598 CXXI, EUPHORBIACEA (BROWN). | Luphorbia. 
Flowering-eyes touching the shields, producing 2—3 cymes with peduncles 
2-8 lin. long, each bearing 3 involucres, with the lateral on branches 1}- 
24 lin. long, glabrous. Bracts membranous, suborbicular, about 1} lin. 
in diam., obtuse or apiculate, entire or minutely denticulate, glabrous. 
Involucre subsessile or very shortly pedunculate, 33-4 lin. in diam. and 
1} lin. deep, shallowly cup-shaped, glabrous, with 5 glands and 5 short 
transverse fringed lobes; glands contiguous, about 1% lin. in their 
greater diam., reniform or transversely oblong, entire, unequally 2- 
lipped or with the inner margin turned up. Ovary subsessile, only 
partly exserted from the involucre, glabrous, with a calyx of about 
5 filiform segments 3-1 lin. long; styles 1 lin. long, united at the base, 
thickened and 2-lobed at the apex. Fruit and seeds not seen.

185. E. garuana, V. #. Br. A succulent leafless spiny bush, 
grown as a hedge plant, about 6 ft. high, probably attaining much 
larger dimensions and perhaps becoming a tree. Branch of the spect 
men seen 10 in. long, 1 in. (and probably more) in diam., con- 
stricted into 5 oblong or narrowly elliptic segments 14-24 in. long, si 
angled, with the solid central part about as thick as the wing-like angles 
are broad; angles not toothed or sinuate at the margins. Spines 1-1, 
lin. long, in pairs, diverging, with or without a pair of minute auricles 
(not prickles) at their base and almost touching them, blackish-brown, 
on small subhorny broadly obovate blackish-brown (possibly discoloured 
in drying) shields 2-3 lin. apart, apparently deciduous. Flowering- 
eyes touching the spine-shields, producing 1-3 cymes on peduncles 
4-43 lin. long, bearing 8 involucres, with the central male and the 
lateral bisexual, glabrous. Bracts suborbicular, about 2 lin. In diam., 
very concave. Involucres 3-34 lin. in diam. when fully developed, 
about 14-1} lin. deep, broadly and shallowly cup-shaped, glabrous, 
with 5 glands and 5 subquadrate deeply fringed lobes ; glands con 
tiguous, 13-2 lin. in their greater diam., transverse, somewhat half- 
circular, entire, apparently deflexed at the ends. Ovary (very yours: 
only seen in very immature bisexual involucres) glabrous, with a 
calyx at its base, cut into several filiform segments; styles 3, rather 
more than 1 lin. long, probably longer when mature, very shortly 
united at the base, stout, bifid at the apex. Capsule and seeds not seen 
Upper Guinea. Cameroons: Garna, Ledermann, 5140! 
The spine-shields of this species are softer and less horny than i 
seen; also they appear to be quickly deciduous from all but the one or tw 
segments of the branches.
