Lachnanthes
（重定向自Redroot）
Lachnanthes is a genus of monocotyledonous plants in the bloodwort family containing only one species, i.e., Lachnanthes caroliniana, commonly known as Carolina redroot or bloodroot. The plant is native to eastern North America, from southeastern Nova Scotia (especially the Molega Lake area) and Massachusetts in the north, south to Florida and Cuba, and west along the Gulf of Mexico to Louisiana. It has also been reported from an island in the western Caribbean off the coast of Honduras. It prefers wet, acidic, usually sandy soils, restricting it to various wetland habitats such as bogs, pinelands, hammocks and pocosins, among others.
