Pediomelum

Pediomelum is a genus of legumes known as Indian breadroots. These are glandular perennial plants with palmately-arranged leaves. They have a main erect stem with inflorescences of blue or purple flowers and produce hairy legume pods containing beanlike seeds. Some species have woody roots while others have starchy tuber-like roots which can be eaten like tuber vegetables such as potatoes or made into flour. Indian breadroots are native to North America. Many species have synonymy with genus Psoralea.
