Cynanchum is a

succulent climbers or twiners. There is some evidence of toxicity.[2]

Morphology

These plants are perennial herbs or subshrubs, often growing from rhizomes. The leaves are usually oppositely arranged and sometimes are borne on petioles. The inflorescences and flowers come in a variety of shapes.

Like other species of the milkweed family, these plants bear follicles, which are podlike dry fruits.

Distribution

These species are found throughout the

temperate
regions.

Importance

The root of

Chinese traditional medicine
and called Bai wei. Several other species had traditional Chinese medicinal uses.

Classification

Cynanchum as defined in the late 20th century (to include about 400 species) is

Pentarrhinum, and Vincetoxicum, with a group of mostly Old World species staying in Cynanchum,[3][4] and old genera such as Raphistemma brought to synonymy. Revision of the genus taxonomy in 2023 identified two new synonyms: Vincetoxicum sibiricum f. linearifolium, described from Shandong, China in 1877, but long neglected and Cynanchum gobicum, previously believed to be endemic to Mongolia.[5]

Species

As of February 2023[update], Plants of the World Online accepted the following species:[6]
