*Purple-leaved albizia, purple-leaved false thorn (En). *Muiando (Po).
== Origin and geographic distribution ==
Roots of ''Albizia antunesiana'' showed significant in-vitro activities against the tapeworm ''Hymenolepis diminuta'' (‘rat tapeworm’) and the trematode ''Schistosoma mansoni'', causal agent of schistosomiasis.
 
== Botany ==
 
Small to medium-sized deciduous tree up to 18(–25) m tall; bole usually short and branchless for up to 5 m but sometimes up to 12 m, straight or twisted, up to 75 cm in diameter; bark surface grey to brown, smooth or rough and reticulate, inner bark with reddish exudate; crown flattened, umbrella-shaped; young twigs glabrous or very shortly hairy. Leaves alternate, bipinnately compound with 1–3(–4) pairs of pinnae; stipules awl-shaped, caducous; petiole 4–8 cm long, grooved above, glabrous, near the base at upper side with a sessile gland, rachis 8–14 cm long, glabrous or sparsely pubescent; leaflets in (3–)4–8(–9) pairs per pinna, almost sessile, obliquely rhombic-ovate to elliptical-oblong, up to 5(–7) cm × 2.5(–4) cm, rounded to slightly notched at apex, glabrous, distinctly glaucous below. Inflorescence an axillary head on 2–11 cm long peduncle. Flowers bisexual, regular, 5-merous, greenish yellow; pedicel up to 2 mm long; calyx 3–5.5 mm long, with long tube toothed at apex, pubescent outside; corolla 5–11 mm long, pubescent outside; stamens numerous, 1.5–3 cm long, united at base, with white filaments; ovary superior, gradually tapering into an up to 3 cm long style. Fruit an oblong, flat pod 12–23 cm × 2.5–5 cm, almost glabrous, indistinctly transversely veined, pale brown when ripe, opening with 2 papery valves, c. 8-seeded. Seeds lens-shaped, 7–9 mm in diameter.
 
''Albizia antunesiana'' trees usually flower in August–November and fruits are ripe in April–September. The pod valves with seeds still attached are spread by wind.
 
''Albizia'' comprises about 120 species and occurs throughout the tropics. Approximately 35 species are found in continental Africa and about 30 in Madagascar. It is characterized by the head-like inflorescence, with 1–2 central flowers modified, functionally male and having a larger, nectar-producing staminal tube. Molecular analyses showed that ''Albizia'' is heterogeneous, and a revision of the genus is needed.
