Great Basin Desert Parsley

Lomatium simplex var. simplex

Nine-leaf desert parsley is a perennial wildflower with one to a few erect stems arising from 20-80 cm high from a narrowly thickened, elongate taproot. The herbage is covered with fine, short but stiff hairs. The leaves are mostly basal, although some may be present at the middle or upper parts of the stems. The leaves are ternately or ternate-pinnately compound 2-3 times, and cleft into long, narrow segments or leaflets from 1-10 cm long.

The inflorescence is an umbel with 6-18 branches of unequal length supporting the umbellets, these stems measuring up to 2-10 cm long. The flowers are yellow. The fruits are broadly elliptic with broad wings about as wide as the body of the fruit. The fruits measure from 7-15 mm long and 3-7 mm wide. The bracts below the umbelets are inconspcuous, filiform in shape when present, or are absent.
