The plant is called skunk cabbage because of the distinctive "skunky" odor that it emits when it blooms. This odor will permeate the area where the plant grows, and can be detected even in old, dried specimens. The distinctive odor attracts its pollinators, scavenging flies and

Ranunculus occidentalis, the western buttercup, 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. 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).
