Nineleaf Biscuitroot
Lomatium triternatum
Carrot family (Apiaceae)

The peanut-sized roots are edible raw or cooked. Many animals including ground squirrels and other rodents feed on them. Biscuitroot was a staple of many Native American tribes. "Triternatum," means three times , i.e., leaves are split three times and then again three times and then again--although this species does sometimes split into threes only twice.
