Var. sudanica, Hutchinson. Fruits sessile or subsessile-—U. Guignardi, var. 
sudanica, Beille, 1.c. 67. 
North Central. Upper Shari: Gribingui; between Fort Crampel and the 
Kaya M’Bra, Chevalier, 6450! 
Var. sudanica may possibly be a distinct species, but as only fruiting specimens 
are known it seems preferable to retain it for the present as a variety. 
U. Guignardi was described by Beille as having “ hispidulous filaments,” thus 
differing from U. guineensis by this character. The filaments in his type, however, 
are quite glabrous and his plant is indistinguishable from typical U. guineensis. 
Imperfectly known species. 
12. U. Teusczii, Pax in Engl. Jahrb. xix. 79. A tree; branch- 
lets stout, slightly grooved, very sparingly puberulous or glabrescent. 
Leaves elliptic or obovate-elliptic, rounded at the apex, slightly cuneate 
at the base, 33-5 in. long, 2-34 in. broad, rather rigidly coriaceous, 
glabrous and slightly rough on both surfaces, brown above (when dry), 
reddish below ; lateral nerves 9-10 on each side, spreading, gradually 
fading before reaching the margin; tertiary nerves subparallel, not 
raised and rather faint; stipules not seen; petiole 3-1 in. long, very 
Sparingly pilose or glabrous. Male flowers not known. Females clus- 
tered at the base of the branchlets; peduncle 24 lin. long, glabrous. 
Bracts of the involucre oblong, rather strongly keeled, about 4 lin, long, 
13-3 lin. broad, entire, coriaceous, glabrous. Calyx irregularly lobed ; 
lobes pilose towards the top. Ovary 4-celled, glabrous, nearly hidden 
by the 4 reflexed very much divided styles. 
Lower Guinea. Angola: Malange, Teuscz, 423! 
13. U. Pyneertii, De Wild. Etudes Fl. Bas- et Moyen-Congo, ii. 274, 
71. A large tree. Leaves obovate, obtuse, long-cuneate at the base, 
$12 in. long, 34-44 in. broad, coriaceous, glabrous on both surfaces ; 
lateral nerves 12-15 on each side, oblique, obscurely reticulate ; petiole 
1}-2 in. long. Male inflorescences axillary; peduncle 1-2} in. long. 
Bracts of the involucre numerous, up to ? in. long and 4 in. broad, 
obovate, obtuse. Calyx villous inside towards the base, otherwise 
glabrous. Filaments glabrous. Rudimentary ovary glabrous, a little 
longer than the calyx. Female flowers and fruits not known.
