Argyreia cuneata is a perennial climbing shrub growing from 150–200 cm.

The leaves are about 6 centimeters long by 2.5 wide with wedge-shaped bases.

The seeds are brown, about 1 cm long, and elliptically shaped.

Like those of Argyreia nervosa, the seeds of A. cuneata contain various ergoline alkaloids such as chanoclavines and lysergic acid amides.
