^yes at the apex of the branches close to the spine-shields, lower 

 down at 2-3 lin. above them. Cymes sessile, with 3 involucres, 2 of 

 them on lateral peduncle-like branches h-l Hn. long. Bracts small, 

 membranous, oblong, acute or toothed at the apex. Involucre 1 1-1| lin. 

 in diam., cup-shaped, with a rim-like mark around the middle when 

 hermaphrodite, glabrous, with 5 glands and ') quadrate fringed lobes ; 

 glands |— 1 lin. in their greater diam.. transversely linear-oblong, erect 

 and closely contiguous in fruit, probably spreading in flower. Capsule 

 immature, 1§ lin. in diam., glabrous, with a slight rim-like calyx at its 

 base, erect on a pedicel shorter than the involucre; styles § lin. long, 

 united at the base, then recurved and curled like a cork-screw, blender, 

 thickened at the apex.

131. E. brevis, X. E. Br. Perennial, succulent, leafless, spiny, 

 llootstock a tuber, sometimes several inches in diam. Stems numerous, 

 erect, 2-3 in.; high, slender, 2-2J lin. in diam., 3-angled, glabrous, 

 yellowish-green ; angles acute, more or less sinuate-toothed. Leaves very 

 rudimentary, scale-like, about J lin. long and \ lin. broad, broadly 

 deltoid. Spines 1-2 lin. long, in pairs 4-G lin. apart, widely diverging 

 and dilated at the base so as to form horny shields not longer than 

 their breadth at the base, and bearing on the upper margin a semi- 

 circular leaf-scar. Flowering-eyes in the axil of and closely contiguous 

 to the spine-shields. Cymes with peduncles 3-5 lin. long, at first with 

 1 sessile male involucre, ultimately developing into a simple 2-branched 

 cyme, with fertile involucres on branches \-\ in. long, glabrous. Ik-acts 

 §-lJ lin. long, with the lower rounded and the upper obovate, very 

 obtuse or rounded at the apex, apiculate, denticulate. Involucres when 

 fully developed and fertile about 2 lin. in diam. (developed males not 

 seen), cup-shaped, glabrous, yellowish, with T) glands and 5 ratliei' large 

 erect transversely oblong fringe-toothed lobes ; glands contiguou>, about 

 1 lin. in their greater diam., transversely oblong, entire, minutely 

 granulate on the upper surface. Ovary acutely 3-angled, glabrous, w^ith 

 a rudimentary rim-like calyx at its base, exserted on a moderately stout 

 recurved pedicel about \ in. long; styles | lin. long, very shortly united 

 at the base, spreading, bifid at the apex. Capsule and seeds not seen.

 the semicircular leaf-scar, which sometimes has a minute prickle (stipule) 

 on each side of it) not longer than broad. Flowering-eyes in the axils 

 of and close to the spine-shields. Cymes subsessile, at first consisting of 

 a solitary involucre, ultimately of three. Bracts about | lin. long, \ lin.
