Coptis trifolia

Coptis trifolia (syn. Coptis groenlandica), the threeleaf goldthread or savoyane, is a perennial plant in the genus Coptis, a member of the Ranunculaceae family.

It has one small, deeply three-lobed, evergreen leaf rising from the ground.

The sepals are white and are easily mistaken for petals. The four to seven petals are yellow and club-like, and they are smaller than the stamens which are numerous and thread-like with delicate anthers.
