Origin and geographic distribution
Deinbollia grandifolia occurs from Sierra Leone to Togo and also in Cameroon, Chad, the Central African Republic and Gabon.
The wood of Deinbollia grandifolia is used in West Africa for house building and for planks. The fleshy fruit pulp is edible and the slightly oily seeds are eaten as well. Juice from the mashed inner bark is used as eye-drops to treat jaundice.
The wood of Deinbollia grandifolia is pinkish white and not durable.
Shrub or small palm-like tree up to 8(–15) m tall; bole up to 30 cm in diameter; bark surface grey, scaly; twigs often zigzag, reddish with small white lenticels. Leaves alternate, paripinnately compound, up to 100 cm long, with (5–)7(–10) pairs of leaflets; stipules absent; petiole 10–27 cm long, rachis up to 60 cm long, grooved; petiolules c. 1 cm long; leaflets often alternate, sometimes opposite, oblong to narrowly obovate, 13–30 cm × 5–8 cm, cuneate and asymmetrical at base, acuminate at apex, papery, minutely hairy or scaly, pinnately veined with 12–16 pairs of lateral veins. Inflorescence an axillary panicle 10–20(–50) cm long, yellowish or brownish short-hairy. Flowers unisexual, regular, 5-merous, greenish yellow; pedicel 1.5–2 mm long; sepals free, rounded, up to 5 mm long, nearly glabrous; petals free, ovate, up to 4 mm long, hairy at margins, inside with 2 small scales at base; stamens 8–17; disk annular; ovary superior, 2–3-lobed, style up to 5 mm long. Fruit a globose to ovoid berry up to 1.5 cm long, fleshy, glabrous, orange when ripe, indehiscent, 1-seeded. Seed ovoid, c. 1 cm long, brown to blackish. Seedling with hypogeal germination; epicotyl c. 6 cm long, hairy; first 2 leaves opposite, with 2 elliptical leaflets up to 3.5 cm × 1.5 cm.
Deinbollia comprises 30–40 species and occurs in tropical mainland Africa and Madagascar. The wood of many species developing into a tree is used. Deinbollia cuneifolia Baker is found from Guinea to Côte d’Ivoire and in Cameroon and Gabon. Although it is only a small tree up to 4 m tall, the wood is very hard and used for building. The fruit pulp is eaten. A steam bath, to which crushed bark and leaves are added, is prepared to overcome fatigue and as a cure for painful fevers.
Deinbollia fulvo-tomentella Baker f. (synonym: Deinbollia molliuscula Radlk.), a small tree of up to 9 m tall, occurs in the Central African Republic, Gabon, DR Congo, Uganda, Tanzania and Angola. In DR Congo its wood is used for construction.
At least 2 of the 7 endemic Deinbollia spp. of Madagascar are sought after for their wood. The wood of Deinbollia macrocarpa Capuron is used in boat building and for firewood. Deinbollia pervillei (Blume) Radlk. is appreciated for the quality and red colour of its wood, which is also used in boat building. It is also used as a support in vineyards and as firewood.
Deinbollia grandifolia is usually found in the undergrowth of deciduous forest. It is quite shade tolerant.
Genetic resources and breeding
As Deinbollia grandifolia is widespread and not intensively exploited there seem to be no serious threats.
The small stature of Deinbollia grandifolia and other Deinbollia spp. limits their usefulness as timber-producing trees.
