Liana or more or less scandent to erect shrub. Branches densely ferruginous-tomentose, more or less glabrescent. Leaves 2-5-jugate, the petiole, rhachis, and petiolules densely rusty tomentose when young; petiolules 0.25-0.5 cm. Leaflets lanceolate (the terminal ones oblanceolate) to oblong, 4-15 by 1-5.5 cm, thin-chartaceous to subcoria-ceous, when young ferruginous-tomentose on both sides, especially beneath; base usually subpeltate, of the lateral leaflets rounded to slightly cordate rarely cuneate, of the terminal ones cuneate; apex gradually, sometimes very shortly blunt-acuminate; nerves 5-6(-9) pairs, ascending, curved (rarely nearly straight), looped and more or less distinctly joined near the margin. Inflorescences 20-35 cm long, densely ferruginous-tomentose, the branches transverse, up to 15 cm long, many-flowered. Bracts minute and scale-like to subulate, up to 1 cm long, and recurved. Sepals oblong-ovate, 3.5 by 1.5 mm, complicate, keeled, outside densely brown-tomentose, inside glabrous. Petals linear to elliptic, blunt, 5½-8 mm long, rather densely (rarely outside sparsely) appressed-pubes-cent on both sides, inside with many glandular hairs, brownish to white, punctate. Stamens for c. 0.75 mm connate, epipetalous ones probably not always fertile, all filaments slightly glandular-pubescent, especially the episepalous ones in the upper part. Fruits oblique-ellipsoid, compressed, c. 2.5 by l.5 cm, stipe very short, beak minute, nearly terminal, pericarp thin, outside obliquely minutely wrinkled, ferruginous-tomentose, glabrescent, inside subglabrous.
On dry, open slopes, in dry thickets, and in forests, at low altitude.
