Albizia ferruginea is a tree, 6-40 m high with a beautiful spreading crown. Bole nearly straight; bark rough, thick, peeling off in older trees. Young branchlets densely rusty, pubescent or sometimes subtomentose. Slash light brown with reddish patches. Leaves bipinnate, consisting of 3-5 pinnae oppositely arranged, terminal pinnae; terminal pinnae pairs on the leaf stalk have 15-16 leaflets, which can grow up to 2cm long and 0.8 cm wide. Leaflets oblong, tip and base round; smooth on top and hairy underneath. Leaf indumentum red. Flowers greenish-cream in tight clusters, calyx 3-6 mm long covered with rusty hairs. Stamen numerous, filaments up to 5 cm, staminal tube not or scarcely exserted beyond corolla. Fruit a pod, 15-20 cm long and 4 cm wide, reddish-brown glossy and veined; containing 9-12 flattened seeds, seed 7-10 mm long and 4.5-8 mm wide. The genus was named after Filippo del Albizzi, a Florentine nobleman who in 1749 introduced A. julibrissin into cultivation. The specific epithet refers to the colour of the pods.
Ecology

Native range
Angola, Burkina Faso, Cote d'Ivoire, Guinea-Bissau, Nigeria, Senegal, Uganda
Seed storage behaviour orthodox.
A. ferruginea is a forest emergent commonly found in woodland, lowland rainforest and scrub vegetation.
Direct seeding is preferred in propagating this species.
Poison: The bark is reportedly poisonous.
Forage legume eaten by goats, reports from Nigeria lists it highest in a sample of 44 species in protein content and crude fibre.
Apiculture: The tree provides nectar for bees.
Branches are used as firesticks.
Timber: A. ferruginea wood is medium-heavy 600-700 kg/cu. m when air seasoned; reasonably hard and durable. The heartwood is moderately resistant to termites. The wood saws easily and is used for interior construction, building of vehicle bodies, veneer production, furniture and wood carvings. It is advisable to treat surfaces with a grain filler before polishing. Wood also suitable for wooden houses.
Shade or shelter: A. ferruginea is a shade tree.
Medicine: In Ghana, plant parts are used to elicit purgation and treat dysentery. The bark decoction is used as a wash for wounds and sores.
Nitrogen fixing: Forms vesicular arbuscular mycorrhiza; highest mycorrhizal inoculation effect was observed at soil P concentration of 0.02 mg/litre. Based on these data, both Albizia and Enterolobium were classified as highly mycorrhizal dependent species. Nodulation is reported in A. ferruginea, Rhizobium-type root nodules are found on the roots.
Ornamental: A. ferruginea is a beautiful tree suitable for planting along avenues and in parks.
Soil improver: The tree’s leaf litter improves the quality of surrounding soil.
