Butterwort

 

(Pinguicula), a genus of perennial insectivorous plants of the family Lentibulariaceae. The leaves are in a basal rosette and are usually elliptical. They are covered by glandular hairs which secrete a mucilage that traps small insects and a sap containing proteolytic enzymes that dissolve the proteins in the insects’ bodies. The flowers are solitary and located on long peduncles. The corolla is bilabiate and spurred. It is violet, blue, or pink, rarely white. There are two stamens. The fruit is a capsule. There are about 35 species in the extratropical regions of the northern hemisphere and in South America. In the USSR there are six or seven species, primarily in the north. The common butterwort (P. vulgaris), which grows in damp places, is the most widely distributed.
