600 CXXII. EUPHORBIACE® (BROWN). | Huphorbia. 
189, E. hermentiana, Lemaire in Ill. Hort. 1858, Miscel. 63. A 
succulent spiny bush (2-3 ft. high in the plants seen) or perhaps finally 
a tree, with whorls or clusters of strictly erect straight branches parallel 
with the stem. Branches 3-4-angled, constricted at varying intervals, 
1-2 in. broad across each face, dark green, with a somewhat feathered 
stripe or irregular marbling of whitish-green down each face, especially 
on the young branches; angles compressed, sinuately toothed, with the 
teeth 4-3 in. apart and projecting 1—2 lin., bearing a pair of widely 
diverging dark brown (finally grey) spines 2-3 lin. long, on small ovate 
horny shields. Leaves soon deciduous, thickly herbaceous, scarcely 
fleshy, on some plants small and not more than 3 in. long and } in. 
broad, elliptic-oblong, on others 14-21 in. long, 4-4 in. broad, oblanceolate 
or somewhat spathulate-lanceolate, obtuse, apiculate, tipering from 
much above the middle to the sessile base, glabrous, light green. 
Flowers and fruit unknown.—Boiss: in DC. Prodr. xv. ii. 82; Pax in 
Engl. Jahrb. xxxiv. 72, partly ; Berger, Sukk. Kupborb. 50, fig. 13. 
Lower Guinea. Gaboon, described from living plants cultivated at Kew! 
The plant collected by Laurent in the Lower Congo region, said to be used for 
hedges by the natives, referred to E. hermentiana by Pax in De Wild. & Durand, 
Contrib. Fl. Congo, i. 53, is probably a distinct species; I have not seen it. 
190. E. conspicua, V. £. Br. A succulent tree 15-50 ft. high, 
leafless and spiny, with a trunk 1-24 ft. thick. Branches and branchlets 
more or less whorled, radiately spreading and ascending-curved, with 
the trunk and main branches 3-8-angled, narrowed to the distant con- 
strictions ; branchlets mostly 3-angled, 1-1} in. broad across each face ; 
angles wing-like, sinuately toothed, with the teeth }—1} lin. apart and 
projecting 14-2 lin., bearing a pair of dark brown diverging spine 
1-3 lin. long on a dark brown horny shield which is decurrent to an 
acute point 1}—3 lin. below the spines. Flowering-eyes 2-24 lin, sbove 
the spines, separate or sometimes connected with the spine-shields by a 
horny border. Cymes 1-3 at each eye, crowded at the ends of the 
branchlets, with stout glabrous peduncles about 5 lin. long. Involueres 
apparently 24-3 lin. in diam., but all damaged by insects on the speci- 
mens seen, red (Welwitsch).—E. Candelabrum, Welw. in Annaes ee :
