Large climbers; young branchlets brown tomentose, glabrous at maturity. Leaves broadly elliptic, almost rounded at the base, obtuse or abruptly and shortly acuminate at apex, 18 - 22 x 6 - 11 cm, glabrous above, except the tomentose sunken midrib; petioles 1 - 1.5 cm long, stout, tomentose. Flowers solitary or 3 - 5 together in leaf-opposed or terminal cymes; peduncles ca 5 mm long; pedicels 1.5 - 2 cm long, brown pubescent; bracts basal, median, minute, ovate, pubescent. Sepals 3, broadly triangular, slightly outside at base, acute, 2 - 3 x 3 - 4 mm, pubescent outside, glabrous inside. Petals 6 (3 + 3); outer ones narrowly oblong to lanceolate, acuminate, 2.5 - 3 x ca 1 cm, brown tomentose outside, pale pink and hoary inside; inner ones shorter and narrower, with triquetrous limb, pubescent outside, glabrous and yellowish inside. Stamens many, ca 2.5 mm long, pink; connectives slightly oblique and apiculate at top. Carpels many, ca 2 mm long, strigose; style stout; stigma obtuse, grooved. Ripe carpels many, globose or oblong, obtuse or slightly apiculate at apex, ca 1.5 cm in diam., pubescent, thin-walled; stalk 1.5 - 2 cm long, pubescent. Seeds several in 2 rows, dark shiny brown .
