’ The branches of this plant seem always to originate from buds in the axils of the 
cluster of leaves at the base of the peduncle, never from those of the alternate leaves 
on the lower part. After fruiting the leaves and umbels fall, and the next season’s 
growth is developed from the apex of the previous year’s branches,

(Johnston). Stems or branches of the specimens seen herbaceous or 
sub-woody, 14-2 lin. thick, terete, glabrous. Leaves alternate, thin, 
23-6 in. long, 2-2 in. broad, lanceolate, acute or acuminate and apiculate 
at the apex, tapering from above or below the middle into a petiole 
+4 in. long, glabrous on both sides. Stipules none. Umbel terminal 
or with the branch ultimately developing beyond it, composed of 3-6 
rays 2-5 in, long, once or twice forked, glabrous. Bracts 24-6 in. long, 
13-5 lin. broad, elliptic or elliptic-ovate to suborbicular, obtuse or 
rounded at the apex and base, apiculate, glabrous on both sides. Invo- 
lucres on very short peduncles, solitary in the forks or at the ends of 
the ray-branches of the umbel, about 24 lin. in diam., cup-shaped, 
glabrous, with 4 glands and 5 subquadrate-ovate lobes, minutely 2-toothed 
at the apex and ciliate; glands 3-1 lin. in their greater diam., trans- 
versely oblong, half-circular, or subrectangular, with 2 teeth or short 
horns, sometimes reduced to minute points at the outer angles. Capsule 
3-33 lin. in diam., glabrous, exserted on a long recurved pedicel ; styles 
about } lin. long, very shortly united at the base, rather deeply bifid at 
the apex, suberect. Seeds 13 lin. long, subglobose-ellipsoid, tuberculate.

On the respective labels, Sir Harry Johnston states that this is a tree and Volkens 
that it is a laxly branched shrub 10 ft. high. 1 find no difference whatever between 
- Engler: and #. pseudo-engleri, both leaves and glands vary considerably when a 
sufficient number of specimens is examined.

long, varying from pilose to glabrous, naked at the lower 14-1} in., 
with prominent leaf-scars, leafy above, dark brown, or perhaps purplish 
when alive. Leaves alternate, with a whorl of 5 at the base of the
