pairs J-5 in. apart, 

 diverging, with deciduous hardened auricles (stipules) at their basewlien
