Tuolumne fawn lily

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 600 m (1,969 ft) along Italian Bar Road up to 1,000 m (3,281 ft) altitude at the headwaters of Deer Creek.

This hardy perennial wildflower grows from a bulb 5–10 cm (2–4 in) 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 35 cm (14 in) tall bearing one to five flowers. The flower has bright yellow recurved tepals, a white style and white stamens tipped with large yellow anthers.
