Slender, twining. Ultimate twigs short-hairy, mixed with capitate-glandular hairs, internodes soon glabrate, shiny-brown, rather long. Leaves ovate to obovate, or ovate-oblong, base truncate, rounded or cordate, apex acute to acuminate, upperside glabrous or the base of the midrib hairy, beneath glaucous, short-pubescent, 4-11 by 2-6½ cm; petiole ½-1 cm, pubescent. Inflorescences short-grey-hairy, mixed with distinctly stalked capitate-glandular hairs, terminal and in the upper axils so as to form a rather lax, leafy panicle, exceeding the leaves; lower branches up to 6 cm, with reduced leaves, upper internodes not abbreviated. Flowers creamy, fragrant, later fading into yellowish. Bracts linear-lanceolate, as long as or longer than the calyx. Bracteoles ovate, shorter than the ovary. Calyx purplish, lobes lanceolate, 1½-2 mm, the lobes mostly rather densely grey-hairy, sometimes only ciliate. Bud club-shaped, thickened end ± ⅓-¼ of the mature bud, often acute. Corolla 18-30 mm (fresh 3-3½ cm) long, the tube slender, 1 mm or thinner, 1-2 cm, lobes narrow, 8—14 mm long, ± 1-2⅓ mm broad, during anthesis both lips recurved, lobes as long as the tube or shorter; hairs on the corolla recurved, except the capitate glandular ones. Anthers thin, 2-4 by ⅓-½ mm. Stamens protruding, glabrous. Style often longer than the corolla, glabrous, exserted. Berry dark purple, ripe prob. black.
