Description
Habit:
Stems twining, up to 5 m high, more or less densely and shortly appressed-pilose, later on glabrous.
Leaves:
Leaves ovate-oblong, ovate or elliptic,
6½-16 by 3½-10 cm, base rounded or slightly cordate, apex obtuse to acute; subcoriaceous, glabrous above, or with some hairs on midrib, more or less densely appressed-pilose beneath; midrib and 6-10 nerves on either side prominent beneath; petiole 2-10 cm, pilose like the stems.
Inflorescences:
Peduncles 5-20 cm, pilose like the stems, cymosely ramified at the apex, many-flowered. Pedicels 1-4 mm, in fruit up to 10 mm. Bracts minute, 1-2 mm long, caducous, rarely a casual foliaceous bract in the cyme.
Flowers:
Two outer sepals ovate-triangular, obtuse, 5 mm long, appressed-pilose outside or partly glabrescent, glabrous inside; sepal 3 orbicular or somewhat transverse-elliptic, 5-6 mm long, appressed-pilose with one glabrous margin, two inner sepals transverse-elliptic, strongly concave, 5- 6½ mm long, appressed-pilose with 2 glabrous
margins. Corolla deeply 5-lobed, pinkish purple; tube cylindrical, ca 6 mm long, glabrous, lobes linear or finear-lanceolate, reflexed, ca 16-18 mm long, appressed-sericeous outside, at the apex with 2 small glabrous lobules.

General comments:
The density of the indumentum ofstems, lower surface of leaves and inflorescences appears to be variable; itvaries from densely pilose or nearly tomentose to nearly glabrous.
