Closely related to E, venenifica, Trém., but the spines are not flattened at the- 
base, the leaves are different in form, more crisped on the margins and the styles 
longer, less united and more slender. 
115. E. venenifica, 7rémaux ex Kotschy in Allg. Ueberbl. des Nil- 
Linder, 172. A large bush-like or arborescent spiny _cactus-like 
perennial, branching at the base into few or several main ¢ petit? 
stems several inches thick, which are loosely branched in an irregular 
manner (ex 7’rémaux’s figure). Ultimate branchlets cylindric, Lar fi 
thick, with several series of spine-pointed slight tubercles, glabrous. 
Spines stout, }-1 in, long, much dilated or flattened at the base where 
the hardened part ends abruptly, not extending into a suborbiat 
horny shield, brown or greyish brown, with a large leaf scar in the = 
of each. Leaves deciduous, 3-103 in. long, 4-12 in. broad, narrowly 
lanceolate, oblanceolate, cuneate or oblong-cuneate, varying from some- 
what acuminate to subtruncate, tapering into a short stout acoeese 
subsessile, entire or finely crisped at the margin, apparently hisdenys ned 
fleshy, glabrous on both sides. Cymes solitary in the axils of : 
tubercles, }-? in. long, including the short stout compressed 2-4 se 
long peduncles, once or twice forked, with the branches paece : 
Bracts adpressed to the involucres, submembranous, 1}-2 hn. io

lin. in diam., cup-shaped, glabrous, with 5 glands and 5 transvee

exserted on a pedicel up to } in. long, glabrous; styles about s ut 
long, united into a short stout cone at the lower half, with ne rade 
tips recurved-spreading, entire at the dilated apex. Seeds Stilt
