This is a large, twining shrub, which can reach up to 10 m tall. The young stems are densely hairy but later hairless.

The leaves are arranged opposite, simple and entire, broadly ovate, measuring 7-18.5 cm x 5-13 cm, obtuse to truncate or subcordate at base, acuminate at apex, thinly leathery and pinnately veined. The petiole is 2.5-4.5 cm long, furrowed and hairless or hairy. The stipules are absent.

The inflorescence is an umbrella-shaped cyme, which is situated between the petioles of a leaf-pair and many-flowered. The peduncle is 2.5-7.5 cm long. The flowers are bisexual, regular and 5-merous. The pedicel is thin and up to 2.5 cm long. The sepal is on the inside, with 5 basal glands, 3 mm long segments and spreading. The petal is bell-shaped to rotate, 12-16 mm in diametre, bright green, hairless and with obtuse segments. The stamens are inserted at the base of the petal, with connate filaments, anthers with short apical membrane overarching the stigma and with solitary pollinium in each anther cell. The corona scales are about 4 mm in diametre which are inserted in staminal tube. There are 2 superior ovaries, free, 1-celled and with discoid stigma.
