Hypericum virgatum var. acutifolium (Elliott) J.M.Coult.
Hypericum erythreae, the Georgia St. John's-wort, sparse-leaved St. John's-wort, or grit St. Johnswort, is a species of flowering plant in the St. John's wort family, Hypericaceae.[1][2][3] It is native to the southeastern United States in seepage bogs and roadside ditches.[3] Its name grit St. Johnswort comes from its limited distribution, within the Altamaha Grit region of the Georgia coastal plain.[3]
According to "Hypericum Online", it is found from Maryland to southern Illinois, south to Florida and Louisiana,[4] though this may be in error, as many other sources list it as occurring only in Georgia and South Carolina.[1][2][3][5]Kew's Plants of the World Online notes that it may be extinct in South Carolina.[1]
