diam., cup-shaped, glabrous, with 5 glands and 5 subquadrate or trans- 

 verse fringed lobes ; glands contiguous, about | lin. in their greater 

 diam., transversely oblong, entire. Capsule J in. in diam., somewhat 

 3-lcbed, with the rounded lobes faintly keeled down the back, glabrous, 

 far exserted on a curved and twisted pedicel \-\ in. long ; styles J-1 lin.

 with large dilated or subcapitate tips. Seeds not seen mature, but 

 apparently smooth.

Clo!^ely related to E, renenijica, Trem., but the spines are not flattened at the 

 base, the leaves are different in form, more crisped on the margins and the styles 

 loiifrer, less united and more slender. 



115. E. venenifica, Trhaaux ex Kotschij in Alhj. Ueberbl. des Xil- 

 Lmider, 172. A large bush-like or arborescent spiny cactus-like 

 perennial, branching at the base into few or several main cylindric 

 stems several inches thick, which are loosely branched in an irregular 

 manner (ex IWhaavr's figure). Ultimate branchlets cylindric, 1-H in. 

 thick, with several series of spine-pointed slight tubercles, ohibrous. 

 Spines stout, \-\ in. long, much dilated or flattened at the base where 

 the hardened part ends abruptly, not extending into a suborbicular 

 horny shield, brown or greyish brown, with a large leaf scar in the axil 

 of each. Leaves deciduous, o-l(>| in. long, J-l| in. broad, narrowly 

 lanceolate, oblanceolate, cuneate or oblong-cuneate, varying from some- 

 what acuminate to subtruncate, tapering into a short stout petiole or 

 subsessile, entire or finely crisped at the margin, apparently somewhat 

 fleshy, glabrous on both sides. Cymes solitary in the axils of the 

 tubercles, J- J in. long, including the short stout compressed 2-4 lin.- 

 long peduncles, once or twice forked, with the branches 8-flowered. 

 Bracts adpressed to the involucres, submembranous, 1^-2 lin. long, 

 ovate-oblong, very obtuse, toothed at the apex and slightly on the sides, 

 glabrous. Central involucre sessile, lateral shortly pedunculate, 1 J-l| 

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

 very broadly cuneate lobes, fringed at the top; glands contiguous, 

 \-\ lin. in their greater diam., transversely oblong, entire. Ovary and 

 the deeply o-lobed capsule erect, the latter 8 J lin. in diam. finally 

 exserted on a pedicel up to j in. long, glabrous; styles about | lin. 

 long, united into a short stout cone at the lower half, with the stout 

 tips recurved-spreading, entire at the dilated apex. Seeds globose, 

 about 1 J lin. in diam., smooth to the eye, but covered with an excessively 

 minute lace-like fibrous reticulation. — Boiss. in DC. Prodr. xv. ii. 178 ;
