Lomatium bradshawii
Lomatium bradshawii, also known as Bradshaw's desert parsley, is an endangered perennial herb native to Oregon and Washington, United States. Lomatium bradshawii was thought to be extinct until 1979, when it was rediscovered by a University of Oregon graduate. This herb was common in the Willamette Valley before agricultural development and fire prevention which has allowed shrubs and weeds to invade. Most known populations of Lomatium bradshawii are within ten miles of Eugene, Oregon. In the Willamette Valley, populations exist in the Oregon counties Lane, Benton, Linn, and Marion, and in Washington Lomatium bradshawii grows in Puget Sound.
