Erythronium howellii
Also called Howell's Adder's Tongue, Howell's Fawn Lily
Howell's fawn lily is a small spring-flowering bulb native to the Klamath Mountains of southwestern Oregon and northwestern California, growing in serpentine soil in open woods. It is a wild woodland species rarely grown in gardens, so care notes are general guidance for a bulb of this type.
Erythronium howellii, or Howell's fawn lily, is a flowering plant in the lily family Liliaceae. It is endemic to the Klamath Mountains of southwestern Oregon and northwestern California. Taxonomic authorities are divided on whether E. howellii is a distinct species from the morphologically similar E. citrinum.
Erythronium howellii grows in sites with serpentine soil in open woods and along the edges of forests. The species was first collected in Josephine County, Oregon, where it grows from the southern end of the Illinois River Valley to the foothills of the Siskiyou Mountains, and its presence is well-documented there. There are also reports of E. howellii in Siskiyou, Trinity, and Del Norte Counties in northern California, but Elmer Applegate reported in his monograph of the genus that fieldwork suggested these populations were instead E. citrinum.
