Shrub up to ± 5 m high, tree to 15 m tall with trunk 30-40 cm diam., or liana up to c. 15 cm thick. Leaves (2-)3-6(-7)-jugate. Folioles (sub)opposite to alternate, oblong-elliptic to lanceolate, (1.5-)2-4(-4.5) times as long as wide, (3.5-)9-18(-25) × (1.5-)3.5-7(-10) cm, glabrous above exept for the impressed, usually pubescent midrib above, beneath sparsely appressedpuberulous to (sub)glabrous; apex usually caudate-acuminate, the acumen (1-)1.5-2(-3) cm long; lateral nerves (7-)9-14(-18) pairs. Inflorescences terminal to axillary or, more rarely, borne below the leaves, widely branched, up to at least 55 cm long, pubescent to puberulous, often mixed with a patchy, arachnoid to mold-like, white indumentum, this sometimes also present on leaflets beneath. Flowers (Feb.-Oct.) yellowish, 4(-5) merous. Fruits (July-Dec.), subglobose to obovoid-ellipsoid, 1.5-2.5 × 1.5-2 cm, smooth, glabrous. — Figs 2F; 13.

NOTES. — The synonymy of this species reflects its extreme variation in habit from a medium sized tree (T. lescrauwaetii, T. arborescens) to a vigorous liana (T. altescandens, T. scandens). VAN DER VEKEN (1960) separated the species he recognized based on their habit only, which seems to me not acceptable. I have tried to find additional characters, but failed. Therefore I conclude that this variation has to be accepted as belonging to a single species. This is strongly supported by a pair of specimens collected in the Epulu area in Ituri, in eastern Congo (Kinshasa): Hart 411 (a tree) and Abena in coll. Hart 1656 (a liana). These specimens are otherwise so much alike that separation in two different species on account of their difference in habit seems quite unacceptable.
