Information
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 (3/4–2 1/2 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, 2 1/2–10 in. long, 1 1/4–4 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 triangular-acuminate, 3–5 1/2 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.

Notes
The Mozambique plants, which are T. usambarensis, 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.
