Panicles terminal and axillary (sometimes the latter reduced and few-flowered), up to 18–60 cm. long, with usually numerous ascending branches; axes brown pubescent to velutinous; fascicles of mature panicles not very crowded; bracts subtending fascicles and flowers linear-lanceolate to ovate, 1–2 mm. long. Calyx 2.5–4 mm. long, brownish tomentellous. Corolla 7–9(–12) mm. long, cream or white, sometimes with small scattered hairs mostly on the keel and wings; wings as long as the keel. Fruit linear-oblong or oblong, not winged, rounded at the ends, subsessile, 6–10 cm. long, 1.8–3 cm. wide, papery, densely appressed pubescent, ultimately glabrescent, laxly venose, 1–2-seeded.
