E. angularis is described as having a simple unbranched stem the height of a 
man, but the small fragment of which the type in the Berlin Herbarium consists 
seems identical with Kirk’s Lupata specimen, which is branched, 
162. E. Nyikze, Pax in Engl. Pf. Ost-Afr. C. 242. A tree up to 
45 ft. high, when young branching horizontally from the ground, when 
old with a cylindric naked trunk, surmounted by a rounded crown of 
curved ascending branches (Volkens), succulent, leafless, spiny. Branches 
3-4-angled or occasionally flat, constricted into orbicular, elliptic, ovate 
or oblong segments 2-8 in. long, 2-3 in. in diam., with the central 
solid part about 4 in. thick in young branches, thinning to almost a 
mere junction of the angles at the apex, glabrous, glaucous; angles 
wing-like, very thin, about 4 lin. thick in dried specimens and searcely 
thicker at their junction with the centre than elsewhere, more or less 
Sinuate-toothed and wavy at their margins. Leaves rudimentary, 
scale-like. Spines 1—4 lin. long, in pairs 1-3 in. apart, rather slender, 
widely diverging, grey, usually on separate narrow linear horny grey 
shields, but occasionally with the shields connected into a horny margin 
to the stem-wings. Flowering-eyes 2-3 lin. above the spine-pairs. 
Cymes with peduncles 1-2 lin. long, bearing 1 sessile central involucre 
and 2 on lateral branches 1-1} lin. long, glabrous. Bracts about 1} 
lin. long, suborbicular, entire, thin. Involucre 2}-3} lin. in diam., 
cup-shaped, glabrous, with 5 glands and 5 rectangular, oblong or sub- 
quadrate denticulate lobes; glands subcontiguous, 14-1 lin. in their 
greater diam., transversely elliptic-oblong, entire. Ovary subsessile or 
shortly pedicellate and included in the involucre, glabrous, with a 
distinct calyx at its base, having 3 acute lobes }-} lin. long; styles 
about 11 Jin, long, very shortly united at the base into a stout cone, 
then recurved-spreading, rather slender, 2-lobed or somewhat knob-like 
at the apex, Capsule exserted on a pedicel about as long as the invo- 
luere, erect, about 4 in. high and } in. in diam., truncate or subtruncate 
at the base and broadly rounded to subtruncate at the top viewed 
sideways, very deeply 3-lobed as seep from above, with compres-ed 
slightly keeled lobes, having a slight hump on their dorsal margin.
