A large spreading tree up to 24 m tall. It has a broad dense evergreen crown. In dry areas the tree can lose its leaves. The trunk can be 1 m across. The bark is rough and grey with a checkered pattern. The leaves are carried one after another along the branch. The whole leaf is 6-12 cm long and it is divided into 10-17 pairs of leaflets. These are oblong and without stalks. The whole leaf has a leaf stalk about 15 cm long. The leaflets are 1-2.5 cm long and 4 9 mm wide. They are a dull dark green and with a rounded tip. The flowers are pale yellow with brown markings. The flowers are about 2.5 cm across and hang on long many flowered stalks. The fruit is an oblong thin skinned fleshy capsule. The brown seeds are inside this long rough surfaced, sausage-like fruit. This pod is 6-8 cm long and about 2 cm wide and contracted between the seeds. The pod cracks when mature. It is a legume. The pulp is date like and reddish brown. The seeds are shiny and hard. The pulp of the pods is edible.
Trees, 10-15(-25) m tall. Trunk 30-50(-90) cm d.b.h. Bark dark ashy, irregularly longitudinally splitting. Leaflets oblong, small, 1.3-2.8 cm × 5-9 mm, glabrous, base obliquely rounded, apex rounded or emarginate. Flowers few, yellowish tinged with purplish red stripes; peduncles and pedicels yellowish green puberulent; bracteoles 2, ca. 1 cm, enclosing flower bud before anthesis. Calyx tube ca. 7 mm; lobes lanceolate-oblong, ca. 1.2 cm, reflexed after anthesis. Petals obovate, subequal to calyx lobes, margin repand, curled. Stamens 1.2-1.5 cm, pubescent near base, free parts of filaments ca. 7 mm; anthers elliptic, ca. 2.5 mm. Ovary slightly incurved, terete, ca. 8 mm, hairy. Legume brownish, straight or arcuate, terete-oblong, turgid, 5-14 cm, often irregularly constricted. Seeds 3-14, brownish, shiny. Fl. May-Aug, fr. Dec-May. 2n = 24, 26, 28*.
Tree to 20 m tall. Leaves: petiole 4-8 mm long; rachis 4.5-12 cm long; leaflets in 10-18 pairs, oblong, 0.8-2.5 cm long, 3-10 mm wide, mostly rounded to rounded-subtruncate apically, glabrous throughout or with a basal tuft of hairs on lower surface, or sometimes pubescent on midrib and margins or throughout; venation conspicuous. Racemes 1-15 cm long. Flowers red in bud. Hypanthium 3-5 mm long. Sepals 8-12 mm long, pubescent basally within. Petals: upper larger three 10-13 mm long, elliptic or obovate-elliptic, yellow with red veins. Pod subcylindric, curved or straight, mostly 6.5-14 cm long, 1.5-3 cm in diam., closely covered with small, brown scales; margins sometimes irregularly constricted.
