P. maculatus is a trailing perennial herb with a large, woody taproot. Leaves are trifoliate, oval, up to 8 cm (3.2 in) long, with small uncinate (hooked) hairs. Leaf blades tend to be oriented vertically so they do are not pressed against the ground. Flowers are purple. Seeds are mottled black and brown.[5][6][7]
Uses
This bean is often used as livestock forage, and it is cited as a gene source for disease resistance in the lima bean (P. lunatus) by Germplasm Resources Information Network. The Tarahumara peoples of the Sierra Madre Occidental in Chihuahua use the roots medicinally and also make glue from the shoots.[8] The species is also occasionally grown as an ornamental.[9]
