Remarks: Info from: PROTA4U Evergreen, medium-sized to fairly large tree up to 35(–40) m tall; bole branchless for up to 20 m but often low-branching, straight and cylindrical or irregular, up to 90(–100) cm in diameter, with buttresses; bark surface nearly smooth, but with fine longitudinal grooves and lenticels, becoming flaky, grey-brown, inner bark fibrous, brownish to reddish; crown often long and narrow, often with drooping branches; twigs usually glabrous, with lenticels. Leaves alternate, paripinnately compound with 2–5 pairs of leaflets; stipules fused, up to 1.5 cm long, clasping the twigs, persistent; petiole and rachis together 5–22 cm long, grooved; petiolules 1–4 mm long, twisted; leaflets opposite, elliptical to oblong or lanceolate, 2–15 cm × 1–6 cm, asymmetrical at base, acuminate at apex, thinly leathery, glabrous, pinnately veined with 10–15 pairs of indistinct lateral veins. Inflorescence a terminal, flat-topped panicle 4–8 cm long, usually glabrous. Flowers bisexual, zygomorphic, with 2 bracteoles up to 3.5 cm long at base; pedicel 1.5–3 cm long; sepals 4, 1–1.5 cm long, 1 broader than the other 3 and 2-toothed; petals 5, free, unequal, bluish, upper one largest, up to 4.5 cm × 2.5 cm, lateral 2 up to 3 cm × 2.5 mm, lower 2 minute; stamens 9, fused at base, usually 3 fertile, large, up to 3.5 cm long and 6 rudimentary; ovary superior, linear, 1–1.5 cm long, hairy, with long stipe, 1-celled, style 2–2.5 cm long. Fruit an oblong, flattened pod 8.5–20 cm × 2.5–6 cm, glabrous, dehiscing with 2 spiralling woody valves, 3–8-seeded. Seeds rectangular, flattened, 1.5–2.5 cm × 1–2 cm, glossy dark brown, seed coat hard. Seedling with epigeal germination; hypocotyl 5–12 cm long, epicotyl 4–7 cm long; first 2 leaves opposite, with 2–3 pairs of leaflets. In the nursery seedlings are about 30 cm tall after 4 months and 60 cm tall after 15 months. In Guinea 6-years-old saplings showed a mean annual height growth of 85–130 cm, but in DR Congo planted trees were only 4.5 m tall after 11 years and had a high mortality. Fruits are eaten by monkeys and large rodents, which may serve as seed dispersers. Paramacrolobium comprises a single species and seems to be related to Cryptosepalum. | |
