Dentaria or coral-root is a genus of plants of the natural order Cruciferae. There are about twenty species, natives of temperate countries. They are ornamental herbs, with creeping singularly toothed root-stocks, from which they receive the names of coral-root and tooth-wort. The stem-leaves are opposite or in whorls of three, and the flowers are large and purple. Dentaria bulbifera, the only British species, is a rare plant in the south-east of England. Dentaria diphylla, or pepperwort, a North American species, has roots that are used as mustard. Research Dentaria
