Trémaux. 
The above is compiled from Trémaux’s figure and description. I have not seen 
a specimen of it. Those referred to this species by Pax, Sehweinfurth, Hiern and 
Berger cannot belong to it, on account of their different habit, much broader 
wing-like angles, and much smaller solid central part. Possibly the plant collected 
by Cienkowsky in Fosoki, quoted by Schweinfurth (Beitr. Fl. Aethiop. 36), may be 
the true E. Candelabrum, but I have not seen it. 
187. E. platyacantha, Pax in Engl. Jahrb. xxxiv. 84. A succu- 
lent spiny leafless tree 30-40 ft. high, with a rounded crown, The 
type specimen consists of a terminal branch constricted 6 in. below 
the apex, 3-1} in. square, 4-angled, with a solid central part about 
4 in. Square; angles wing-like, even or scarcely toothed. Leaves 
rudimentary, seale-like. Spines 3-4 lin. long, in pairs }-} in. apart, 
widely diverging, with a pair of recurved prickles 3-3 lin. long imme- 
diately above them, on narrow grey horny -spine-shields, decurrent 
to } or 3 of the way down to the shield below. Flowering-eyes in the 
axils of the small prickles. Flowers and fruit unknown.—F£, Stuhl-

188. E. quadrialata, Pas in Engl. Jahrb. xxxiii. 286. A tree 
up to 60 ft. high, narrowly pyramidal, with a cylindric trunk and 
stant or irregular groups of stout ascending cylindric branches, naked 
below, ending in large rounded brush-like dense heads of secondary 
and tertiary branches, succulent, leafless, spiny, glabrous. Secondary 
ranches spreading, with distant groups of branchlets, 3-1 in. in diam., 
With 3-4 wing-like angles, apparently not glaucous; angles thin, 
slightly toothed or nearly even. Leaves minute, rudimentary. Spines 
1~3 lin. long, slender, in pairs 3-5 lin. apart, diverging, dark grey, on 
small ovate horny shields 1-14 lin. long, shortly acute below the spines, 
grey. Flowers and fruit unknown.—Pax in Engl. Jahrb. xxxiv. 74
