Pentastelma Tsiang et P. T. Li

白水藤属

Description from Flora of China

Lianas. Leaves opposite, petiolate. Cymes axillary. Flower buds ovoid, apex acute. Calyx with basal glands. Corolla subcampanulate; lobes longer than tube, overlapping to right. Corona lobes 5, adnate to gynostegium, fleshy, with lateral vertical processes. Filaments connate into a tube; anthers appressed against stigma, apical appendages incurved; pollinia 2 per pollinarium. Stigma head discoid, apex slightly convex.

One species: endemic to China.

The protologue describes the pollinia as pendulous, but Pentastelma otherwise shows many similarities to Tylophora, suggesting that the anther morphology needs reexamination.
