Fritillaria eastwoodiae, also known as Butte County Fritillary or Eastwood's Fritillary is a rare member of the Lily family (Liliaceae), endemic to the foothills of the northern Sierra Nevada, and Cascade Mountains in California. It grows in dry open woodlands and chaparral from 500 to 1500 meters, in Shasta, Yuba, Tehama, Butte and El Dorado Counties. It occurs in similar habitat with F. affinis, F. micrantha, and F. recurva, and blooms from March through May. It can sometimes be found on serpentine soils. It grows to heights from 20 to 80 centimeters, and has linear to narrowly lance-shaped leaves arranged on its waxy pale stem. Its flowers are nodding with slightly flared and slightly recurved petals. Its color varies from greenish-yellow mottled to a mixture of red, orange, green and yellow mottling.
