== Vernacular names ==

== Origin and geographic distribution ==

''Albizia arenicola'' is endemic to Madagascar, where it is widespread in the western part of the island.

== Uses ==

The durable wood is used for poles in house construction.

== Botany ==

Small to medium-sized deciduous tree up to 15 m tall; bark grey, usually smooth, inner bark fibrous, with sticky gum; young branches sparsely pubescent, glabrescent. Leaves alternate, bipinnately compound with 4–9 pairs of pinnae; stipules minute, caducous; petiole 1.5–2.5 cm long, in the basal half of upper side with a sessile gland, rachis 3.5–5.5 cm long, pubescent; leaflets in (2–)4–17 pairs per pinna, sessile, obliquely oblong to obovate-oblong, up to 8 mm × 4 mm, rounded at apex, pubescent on both sides. Inflorescence an axillary head on 2–4 cm long peduncle. Flowers bisexual, regular, 5-merous, greenish white, almost sessile; calyx narrowly obconical, 1.5–2 mm long, glabrous; corolla 5–6 mm long, glabrous; stamens numerous, (1.5–)2–2.5 cm long, united into a tube at base, white; ovary superior, shortly stipitate, glabrous, gradually tapering into a 2–2.5 cm long style. Fruit an oblong to broadly oblong pod 7.5–16 cm × 2.5–6 cm, with short stipe, slightly swollen, with thick and woody fruit wall, glabrous, without veins, several-seeded. Seeds ellipsoid, 10–16 mm × 4.5–8 mm, black.

''Albizia arenicola'' flowers from August to November. The flowers are pollinated by insects such as butterflies.

== Description ==

== Other botanical information ==

== Growth and development ==

== Ecology ==

''Albizia arenicola'' occurs widespread but scattered in dry deciduous woodland and scrubland up to 700 m altitude, on sandy soils and sandstone.

== Propagation and planting ==

== Genetic resources ==

There are no indications that ''Albizia arenicola'' is threatened by genetic erosion.

== Prospects ==

It is unlikely that the utilization of ''Albizia arenicola'' timber will increase beyond its current local importance.
