(Lysimachia), a genus of herbaceous plants, predominantly perennials, of the family Primulaceae. There are approximately 150 species (by other data, up to 200), mainly in the temperate regions almost everywhere on the terrestrial globe, especially in Eastern Asia and North America. In the USSR there are more than ten species. Most frequently found (in moist places) are the common loosestrife (L. vulgaris), a tall plant, up to 1.25 m high, with yellow flowers in paniculate racemes; and the moneywort, so-called meadow tea (L. nummularia). A dye is extracted from the common loosestrife that is used for dying wool yellow, brown, or black.
