Woody climber.. Branchlets rather densely covered with short golden-brown crisped hairs, sometimes also with longer spreading hairs intermixed, glabrescent.. Leaves 14–38 cm. long; stipules ovate, 5–6 mm. long; rhachis prolonged 1–3.5 cm. beyond the distal pair of leaflets; stipels 1–3 mm. long; lateral leaflets in 2(–3) pairs, elliptic-oblong to oblong-obovate, 7–15 cm. long, 5–9.5 cm. wide, rounded to emarginate (but sometimes acuminate on sucker leaves) with a fragile 2–3 mm. long mucro, narrowed to the broadly cuneate, rounded or cordate base, asymmetric, chartaceous to coriaceous, glabrescent above except sometimes for a short tomentum on the impressed nerves, usually golden-brown spreading pubescent beneath but varying from thinly and inconspicuously puberulous to densely velutinous; primary lateral nerves ascending, 6–9 on either side, prominent; venation ± reticulate but with the oblique veins rather more strongly developed, prominent or covered by the indumentum.. Panicles very similar to those of L. goetzei, but the variably developed indumentum golden-brown.. Calyx 3.5–4.5 mm. long, with a golden-brown silky tomentum.. Corolla ± 10–11 mm. long, white, sometimes marked or flushed rose-pink, ciliolate at petal-tips; wings a little shorter than keel.. Young fruit oblong, pointed at either end, shortly stipitate, narrowly winged along the upper edge, up to 7 cm. long and 2 cm. wide, papery, pubescent, venose, 1-seeded; mature fruit not seen.
