Hamblen's Desert Parsley, Hamblen's Biscuitroot, Hamblen's Desert-parsley: Lomatium farinosum var. hambleniae (Synonym: Lomatium hambleniae)

Hamblen's desert parsley is a perennial wildflower up to 50 cm high. The herbage is generally glabrous. The dissected leaves are found at the base of the plant atop a globose-thickened taproot from 1-2 cm thick. The leaves are ternately to ternate-pinnately compound and divide 1-3 times into long, narrow segments from 1-10 cm long and 0.5-3 mm wide. One to several scapes are curved-ascending from 15-50 cm long at maturity.

The rays of the compound umbels are unequally elongate, with the longer ones ranging from 3-7 cm long at maturity. The few bracts below the individual umbels are 1-3 mm long at flowering and up to 5 mm at maturity. The flowers are yellow. The slender pedicels range from 6-22 mm long at maturity. The fruits are glabrous and elliptic in shape, ranging from 5-6.5 mm long and up to half as wide. The narrow wings range from 1/3 to 1/2 the width of the body of the fruit.

Hamblen's desert parsley may be found on rocky ground and in scablands in the foothills and valleys.

Hamblen's desert parsley may be found in north-central Oregon on both sides of the Deschutes River while in Washington it is found on both sides of the Columbia River from central Washington north to northern Washington.

The photo at left shows a close-up of the individual involucels which make up the umbel of Hamblen's desert parsley. Note the narrow bracts beneath each involucel. These bracts of this species tend to be offset to one side of the involucel as seen here.
