Stems twining, up to 10 m high; young parts densely appressed-pilose with whitish or pale fulvous hairs, glabrescent, occasionally more or less farinose. Leaves elliptic to narrowly oblong, sometimes ovate or lanceolate, 4-15 by 1½-7 cm, base acute or attenuate into the petiole, or rounded; apex acute, shortly acuminate or obtuse, mucronulate, upper surface densely to sparsely appressed-hairy or glabrous, mostly with exception of the nerves; lower surface mostly densely sericeo-tomentose, with silvery white or pale fulvous hairs; nerves 9-18(-20) on either side of midrib; petiole 1-6 cm, appressed-pilose. Peduncle shorter to slightly longer than the petiole, ½-2½(-4½) cm, hairy, 1-5-, rarely more-flowered. Pedicels 5-15 mm, angular, hairy. Bracts obovate-oblong, obtuse, caducous. Sepals about equal in length, 2 outer ones broadly elliptic, obtuse, 8-10 mm long; sepal 3 and 4 elliptic to elliptic-oblong, obtuse to slightly emarginate; inner sepal oblong, slightly emarginate; all sepals densely sericeo-lanate outside, glabrous inside, in fruit enlarged, patent, red or purplish inside. Corolla funnel-shaped to campanulate, 5-6½ cm long, pale violet or pink with white base, or rarely entirely white; limb shallowly lobed; midpetaline bands with long, appressed hairs. Stamens and style much shorter than corolla; filaments pilose at the base. Ovary glabrous, 4-celled. Fruit subglobose, ca 8-10 mm diam., red or orange red, 4-or less-seeded. Seeds ca 5 mm long, black.

Uses. In Java a decoction of the root, along with Callicarpa, Anethum, and Alyxia is taken as a stomachic. The leaves serve as a poultice for boils, etc. The stems are sometimes used for tying purposes ( BURKILL A dictionary of the economic products of the Malay Peninsula 1935 HEYNE De Nuttige Planten ed. 2 1927 ).
