Caulophyllum thalictroides, the blue cohosh, is a species of flowering plant in the Berberidaceae (barberry) family. It is a medium-tall perennial with blue berry-like fruits and bluish-green foliage. The common name cohosh is probably from an Algonquian word meaning "rough".[citation needed] The Greek-derived genus name Caulophyllum signifies "stem-leaf", while the specific name thalictroides references the similarity between the large highly divided, multiple-compound leaves of meadow-rues (Thalictrum spp.) and those of blue cohosh.
