Information
A tree, 10–18 ft. high; branches spreading, flexuous. Leaves mostly ternate, rarely opposite, oblong, obtuse or obscurely acuminate, subacute or obtuse at the base, 4–6 in. long, 1 3/4–2 1/4 in. broad, coriaceous, glossy above, dull green beneath, almost glaucous; secondary nerves subhorizontal, about 10–15 on each side, very faint; veins obscure; petioles 6 lin. long. Flowers in small axillary clusters, sessile. Calyx 1/2 lin. long; sepals broadly ovate, very obtuse. Corolla-tube white, 3 1/2 lin. long, slightly widened above the middle; lobes yellow, spreading, roundish-ovate, 3/4 lin. long. Carpels 2, 2-ovuled. Berries obovoid or pear-shaped, 5–6 lin. long.
Distribution
Angola Lower Guinea Golungo Alto; by the Cuango stream, Welwitsch, 5981!Angola South Central Lunda; Luachim River, Buchner, 621!
Notes
Welwitsch states (in MS.) that this tree is extremely rich in a milky juice which dries to an elastic rubber. A plant collected in Lunda, on the Lulua River, by Pogge (1630!) was referred by Hallier f. l.c., to Hunteria pycnantha, which it certainly is not, but the specimen is too defective for determination.
