孔药花属

Description from Flora of China

Herbs perennial, climbing. Rhizomes absent. Stems long, branched, climbing, basally woody. Leaves alternate. Inflorescences borne near apex of branches, penetrating leaf sheaths, each a sessile head usually with several flowers. Flowers actinomorphic. Sepals free, imbricate, carinate. Petals free, pink, green, or white, elliptic or oblong. Stamens 6, all fertile, subequal; filaments lanate; anther locules oblong or deltoid-ovoid, connate for most of their length, dehiscent by apical pores. Ovary 3-loculed; ovules 2 per locule. Capsule 3-valved, ellipsoid or ovoid-globose, trigonous. Seeds 2 per valve, cylindric, trigonous, rugose, reticulate; hilum linear.

Porandra is similar and related to Amischotolype from which it differs in having stems long, branched, climbing, and basally woody, and anther locules dehiscent by apical pores rather than longitudinal slits.

Three species: China, Laos, Thailand, Vietnam; three species (two endemic) in China.
