Fritillaria pudica, the yellow fritillary, is a small perennial plant found in the sagebrush country in the western United States and Canada. It is a member of the lily family Liliaceae. Another common name is "yellow bells", since it has a bell-shaped yellow flower. It may be found in dryish, loose soil; it is amongst the first plants to flower after the snow melts, but the flower does not last very long; as the petals age, they turn a brick-red colour and begin to curl outward. The flowers grow singly or in pairs on the stems, and the floral parts grow in multiples of threes. The species produces a small bulb, which forms bulblets earning the genus the nickname 'riceroot'. During his historic journey, Meriwether Lewis collected a specimen while passing through Idaho in 1806.
