rib, indistinctly looped almost at the margin, usually undivided, raised 
on the lower surface; tertiary nerves indistinct, more or less parallel ; 
petiole very stout, up to 3 lin. in diam. and } in. long, shortly 
pubescent or glabrous. Male flower-heads borne on the previous year’s 
growth, in fascicles: peduncles glabrescent, }-2 in. long. Bracts of

Rudimentary ovary obconic, truncate, pilose towards the top. Female 
flowers: Peduncle about 3 lin. long, sparingly pubescent. Bracts of the 
Involucre as in the male. Calyx cupular, very small, and shortly lobed, 
coriaceous, glabrous. Ovary 4-celled, ovoid, 24 lin. in diam., whitish- 
tomentose, almost hidden by the reflexed spreading styles; styles 4, 
reflexed, fan-shaped, lobed to the middle, 24 lin. long, 3 lin. broad, 
lobes numerous, linear, subterete. Fruit subglobose, 3-4-celled,

5. U. benguelensis, Wiill. Arg. in Journ. Bot. 1864, 332, partly. 
A tree, usually branched from the base; branchlets stout, puberulous. 
aves often crowded towards the ends of the branchlets, obovate or 
elliptic, rounded at the base and apex, or sometimes very slightly cuneate 
at the base, but not decurrent on the petiole, 3-5 in. long, 2-3 in. broad, 
rigidly coriaceous, scaly on the upper surface, floccose-pubescent below, 
distinctly lepidote, especially below; lateral nerves 8-12 on each side, 
very prominent and sharp on the lower side, very indistinetly looped 
almost at the margin; tertiary nerves parallel and rather close, not 
‘istble above, very faint below; petiole 3-1 in. long, nearly glabrous. 
Male flowers not seen. Female flowers very shortly pedunculate. 
Braets of the involucre oblong, obtuse, about 4 lin. long and 2 lin. broad, 
rorlaceous, adpressed-pubescent on the outside. Calyx irregularly 
bed, pilose on the outside. Ovary 3-celled, densely pubescent ; styles 
°, reflexed and covering the upper half of the ovary, much laciniated,
