Description

Phyllodium pulchellum is a shrub that can grow up to 2.5 m tall. Its branch­es are slender, cylindrical and pubescent.

The leaves are 3-foliolate, with petiole 6-10 mm long, narrowly triangu­lar stipules, measuring 6-8 mm x 2-3 mm, with rachis 10-20 mm long, with ovate ter­minal leaflet, elliptical or obovate and measures (2.5-)6-9 (-17) cm x (1.5-)3-5(-7) cm. The leaf base is obtuse or rounded, emarginate to acuminate at apex and with shallowly undulate margin. The lateral leaflets are similar, measure (1-)3-5(-8) cm x (1-)2-3(-5) cm and asymmetri­cal at base.

The raceme is 7-55 cm long, and composed of 5-6-flow­ered fascicles. The lateral leaflets of bracts are orbicular. They measure 8-15 mm x 7-13 mm. The petal is white or pale yellow, standard obovate, measures 5-6 mm x 3-4 mm and with 6-7 mm long pistil.

The pods are oblong, measure 7-8(-12) mm x 3-5 mm, sparsely hairy, reticulate-veined and (1-)2(-3)-arti­cled. The articles are 3-4 mm long, suborbicular or quadrangular.

The seed is transversely elliptical or suborbicu­lar, and measures 2 mm x 2.2-2.8 mm.

Ecology / Cultivation

Phyllodium pulchellum is found in teak forests, thickets, dry grassy fields, and sometimes along watercourses up to 900(-1600) m altitude.
