This bisquitroot has lower leaves clustered near the base of the plant. Flowers small and yellow, grouped in umbels supported by unequal, slender pedicels 0.2-0.9 in (6-22 mm) long.

The species is found on rocky slopes and scablands, often in rocky swales saturated in the early spring.

This species is one of the many biscuitroots used as a food source by Native Americans.
