    • n heuchera A genus of polypetalous dicotyledonous plants, belonging to the natural order Saxafragaceæ, tribe Saxafrageæ, and the type of Bartling's tribe Heuchereæ. The calyx is bell-shaped, the tube cohering at the base with the ovary, 5-cleft; the petals are 5 in number, spatulate, small, and entire; the stamens 5 in number; the styles 2, and slender; and the pod 1-celled, with 2 parietal many-seeded placentæ, and 2-beaked, opening between the beaks. They are perennials, with round heart-shaped leaves, principally from the rootstock. The flowers are in small clusters disposed in a prolonged and narrow panicle, and are greenish or purplish. About 20 species are known, natives of North America and Mexico. The root furnishes a powerful astringent, whence the name alum-root applied to some of the species, particularly H. Americana. H. villosa is sometimes called the American sanicle.
