162. E. Nyikae, Pax in Engl. Vji. Ost-Afr. C. 242. A tree up to 

 45 ft. high, M^hen young branching horizontally from the ground, when 

 old with a cylindric naked trunk, surmounted by a rounded crown of 

 curved ascending branches ( Volkens), succulent, leafio*s, 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 J 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 J lin. thick in diied specimens and scarcely 

 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 paiis J-| in. apart, rather slender, 

 widely diverging, grey, usually on sej:>arate 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-paus. 

 Cymes with peduncles 1-2 lin. long, bearing 1 sessile central involucre 

 and 2 on lateral branches 1-1 1 Im. long, glabrous. Bracts about 1^ 

 lin. long, suborbicular, entire, thin. Involucre 2J-3J lin. in diam., 

 cup-shaped, glabrous, with 5 glands and 5 rectangular, oblong or sub- 

 quadrate denticulate lobes; glands subcontiguous, IJ-lf 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 8 acute lobes J-J lin. long; styles 

 about 1^ lin. 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- 

 lucre, erect, about J in. high and J in. in diam., truncate or subtrunraie 

 at the base and broadly rounded to subtruncate at the top viewed 

 sideways, very deeply 3-lobed as seen from above, with compres.«-ed 

 slightly keeled lobes, having a slight hump on their dorsal mar^'in.
