 {inch var,). A shrub or small tree reaching 18 ft. in height, slightly 

 branched ; branchlets slender, ultimate branchlets about 1 lin. thick 

 with internodes varying very much in length (f-2J in.), surface grey- 

 or reddish-brown, the younger parts and petioles bearing short 

 whitish hooked hairs. Leaves varying considerably in size and shape, 

 oblong-elliptic to elliptic, more rarely oblanceolate-oblong, apex 

 more or less abruptly acuminate, generally more or less grossly 

 dentate below the cusp the toothing extending sometimes half-way 

 down the leaf, base unequal, obtuse to rounded, 2J-10 in. long, 

 1 J-4 in. wide, membranous, shining above, paler beneath, glabrous ; 

 lateral nerves 7-12 on each side, ascending and uniting within the 

 margin, impressed above, prominent beneath ; petiole 2-5 lin. long. 

 Stipules triangulur-acuminate, 3-5 J lin. long, somewhat persistent. 

 Inflorescences 1-4 on a short axillary branch, densely covered with 

 short whitish hooked hairs ; peduncles 2 lin. or less in length, becoming 

 dilated above into a top-shaped receptacle. Receptacle 3-4 lin. in 

 diam., bordered with numerous short bluntly rounded lobes. Male 

 flowers 2-androus, the 2 short blunt perianth-lobes densely pubescent 

 on the outside ; filaments dilated above into a broad suborbicular 

 connective on the inner face of which the separate broadly oval 

 anther-halves are borne. Perianth-tube of female flower similar in 

 pubescence to the male perianth ; projecting style-arms 1 lin. long, 

 linear, recurved. Receptacle with ripe fruit subglobose, 5 lin. in 

 diam.— Engl. Pflanzenwelt Afr. i. ii. 647 ; Hiern in Cat. Afr. PL Welw.

The Mozambique plants, which are T. usaynbarensis, Engl., differ in the 

 glabrescent character of the young shoots and inflorescences. The more 

 marked toothing of the leaf on which Engler relies as a distinction from 

 T. kamerunensis occurs in a still greater degree among the variable leaves of 

 that species.
