Glaucous lomatium is also known as Donnell's desert parsley. It is a fairly attractive perennial wildflower with its lacy leaves, glaucous herbage, and tufts of yellow flowers. The one to several stems are largely leafless and ascend from 15-30 cm high. The herbage is glabrous and highly bluish-glaucous. The short-petioled leaves are 5-10 cm long and are clustered near the base of the plant. The base of the petioles, especially on the higher leaves, is broadly expanded and sheathing on the scape, and may be reddish in color. The leaves are ternate-pinnately divided into numerous elliptic-oblong to wide, linear segments from 2-8 mm long. and from 1-2 mm wide (See photo below.)
The inflorescence consists of a complex umbel of 8-30 unequal stems, elongating from 1.5-9 cm long and topped by a small umbellet. The umbellets are subtended by distinctive bracts as seen at right. The pedicels are 4-12 mm long while the flowers are yellow. The fruit are elliptic or elliptic-ovate with the wings one-fifth to one-half as wide as the body. The fruit range from 5-10 mm long.
Glaucous desert parsley may be found on dry, open, rocky or gravelly slopes, ridgetops, and in dry meadows in the foothills, valleys, and lower mountains.
Glaucous desert parsley may be found in central and southeastern Oregon from northern Jefferson and southern Wasco Counties and southern Gilliam and Union Counties southeast to Harney and Malheur Counties.
