66. E. longecornuta, Pax in Engl. Hochgebirgsfl. Trop. Afr. 286. 
Annual, 2-6 ft. high, with 1-2 stems from the same root, sometimes 
{from injury) forked or subumbellately branched a few inches above the 
base, glabrous, leafless on the lower part, with raised leaf-scars. Leaves 
alternate, with a whorl of 5-7 at the base of the umbel, 1}~4 in. long, 
3-} in. broad, lanceolate, acute or subacuminate, tapering to a shortly 
petiolate or subsessile base, glabrous on both sides. Stipules none. In- 
florescence paniculate, consisting of a terminal umbel of 5-7 cyme-rays 
4-8 in. long and 2-4 times forked, with several similar cymes arising 
from the axils of the upper leaves. Bracts sessile, 3-1} in. long, }-} in. 
broad, ovate, oblong-ovate or ovate-lanceolate, acute, subtruncately 
rounded at the base. Involucre shortly pedunculate, excluding the 
glands, about 1 lin. in diam., somewhat pear-shaped, glabrous outside 
and within, with 4 glands and 5 oblong-ovate or subquadrate slightly 
notebed and minutely ciliate lobes; glands 3-3} lin. in their greater 
diam., crescent-shaped, with 2 linear horns 3 lin. or perhaps more long, 
often toothed at the apex. Capsule exserted, about 2 lin. in diam., 
glabrous ; styles about 3 lin. long, free nearly to the base, bifid at the 
apex. Seeds about 1 lin. long, ellipsoid, smooth, with a small caruncle.—

_ This is very closely allied to H. schimperiana, Scheele, and structurally is only 
distinguishable by the larger horns of the involucral glands ; possibly it may be only 
a form of that species and like it varies very much in stature and appearance, some 
of the specimens from the moister regions near the Equator being much larger than 
those from Abyssinia, whilst others are identical with them. Pax has described it 
a8 perennial, but his type specimens and all others that I have seen with roots are 
annual. 
67. E. petitiana, A. Rich. Tent. Fl. Abyss. ii. 241. Perennial, or 
perhaps biennial? Stems usually 2 or more to a root, erect, 6-10 in. 
high, often clothed with a number of short erect or ascending very leafy 
ranches, glabrous. Leaves alternate, rather crowded, at first ascending, 
finally reflexed, sessile, {-1} in. long, 1}-3 lin. broad, oblanceolate or 
somewhat spathulate-lanceolate, acute or obtuse, apiculate, tapering from 
above the middle to the base, very minutely denticulate at the apical 
part, glabrous on both sides. Stipules none. Umbel terminal, 2}-3 in. 
in diam., of 5 once or twice forked rays 13-2} in. long or occasionally
