552 CXXII. EUPHORBIACEE (BROWN). [ Euphorbia, 
Leaves alternate ; petiole 2-4 lin. long; blade 6-8 lin. long, 3-34 lin. 
broad, or perhaps larger, elliptic-oblong, obtuse, cuneately rounded into 
the petiole, longitudinally folded in the specimens seen, somewhat fleshy. 
Stipules none. Bracts under the involucres sessile, }—4 in. long and as 
broad or broader than long, orbicular-rhomboid or transversely rhomboid, 
very obtuse, longitudinally concave-folded so that the pairs form a sort 
of cup. Involucre solitary, terminal, sessile, about 1} lin. long and 1} 
lin. in diam., subcylindric-obconic, glabrous outside, with 5 glands and 
5 oblong minutely 3-toothed pubescent and ciliate lobes; glands $-} 
lin. in their greater diam., transverse, somewhat elliptic-oblong and 
2-lipped, with the small rounded entire inner margin inflexed and the 
much larger rounded minutely crenate outer margin spreading. Ovary, 
capsule and seeds not seen, all the involucres examined being male. 
Lower Guinea. Angola: on sandy maritime hills between Mossamedes and 
Cabo Negro, also near San Antonio, Welwitsch, 634! 
The sap is stated to have a balsam-like odour. 
96. E. incurva, V.Z.Br. Stem in the only specimen seen (a piece 
9 jin. long) apparently succulent or herbaceous, but possibly a branch 
from a shrub, about 2 lin. thick, tapering upwards, branching, glabrous. 
Branches alternate, numerous, subequidistant, 3-5 lin. apart, 13-4 In. 
long, 1 lin. thick, horizontally spreading at their basal part, then up- 
curved, leafy at the tips, naked and marked with prominent leaf-scars 
below, glabrous. Leaves alternate, 3-3 in. long, 1-14 lin. broad, linear- 
lanceolate, with inrolled margins, acute, somewhat rounded or tapering 
into a petiole 1-14 lin. long, glabrous above, puberulous with minute 
curved white hairs beneath. Peduncles axillary, solitary, 3-1 lin. long, 
bearing a pair of bracts and 1 involucre, glabrous. Bracts 13-1} lin. 
long, 4-3 lin. broad, somewhat rhomboid-elliptic, acute, with incurved 
margins, puberulous on both sides. Involucre sessile between the 
bracts, about 1 lin. in diam., cup-shaped, puberulous, with 4 glands 
and 5 quadrate puberulous densely ciliate lobes; glands not contiguous, 
4-3 lin. in their greater diam., transversely oblong or subquadrate, 
entire, white-puberulous on the back and more or less on the upper OF 
inner surface, densely ciliate. Ovary exserted and curved to one side, 
densely covered with minute curved white hairs; styles } lin. long, 
free, erect, bifid at the apex, puberulous. 
Mozamb. Distr. German East Africa: Sonjo Sale, Merker, 579! 
A very distinct species, easily recognised by the curvature of its regularly p 
branches and the puberulous glands of the involucre.

97. E. lateriflora, Schum. d: Thonn. Beskr. Guin. Pl. 252. Stems 
3 ft. or more long, scrambling, fleshy, terete, with lax hanging branches, 
marked with the scars of fallen leaves, glabrous, glaucous ( Zhonning ) 
Branches alternate or sometimes somewhat clustered, 1-3 lin. i 
leafy when young. Leaves alternate, 1-3 lin. apart, with a whorl a 
the base of the umbels, sessile, 1-14 in. long, 1-24 lin. broad, line 
lanceolate or linear, acute, tapering to the base, entire, glabrous, beer 
the midrib prominent beneath, veins invisible. Umbels terminal, w!
