about 4 simple rays 3-10 lin. long, each with 1 involucre and a pair of 
orbicular-obovate thin bracts about 2 lin. long and broad, glabrous. 
Involucre shortly pedunculate within the bracts, about 2 lin. in diam., 
cup-shaped, glabrous, with 5 glands and 5 rounded subentire lobes 
slightly woolly on their inner surface ; glands 3-3 lin. in their greater 
diam., suborbicular, or transversely elliptic, yellow (Thonning). Ovary 
globose-trigonous, glabrous, exserted on a pedicel about 2 lin. long and 
curved to one side; styles about 1 lin. long, shortly united at the 
base, then widely spreading, emarginate or minutely 2-lobed at the 
apex. Capsule and seeds not seen.—Boiss. in DC. Prodr. xv. ii. 6.

A specimen (Dalziel, 327) from Katagum district, Northern Nigeria, is probably 
this Species, but the styles are deeply bifid with diverging recurved tips. Also a 
Specimen collected near Lome in Togo (Busse, 3260) probably belongs here. In 
Thonning’s type specimen the umbel is really terminal, but a branch growing out 
at its base and falsely appearing to be continuous with that which bears it, makes 
the umbel seemingly lateral. 
_ 98. E. gossypina, Pax in Engl. Jahrb. xix. 119. A bush 2-3 ft. 
high, formed of a mass of long slender naked succulent interwoven 
stems and branches, leafy only on the young growth for a short period. 
Branches ascending or making a right-angle with the stems or main 
branches or becoming pendulous, 2-34 lin. thick in the specimens seen, 
terete, with small crescent-shaped leaf-scars, glabrous. Leaves alternate, 
Whorled at the base of the umbel, sessile, reflexed, soon deciduous, those 
on the stem 3-1} in. long, 1-24 lin. broad, lanceolate or linear-lanceolate, 
acute, narrowed towards the base, the upper sometimes shorter and 
broader and becoming more elliptic or ovate, those of the whorl usually 
3-5 lin, long and 13-34 lin. broad, ovate to orbicular, very obtusely 
tounded to acute and apiculate, but sometimes like those of the stem, 
all glabrous on both sides. Stipules none. Umbel terminal, simple, 
With a central shortly pedunculate involucre which is male and deciduous 
and 4-5 rays 3~I} in. long, each with 1 hermaphrodite involucre and a 
Pair of reflexed elliptic obtuse bracts about 3 lin. long and 2 lin. broad, 
glabrous. Involucres on peduncles 13-2 lin. long, broadly and shallowly 
cup-shaped, about 4 in. in diam., glabrous, but with a dome-like mass 
° Very white woolly bracteoles filling the interior, with 5-6 large 
glands and 5-6 subquadrate lobes, notched or slightly toothed at the top, 
with a fringe of very fine weak hairs, which appear to arise from the inner 
Surface and are only seen (on dried specimens) when the lobe is placed 
rm Water ; glands turned outwards, 14-2 lin. in their greater diam., 
eared elliptic to suborbicular, flattish, entire or slightly crenate 
: © outer margin, Ovary exserted above the dome of woolly bracts, 
rect, glabrous ; styles 11 lin. long, united at the base, deeply bifid at
