Information
Shrub, small tree or liane to 30 m. Young branches with dense brown indumentum, consisting of short stiff fascicled hairs projecting slightly above pale-coloured weaker fascicled hairs, persisting as greyish arachnoid covering but old stems becoming subglabrous and purple-brown in colour. Leaf-rhachis 2.5–18 cm. long, indumentum as above. Terminal leaflet obovate to broadly elliptic, 6–18 cm. long, 3.5–14 cm. wide, apex shortly acuminate, base rounded to cuneate, rigidly chartaceous; midrib channelled above with fascicled hairs along length; lower surface of leaflet with scattered fascicled hairs, usually 4-armed, dense on midrib and nerves; lateral nerves to 6 pairs, arcuate ascending (see Fig. 4/1 and 4/2). Inflorescence terminal, to 30 cm. long; rhachis, bracts, bracteoles and pedicels densely pubescent as on young stems. Flowers fragrant. Sepals lanceolate to oblong-lanceolate, ± 5 mm. long, 1–1.5 mm. wide, fringed with reddish glandular hairs. Petals white, elliptic to oblong, to 5.5 mm. long, 2 mm. wide. Stamens 10; long-stamened flowers, 5 episepalous stamens to 5 mm. long, 5 epipetalous to 3 mm. long; short-stamened flowers, 5 episepalous stamens to 3 mm. long, 5 epipetalous to 1.5 mm. long (see note, page 9); filament-tube to 1.5 mm. long; anthers apiculate. Ovary ovoid, ± 1 mm. long, densely pilose; styles of short-stamened flowers to 5 mm. long, long-stamened flowers to 1.5 mm. long, puberulous. Fruit a ± obovoid follicle, to 2 cm. long, 1.4 cm. diam.; pericarp red, with dense velvety pubescence. Seed black, to 1.4 cm. long, 8 mm. diam.; aril white, to 6 mm. long, lobulate and somewhat fleshy.

Notes
VARIATION. A large range of leaflet-size is to be found in this species. Small bushy saplings which occur in quantity in the shrub-layer of most of the E. Tanganyika upland rain-forests have the largest leaflets whilst the smaller and rigidly chartaceous leaflets usually come from the top of the liane, either from the forest-canopy or on the forest-margins under conditions of higher light intensity. There is also a range of filament connation length, the longest staminal-tube being found in Uganda specimens and a progressive decrease is found southwards through Kenya to Tanganyika.
