121. E. schizacantha, Pax in Ann. Istlt. Bot. Roma, vi. 187. 

 Succulent, leafless and spiny, up to 4 ft. high. Main stem fleshy 

 li-2 in. thick, densely covered throughout with ascending-spreading 

 branches 2-3^ in. long and \-\ in, thick when dried, somewhat 4 -angled, 

 from opposite pairs of prominent teeth 1-1 ^ lin. long, each with a solitary 

 spine 8-10 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 Engl. Jahrb. xxxiv. 80.

Closely allieil to JE. glocliidiata, but the peculiar habit and longer spines with 

 straig'lit (not recurved) forks readily dislinfruish it. With age the surface of the 

 spines decomposes so as to make them sometimes appear to be pubescent. 



122. E. glochidiata, Pay in Aim. Istit. Bot. Poma, vi. 187. A 

 succulent branching leafless spiny shrub IJ-o ft. high, glabrous. 

 Branchlets slender, about \ in. thick in the dried specimens, ascending 

 or spreading, 4-angIed, 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, |— J in. apart, horizontally 

 spreading, '2l-\ lin. long, with the forks shorter than the shaft, widely 

 diverging-recurved and with a pair of diverging-ascending prickles 

 J-1 lin. long at the base, brown or grey, on a 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, '2\-d lin. in diam., very shallowly cup- 

 shaped or almost saucer-shaped when fully developed, glabrous, 

 apparently red or purplish, with a spreading slightly a-notciied con- 

 tinuous rim-like gland or margin surrounding f) 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. 71).

In all structural characters this jdant is a Synadeniiim and only differs from that 

 genus in its habit. 



123. E. furcata, A". K. Br. A succulent leafless spiny perennial. 

 Branches when diied ubout 2 lin. in diam., a])parently 4-angled, glabrous; 

 angles compressec^, produced into deltoid-subulate or spine-like horny- 

 margined tubercles 2-5 lin. long and i-| in. apart, forked into 2 small 

 spines h-\ lin. long at the apex and bearing a pair of slender dark 

 brown spines 1-1 i lin. long at the base, with the dark brown horny 

 margin of the tubercles decurrent to about half-way to the tubercle 

 below. Cymes arising from the axils of the small pair of spines, solitary 

 or 2 together, pedunculate, bearing o involucres, glabrous ; peduncles 

 2-3 lin. long, with the 2 lateral branches IJ lin. long. Bracts | lin.
