Erythronium tuolumnense is a species of flowering plant in the family Liliaceae, known by the common name Tuolumne fawn lily or Tuolumne dog's tooth violet. However, it is neither a true lily nor a violet. It is endemic to the Sierra Nevada of Tuolumne County, California; from Шаблон:Convert along Italian Bar Road up to Шаблон:Convert altitude at the headwaters of Deer Creek.[1]

This hardy perennial wildflower grows from a bulb Шаблон:Convert wide, sometimes with associated bulblets. The bulb resembles a dog's tooth in shape and colour, hence the name "dog's tooth" (which also applies to other erythronium species such as E. dens-canis). It produces two small leaves and a reddish stalk up to Шаблон:Convert tall bearing one to five flowers. The flower has bright yellow recurved tepals, a white style and white stamens tipped with large yellow anthers.[1][2][3]

This rare plant is threatened by human activity such as logging in its small native range.

Inhabiting moist, light deciduous woodland, this plant is also found in cultivation. The species[4] and the hybrid cultivar 'Pagoda'[5] have gained the Royal Horticultural Society's Award of Garden Merit.

Conservation

Known from only a small number of populations, the largest of which have over ten thousand individuals. Erythronium tuolumnense is listed as imperiled by NaturServe. It has a small historic range, and human activity, especially recreational off-road vehicle use threatens the largest population. Other threats include mining, garbage dumping, camping, logging and fire suppression.[6]
