Herbaceous perennial climber. Stems twining, up to 3.5 m long. Leaves large, broadly ovate-heart-shaped, narrowly pointed at the apex. Inflorescences, axillary, few to many-flowered.

South America, Mesoamerica, North America, Caribbean, Africa & Madagascar. Native to Mexico, Central America and tropical South America; introduced and naturalised elsewhere in the tropics
The seeds, vines, flowers, and leaves contain ergoline alkaloids, and have been used for centuries by many Mexican Native American cultures as an entheogen; they were known to the Aztecs as tlitliltzin, the Nahuatl word for "black" with a reverential suffix. In South America, the seeds are also known as "badoh negro".
