Cynanchum amplexicaule, a
perennial of 40-130cm in height, grows in grasslands or around
wetlands. Of opposite phyllotaxis, leaves are white-green, in the
shape of an oblong with bases ear-shaped, embracing the stems. Axils
emerge branching peduncles with many flowers; yellow-tinged corollas
cleft themselves in five, and the lobes are oblong-ovate-like
triangular, around 3mm in length. July-August.
