Stems twining, terete, in dry state longitudinally wrinkled, sparsely appressed-pilose, greyish-brown. Leaves broadly to narrowly ovate, or oblong, 7-18 by 3½-13 cm, truncate or subcordate at the base, attenuate or acuminate at the apex, glabrous above, or with some scattered hairs, sparsely pilose with appressed hairs beneath; nerves 6-7 on either side of midrib; minor nervation reticulate with subparallel secondary veins; petiole 1.5-4(-8) cm, sparsely appressed-pilose. Peduncles axillary, slender, 7-20 cm, sparsely appressed-pilose, or more densely so towards the apex, cymosely branched at the apex, with many (rarely few) flowers in an umbellate cyme. Pedicels 1-2 mm, densely appressed-pubescent. Bracts lanceolate to narrowly oblong, obtuse, 3-7 mm long, appressed-pubescent outside, caducous. Sepals equal in length or outer ones a little shorter, ovate-oblong, obtuse, sometimes acutish, ca 5-6 mm long, densely greyish or whitish appressed-pilose outside; sepal 3 with one thin glabrous margin; two inner sepals with two thin glabrous margins. Corolla funnel-shaped, ca 2½-3 cm long, reddish; limb distinctly 5-lobed, ca 4 cm diam.; lobes ovate, midpetaline bands appressed-sericeous, their tips penicillate, tube and margins of lobes glabrous. Filaments glandular-papillose. Ovary glabrous, 2-celled. Fruit globose, ca 1 cm or slightly more in diam., purple or pinkish red; sepals slightly enlarged in fruit, inner ones with red margins; fruiting pedicels up to 8 mm, but often shorter; seed 1, globose.
Common in thickets and forests, especially along mountain streams at low and medium altitudes, ascending to 1500 m (Merrill).
