Pediomelum cuspidatum (also known as Psoralea cuspidata) is a perennial herb also known as the buffalo pea, largebract Indian breadroot and the tall-bread scurf-pea.

It has an inflorescence on stems 18-40 centimeters long arising from a subterranean stem and deep carrot-shaped root that is 4–15 cm long.

The flowers, borne in condensed spikes from the leaves, are light blue and pea-like.

Pediomelum cuspidata emerges in late Spring, and sets few seeds, unlike its smaller, fecund cousin Pediomelum hypogaeum.

The species has edible tuberous roots, although some sources describe it as 'bitter'.
