The western buttercup (ranunculus occidentalis) is a species of buttercup found in the western United States and Canada. The flower can be seen in open meadows, forests, and other generally flat areas up to an elevation of 2,200 meters (7,200 feet). Aleut Indians may have used protoanemonin, a substance produced when the plant is handled or damaged as a poison, while Shasta Indians coincided blooming R. occidentalis with salmon runs in the summer.
