Century Dictionary and Cyclopedia
npicrisA genus of composite plants, of the tribe Cichoriaceæ and subtribe Crepideæ, distinguished by its plumose pappus. There are about 25 species, in Europe, northern Africa, and temperate regions of Asia; one, P. hieracioides, the German biiterkraut, is also widely diffused throughout the northern hemisphere. All are erect, branching, bristly, and rough, with many alternate coarsely cut or entire leaves and bright-yellow flowers. Several species are cultivated for the flowers. P. echioides (often called Helminthia) is the British wayside weed oxtongue, so called from the shape of its leaves.
