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]

Georgia St. John's wort was first formally described as Brathys erythraeae in 1836 by Édouard Spach. In 1840, Ernst Gottlieb von Steudel moved it to the genus Hypericum . [6] [5]
