Circeæa

Circeæa, a small and unimportant but widely distributed genus of rather pretty little Onagraceous herbs. C. lutetiana, frequent in shady situations, bears the name of Enchanter's Nightshade, and in Germany Hexenkraut (Witches' Herb). The origin of these names is not easily explained, as the plant possesses no remarkable properties, being merely a little astringent.
