FUMARIA, in botany, a genus of the diadelphia hexandria class. The calix consists of two leaves; and the corolla is ringent. There are 11 species, three of them natives of Britain, viz. the officinalis, or fumitory; the capreolata, or ramping fumitory; and the claviculata, or climbing fumitory.
The whole plant of the officinalis is used in medicine, being accounted good in the scurvy, jaundice, and disorders of the mesentery and spleen.
