There are about 8 species, widely scattered through temperate regions. They are low plants, often supporting themselves by hooks which terminate long hairs, and bearing small al ternate three-nerved leaves and little bracted flowers. They are known as pellitory or paritory; also hammer wort, and formerly helxine. P. officinal is, the most common species, is the wall-pellitory or lichwort. See pell i tory.
