Seldom exceeding 30 cm dbh.
Leaflet blades rather large, about 12-24 x 4-9 cm, with a short stalk. Petiole swollen at its junction with the compound leaf rhachis. Midrib raised on the upper surface of the leaflet blades. Lateral veins forming loops just inside the blade margin.
Panicles about 20-34 cm long, densely flowered, pedicels about 2-5 mm long. Calyx lobes about 1.5-4 mm long. Petals about 2.5 mm long, clawed, with thickened basal margins, pubescent outside. Stamens usually eight, filaments about 4-5 mm long, densely hairy over most of the filament. Disk glabrous, orange (?), stamens inserted inside the disk.
