63. E. ampla, Hook. f. in Journ. Linn. Soc. vi. 20. “ Herbaceous 
plant 4 ft. high” (Mann). Stems probably arising from a perennial 
root, but “annual 2-3 ft. high” (Kalbreyer), 1-4 lin. thick, woody, 
simple or branching at the top, glabrous, brown, leafy above, naked 
below. Leaves alternate, with a whorl of 4-10 at the base of the umbel, 
spreading, 1}—4 in. long, 4-3 in. or more broad, lanceolate, acute, taper- 
ing from about the middle into a short petiole or acutely subsessile base, 
glabrous on both sides, perhaps glaucous beneath. Stipules none. 
Umbel 4-10-rayed and often with similar rays or with branches bearing 
umbels arising from the axils of the leaves below the umbel; rays 2-12 
in. long, 2-4 times forked, glabrous. Bracts sessile, opposite, 3-1} in. 
long, $-1 in. broad, ovate or triangular-ovate, acute, rounded, subtrun- 
cate or almost subcordate at the base, glabrous. Involucre solitary at 
the forks of the rays and terminal, about 1 lin. in diam., obconic-cup- 
shaped, with 4 glands and 5 subquadrate or rectangular shortly bifid or 
denticulate lobes with or without cilia, glabrous; glands 3-4 lin. m 
their greater and } lin. in their lesser diam., transversely oblong or 
somewhat crescent-shaped, or 2-lobed with 2 horns $-3 lin. long. 
Capsule 13-2 lin. in diam., smooth, glabrous; styles shortly united at 
the base, about 3 lin. long, bifid, with reeurving arms. Seeds 1 lin.

Very difficult to distinguish from the large forms of E. schimperian 
except by the larger glands, in which the lesser diameter is proportiona 
broader than in those of Z. schimperiana. Small examples from Cameroon
