 ^.80. A stout succulent, 3-4 ft. high, with several branches. Main 

 stem up to G in. thick ; branches 2-4 in. thick, naked or leafy at the 

 apex only, cylindric, with crowded spirals of slightly prominent diamond- 

 shaped tubercles J-| in. in diam., each marked with a large leaf-scar

 deciduous with age. Leaves 8-15 in a terminal tuft, recurved-spreading, 

 8-12 in. long, i-| in. broad, strap-shaped or broadly linear, obtuse to 

 •emarginate, apiculate, narrowed to a sessile base, green. Cymes arising 

 from the axils of the leaves, on peduncles 4-5 lin. long, bearing 3 in- 

 volucres, with the lateral on branches 2-l\ lin. long, glabrous. J3racts

114. E. unispina, ^V. F. Br. A stout succulent bush, up to 

 10 ft. high, leafy at the tips of the branches, naked below% or perhaps 

 sometimes entirely leafless, spiny. Branches J-1 in. (or perhaps more) 

 thick, cylindric, with several spiral series of solitary dark grey spines 

 J-i in. long, stout, not much flattened at the base, but very abruptly 

 dilated into convex suborbicular horny light grey shields \-\ in. in 

 diam., absent from some parts, glabrous. Leaves few in a tuft at the 

 tips of the branches, 2-4J in. long, J-1 in. broad at the apex, cuneate 

 or linear-cuneate, broadly rounded to rather deeply 2-lobed at the more 

 or less dilated apex, thence gradually tapering to the sessile base, with 

 a short point in the notch and the margin narrowly crisped and frilled 

 all round or entire, fleshy, glabrous on both sides. Cymes small, arising 

 from the axils of the leaf-scars or spine-shields, about J in. or less in 

 diam., subsessile, bearing 3-9 involucres, glabrous. Bracts adpressed 

 to the involucres, membranous, about 1 lin. long and as much or more 

 in breadth, suborbicular-ovate, very obtuse, minutely denticulate. 

 Central involucres sessile, lateral very shortly pedunculate, \ in. in
