[Wikipedia] Distribution, Reclassification: Erythronium howellii, or Howell's fawn lily, is a flowering bulb in the lily family endemic to northwestern California and southwestern Oregon.[2][3] It has been reclassified by the Jepson Manual as Erythronium citrinum var. citrinum.[4][5] Distribution It is found in the Klamath Mountains and northern Outer California Coast Ranges.[2] There are small populations in Siskiyou, Trinity, and Del Norte Counties in northern California; and in Curry, Josephine, and Jackson Counties in Oregon.[2][6][7] It is listed as vulnerable for the following reasons: "Range is Del Norte Co., Calif., and adjacent southern Oregon. Most of the populations occur in Oregon, a few in California. Oregon sites number <38. Populations are not large, many reported during pre-timber harvest surveys."[8] (link added by Mary Ann Machi)
