121. E. schizacantha, Pax in Ann. Istit. Bot. Roma, vi. 187, 
Succulent, leafless and spiny, up to 4 ft. high. Main stem fleshy 
13-2 in. thick, densely covered throughout with ascending-spreading 
branches 2-3} in. long and 1-1 in. thick when dried, somewhat 4-angled, 
from opposite pairs of prominent teeth 1-14 lin. long, each with a solitary 
spine 3-10 lin. long, forked at the apex, with the forks straight and 
much shorter than the shaft and a pair of recurved prickles 1-2 lin. 
long at the base, on long linear-decurrent horny shields. Flowers and 
fruit unknown.—Pax in Eng]. Jahrb. xxxiv. 80.

Closely allied to E. glochidiata, but the peculiar habit and longer spines with 
straight (not recurved) forks readily distinguish it. With age the surface of the 
spines decomposes so as to make them sometimes appear to be pubescent. 
122. E. glochidiata, Par in Ann. Istit. Bot. Roma, vi. 187. A 
succulent branching leafless spiny shrub 14-3 ft. high, glabrous. 
Branchlets slender, about } in. thick in the dried specimens, ascending 
or spreading, 4-angled, with nearly flat sides ; angles not very prominent, 
not sinuate nor distinctly toothed. Leaves not seen, probably scale- 
like. Main spines solitary, forked at the tips, }-}in. apart, horizontally 
spreading, 24-4 lin. long, with the forks shorter than the shaft, widely 
diverging-recurved and with a pair of diverging-ascending prickles 
3-1 lin. long at the base, brown or grey, ona long linear grey or brown 
shield decurrent below the spines as a horny border nearly to the group 
of spines below. Flowering-eyes touching the apex of the shields. 
Involucres 3 together, sessile, 24-3 lin. in diam., very shallowly cup- 
shaped or almost saucer-shaped when fully developed, glabrous, 
apparently red or purplish, with a spreading slightly 5-notched con- 
tinuous rim-like gland or margin surrounding 5 contiguous broad 
transversely oblong fringe-toothed lobes. Ovary (immature) glabrous, 
without a distinct calyx, seated on a short and very stout pedicel, 
probably exserted at maturity; styles 1 lin. long, shortly united at 
the base, recurved-spreading, rather slender, entire and very slightly 
thickened at the apex.—Pax in Engl. Jahrb. xxxiv. 79.
