*''Albizia sassa'' (Willd.) Chiov. (1912).

*Peacock flower, smooth-bark flat-crown (En). *Farroba de Lala, mpepe (Po). *Mkenge, mchapia tumbili, mchani mbao, mshai (Sw).

*Medium-sized deciduous tree up to 30 m tall; bole straight and cylindrical, up to 75(–100) cm in diameter, without buttresses or with small, thick buttresses; bark yellowish to grey, usually smooth, inner bark with clear gum; crown flattened; young branches finely pubescent, but soon glabrescent. *Leaves alternate, bipinnately compound with (3–)5–7(–8) pairs of pinnae; stipules lanceolate, up to 7 mm long, caducous; petiole 2.5–4.5 cm long, near the base of upper side with a sessile gland, rachis 4.5–11 cm long, pubescent; leaflets in 6–17 pairs per pinna, sessile, obliquely rhombic, up to 2 cm × 1 cm, often auricled at proximal side of base, obtuse to acute at apex, glabrous but with some hairs on midrib and margins. *Inflorescence an axillary head on a 2.5–5 cm long peduncle. *Flowers bisexual, regular, 5-merous, reddish white, almost sessile, subtended by up to 6 mm long, caducous bracteoles; calyx obconical, 2–5 mm long, minutely pubescent outside; corolla 7–12 mm long, with 4.5–6 mm long tube, pubescent outside; stamens numerous, 2.5–3.5 cm long, united into a tube for most of their length, white in lower part and reddish in upper part; ovary superior, ellipsoid, 1.5–2.5 mm long, gradually tapering into a 2.5–3.5 cm long style. *Fruit an oblong, flat pod 10–21 cm × 2–4 cm, with stipe c. 1 cm long, glabrous, transversely veined, pale brown to reddish brown when ripe, opening with 2 papery valves, 9–12-seeded. *Seeds flattened globose to broadly oblong, 8–12 mm × 7–10 mm.

=== ''Albizia grandibracteata'' ===''[[Albizia grandibracteata]]'' Taub. is another closely related species. Like that of ''Albizia gummifera'', its wood is known under the trade name ‘red nongo’. It differs from ''Albizia gummifera'' in having fewer leaflets per pinna (as in ''Albizia zygia'') and broad bracts and stipules. Hybrids between ''Albizia gummifera'' and ''Albizia grandibracteata'' have been recorded. ''Albizia grandibracteata'' occurs in eastern DR Congo, Rwanda, Burundi, southern Sudan, south-western Ethiopia, western Kenya, Uganda and northern Tanzania. Its wood is similar to that of ''Albizia gummifera'' and used for the same purposes. It is also used as firewood and for charcoal production. In DR Congo a leaf infusion, together with other ingredients, is used in a vapour bath to treat fever, in Uganda the pounded leaf is taken mixed with other ingredients to treat diarrhoea, and in Kenya a root infusion is drunk to treat tonsillitis. A methanolic extract of leaves of ''Albizia grandibracteata'' and saponins isolated from this extract have shown in-vitro antitumour activity against KB and MCF7 cell lines. Like ''Albizia gummifera'', ''Albizia grandibracteata'' is planted as an ornamental and shade tree, and to improve the soil.

=== ''Albizia viridis'' ===''[[Albizia viridis]]'' E.Fourn., a tree up to 20 m tall from Madagascar, may be confused with ''Albizia gummifera'' because of its obliquely rhombic leaflets, but it differs in having stipels at the base of pinnae and stamens united at base in a much shorter tube. In northern and eastern Madagascar the wood of ''Albizia viridis'' is used for flooring and furniture.  === ''Albizia mahalao'' ===''[[Albizia mahalao]]'' Capuron is close to ''Albizia viridis'', but has oblong to elliptical leaflets (not rhombic). It is a small tree up to 10(–15) m tall, rather frequent on sandy soils in southern Madagascar. Its wood is used for construction.  === ''Albizia mainaea'' ===''[[Albizia mainaea]]'' Villiers is a small tree up to 15 m tall with a bole diameter up to 60 cm, widespread in western and southern Madagascar. It resembles ''Albizia gummifera'', but can be distinguished by its grooved leaf rachis, almost completely glabrous leaflets and pubescent pods. Its wood is brown and hard and used for construction and canoes.
