#80. A stout succulent, 3-4 ft. high, with several branches. Main 
stem up to 6 in. thick; branches 2-4 in. thick, naked or leafy at the 
apex only, cylindric, with crowded spirals of slightly prominent diamond- 
shaped tubercles 3—? in. in diam., each marked with a large leaf-scar 
and bearing a single flattened deflexed brown spine }—4 in. long, 
deciduous with age. Leaves 8-15 in aterminal tuft, recurved-spreading, 
8-12 in. long, 3-3 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 2-24 lin. long, glabrous. Bracts 
13-23 lin. long, elliptic, keeled. Involucre subeampanulate, with trans- 
versely elliptic glands } lin. in their greater diam. Ovary scarcely 
exserted ; styles about 4 lin. long, spreading, slightly thickened at the

lid. E. unispina, V. #. 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 }~1 in. (or perhaps more) 
thick, cylindric, with several spiral series of solitary dark grey spines 
~2 in. long, stout, not much flattened at the base, but very abruptly 
dilated into convex suborbicular horny light grey shields 4-} in. in 
diam., absent: from some parts, glabrous. Leaves few in a tuft at the 
Ups of the branches, 2-41 in. long, $-1 in. broad at the apex, cuneate 
Dis linear-cuneate, broadly rounded to rather deeply 2-lobed at the more 
or less dilated apex, thence gradually tapering to the sessile base, with 
4 short point in the notch and the margin narrowly crisped and frilled 
round or entire, fleshy, glabrous on both sides. Cymes small, arising 
rom the axils of the leaf-scars or spine-shields, about 3 in. or less in 
‘am., subsessile, bearing 3-9 involucres, glabrous. Bracts adpressed 
to the ivolucres, membranous, about 1 lin. long’and as much or more 
re breadth, suborbicular-ovate, very obtuse, minutely denticulate.
