Stems twining, densely appressed-pilose to tomentose, with fulvous hairs. Leaves narrowly ovate or ovate, 8-17 by 3½-9 cm, rounded at the base, attenuate towards the acute or acuminate apex; lower surface densely appressed-pilose with straight or slightly curved hairs, or almost tomentose in youth, upper surface less densely hairy with more rigid hairs; midrib and 8-10 nerves on either side distinctly visible on both sides; petiole 3-8 cm, grooved, pilose like the stem. Peduncles axillary, terete, rather slender, 4-10 cm, densely pilose; flowers in a small, dense, more or less capitate cyme; branches of cyme very short. Pedicels 2-4 mm. Bracts subpersistent, broadly obovate, rounded to truncate at the apex, ca 10-12 mm long, densely appressed-pilose outside, glabrous inside. Sepals concave, elliptic-oblong, obtuse; two outer ones ca 8 mm long, outside pilose like the bracts, inside glabrous; sepal 3 slightly oblique, ca 1 mm long, outside pilose with one glabrous margin; two inner sepals ca 6½ mm long, nearly glabrous. Corolla deeply 5-fid, pink, the lobes with white tips; tube ca 5 mm long, glabrous; lobes linear, ca 11 mm long, densely hairy outside, with 2 glabrous lobules at the apex. Filaments inserted at the mouth of the tube, glabrous. Ovary glabrous, 2-celled. Fruit ellipsoid, 10-12 mm long, red (MUKMJN AMIR in herb. Sandakan, n. 35633).
