natives travelling for miles to get it. It was obtained by Mr. Worthington, the 
secretary for native affairs, N..W. Rhodesia. I am of opinion that, like many 
other native remedies, its use is probably based on some superstition, and do not 
anticipate that it is of any practical scientific interest.” Col. Grant states that in 
Uganda it is rare and only found near villages, so that it may even have been carried 
thus far from the Zambesi Valley by the natives. 
11. S. angolense, V. #. Br. ‘An erect pyramidal growing 
tree, quite succulent. Stem 5 in. or more in diam., branched some 
2 ft. from the base” (Gossweiler). Branches as in S. Grantii, glabrous. 
Leaves thinly fleshy, 43-6 in. long, 1-13 in. broad, cuneately 
oblanceolate, obtuse or subacute, tapering from about 1-} in. below 
the apex to a narrow subsessile base, apparently narrowly revolute at 
the entire margins, with a prominent rounded (not winged) midrib 
beneath, glabrous on both sides, pale green (Gossweiler). Cymes 
axillary, about 34 in. long including the 4-3 in.-long peduncle, 
1-1} in. broad, rather lax, about 4 times forked, with a sessile involucre 
m each fork and at the tips of the ultimate branchlets, thinly and 
minutely pubescent on the ultimate branchlets, otherwise glabrous ; 
bracts about % in. long and broad, subquadrate, subacute, minutely 
puberulous on both sides. Involucre nearly } in. in diam., very 
shallowly basin-shaped, open or notched to half-way down on one 
side, with a very spreading entire rim-like gland, finely pubescent 
outside; lobes wholly overtopping the gland, with a few scattered 
hairs on both sides. Ovary rather densely white puberulous on all 
parts, with the perianth-lobes 3—1 Jin. long, as long as or longer than the 
young ovary and adpressed to its angles, linear or subulate, obtuse or 
acute, incurved at the tips, puberulous; styles united at the base, 
shghtly dilated and thickened at the apex, not at all bifid. 
Lower Guinea. Angola: near Malange, Gossweiler, 997 ! owe 
To this species may possibly belong a specimen too immature to determine, 
collected by Monteiro in Angola, about 100 miles inland from Ambriz, which is stated 
on the label to grow about 12-14 ft. high, with thick stems and leaves. According 
to Gossweiler S. angolensis is « evidently planted near the natives’ d-vellings,” so is 
probably used by them medicinally or as a poison. , 
_ 12. S. cymosum, V. Z. Br. Stem (glabrous) and habit as in 
S. Grantii. “Leaves 54-7 in. long, 14-2 in. broad, lanceolate, apex 
broken, cuneately narrowed for about } of their length into a stout 
petiole 4-2 in. long, subentire or minutely serrulate and sometimes also 
somewhat crenate, rather thick and subrigid, probably fleshy when 
alive, glabrous on both sides ; midrib prominent and rounded at the 
base, but apparently not prominent at the upper half of the leaf 
beneath. Cymes axillary, 44-5 in. long (including the 14-1} in.-long 
peduncle), 2-21 in. broad, dichotomously much-branched, corymb-like 
or flat-topped ; peduncle and lower divisions glabrous, upper branches 
puberulous or shortly pubescent; bracts 14-12 lin. long and broad, 
broadly cuneate or cuneately subquadrate, slightly hooded ‘at( the 
subtruncate apex, puberulous on both sides. Involucre rather ‘more
