 thus far from the Zambesi Valley by the natives. 



U.S. angolense, A'^. E. Ih\ *' An erect pyramidal growing 

 tree, quite succulent. Stem 5 in. or more in diam., branched some 

 2 ft. from the base " {Gossiueller). Branches as in S. Grantii, glabrous. 

 Leaves thinly fleshy, 4J-6 in. long, 1-lJ in. broad, cuneately 

 oblanceolate, obtuse or subacute, tapering from about 1-J in. below 

 the apex to a narrow subsessile base, apparently narrowly re volute at 

 the entire margins, with a prominent rounded (not winged) midrib 

 beneath, glabrous on both sides, pale green {Gossweiler). Cymes 

 axillary, about "Mi in. long including the J-| in. -long peduncle, 

 l-l J in. broad, rather lax, about 4 times forked, with a sessile involucre 

 in 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 J 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 J-1 lin. long, as long as or longer than the
