Small or moderate tree to 15 m., the branchlets-strigose-puberulent and mark-edly lenticellate. Leaves moderately large, pinnate, 4-to 6-foliolate; petioles 2-4 cm. long, terete or nearly so, puberulent like the branchlets, swollen-callous basally; rachis similar to and (the internodes) about as long as or slightly longer than the petiole, wingless, bearing disc-like or subconic glands between insertions of *the petiolules (or these glands in part or entirely suppressed in some specimens); leaf-lets 2 or 3 pairs, elliptic to ovate, acuminate, those of the apical pair larger, up to 20 cm. long and 9 cm. wide, those of the lowermost pair usually about half as long and.broad, strigose-puberulent on both surfaces; stipules linear-lanceolate, 3-4 mm. long, caducous. Inflorescence an axillary, subterminal, paniculate or corymbi-form branch, the secondary spicate peduncles umbellate from the nodes, or some-times the spikes fasciculate or simple-umbellate directly from the axil; spikes short, the floriferous portion scarcely more than I cm. long, the many flowers densely congested. Flowers sessile, whitish; calyx subturbinate, 3-5 mm. long, the 5 teeth conspicuous but only about 0.5 mm. long, puberulent without; corolla tubular, somewhat expanded above the calyx, 7-9 mm. long, the lobes about 1 mm. long, pubescent without; stamens many, the filaments almost 2 cm. long in age, united into a tube for about I/2 their length, glabrous, the anthers minute, bilocular, only a fraction of a mm. long; ovary and style glabrous. Legume linear-oblong, about 13 cm. long and 2.5 cm. wide, slightly arcuate, lightly pubescent, flattened, some-what margined, apparently indehiscent.
More
A tree. It grows 6-15 m tall. The crown is broad and spreading. The trunk is straight and 30 cm across. The leaves have leaflets in 4 to 6 pairs. The leaflets at the end are larger. The leaf stalk does not have wings.
Found in moist forests from low elevations to the premontane zone. Dry, loamy soils in clearings, on forest margins and occasionally along steep, grass-covered hill slopes at elevations from 120-1,350 metres.
