Leaflets 3–12 × 0.6–3 cm, lanceolate, narrowly elliptic or oblong, acute to rounded at the apex but mucronate, cuneate to rounded at the base, glabrescent to densely pilose; petiole winged, or sometimes in upper leaves unwinged, 3–20 × 2–7 mm, linear, linear-oblong or oblanceolate, mostly shallowly to deeply emarginate at the apex; stipules 5–8 × 0.7–1.5 mm, linear to lanceolate. Inflorescences terminal, simple, falsely racemose, 10–35 cm long, sometimes with axillary ones as well or a few flowers in the axils, pubescent to appressed pilose. Flowers as in D. pteropus. Calyx glabrescent to pilose with spreading white hairs.
