084 CXXII. EUPHORBIACEX (BROWN). | Luphorbia. 
usually separate and more or less extending above and below the spines 
into an acute point, but sometimes in places connected by a continuous 
horny border. Flowering-eyes touching the spine-shields, 1-2 lin, 
above the spines, producing 1-3 or wore cymes, crowded along the 
margins. Cymes 5-6 lin. long, pedunculate, glabrous, bearing 3 invo- 
lucres, with the middle one sessile and the lateral on branches 143-2 lin. 
long; peduncle 1-1} lin. long. Bracts about 1 lin. long and broad, 
seale-like, broadly ovate, obtuse. Involucre 2 lin. in diam., cup-shaped, 
glabrous, with 5 glands and 5 erect deltoid acute or toothed lobes ; 
glands not contiguous, 3-1 lin. in their greater diam., transversely 
oblong, with a slightly raised margin all round. Ovary with a calyx 
at its base of 3 deltoid lobes cut into 2—4 filiform segments, exserted on 
a stout angular and somewhat furrowed pedicel 2-24 lin. long, and curved 
to one side, glabrous; styles 1 lin. long, united at the basal third, with 
stout spreading arms, channelled on the upper side, shortly 2-lobed at 
the apex. Capsule not seen, but probably rather fleshy.

161. E. angularis, Klotzsch in Peters, Reise Mossamb. Bot. 92. 
A succulent leafless spiny bush, about “16 feet high, with thick stems 
and radiating ascending branches” (Kirk), glabrous. Branches deeply 
constricted into joints 3-8 in. Jong and 2-44 in, in diam., broadly 
3-winged, with a rather small solid central part; wings 1-24 in. broad, 
wavy and irregularly lobed or sinuate, with continuous grey horny 
margins. Leaves rudimentary, scale-like, rigid, 1-14 lin. long, sub- 
quadrate, obtusely pointed or rourded at the apex, strongly Te 
curved, very concave lengthwise, central part deciduous, leaving 
2 small rigid hooks partly recurved between the bases of the spines. 
Spines 2-5 lin. long, in pairs 4-1 in. apart, diverging, grey. Flowering- 
eyes }-} in. above the spines. Cymes solitary or 2 together, with 
stout peduncles 3-2 lin. long, bearing 3 involueres, with the lateral on 
stout branches 1-2 lin. long, glabrous. Bracts suborbicular, concave, 
about 14-2 lin. in diam., entire or slightly denticulate. Involucre 
23-33 lin. in diam., cup-shaped, glabrous, with 5 glands and 5 eg 
angular or subobovate erect denticulate lobes ; glands contiguous, 1}-2 
lin. in their greater diam., transversely elliptic-oblong, but with the 
inner margin less curved than the outer and more or less upeurved, 
deflexed at each end and in fruit becoming wavy along the outer margi»- 
Ovary sessile and together with the greater part of the styles included 
in the involucre, glabrous, with a shortly 3-lobed cupular calyx at its 
base ; styles 2 lin. long, united for half their length, slightly spreading 
above, entire, with thickened truncate rugose stigmas, slightly excavat 
on the upper side. Capsule just exserted from the involucre, eree’ 
3 lin, high and 6-7 lin. in diam., very truncate at the apex and ee 
very deeply 3-lobed as seen from above, the much compressed lo . 
subquadrate in outline viewed sideways, not fleshy, with subwoody er 
walls } lin. thick, glabrous, red, having a persistent somewhat fleshy 
$-lobed calyx at the base, its lobes about I lin. long, ovate, obtuse OF
