Ranunculus occidentalis, the western buttercup,[1] is a species of buttercup found in the western regions of North America. Its distribution extends from Alaska through British Columbia and Alberta to central California.[1] The flower can be seen in open meadows, forests, and other generally flat areas up to an elevation of 2,200 metres (7,200 ft).[2]
Aleut first nations may have used juice from the plant as a poison,[3] its toxicity arising from the substance protoanemonin.[4] Shasta first nations coincided blooming Ranunculus occidentalis with salmon runs in the summer.[5] The seeds were used to make pinole, a staple food.[6]
This plant is similar to, and sometimes difficult to distinguish from, the California buttercup (Ranunculus californicus).
