Morphology General Habit
Woody climber.
Morphology Branches
Branchlets rather densely covered with short golden-brown crisped hairs, sometimes also with longer spreading hairs intermixed, glabrescent.
Morphology Leaves
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.
Morphology Reproductive morphology Inflorescences
Panicles very similar to those of L. goetzei, but the variably developed indumentum golden-brown.
Morphology Reproductive morphology Flowers Calyx
Calyx 3.5–4.5 mm. long, with a golden-brown silky tomentum.
Morphology Reproductive morphology Flowers Corolla
Corolla ± 10–11 mm. long, white, sometimes marked or flushed rose-pink, ciliolate at petal-tips; wings a little shorter than keel.
Morphology Reproductive morphology Fruits
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.
Habitat
Lowland rain-forest, sometimes at the edges or riparian; 280–1050 m.
Distribution
T3 known only from the Usambara Mts.
