Trillium oostingii, commonly known as Wateree trillium, is a species of flowering plant in the family Melanthiaceae. It is endemic to the central part of the US State of South Carolina. Wateree trillium grows under a canopy of deciduous trees such as bitternut hickory, black walnut, slippery elm, box-elder, and various oak species, in rich floodplain soils. Here it forms large colonies alongside mayapple, another spring-flowering herb. Wateree trillium most closely resembles the sessile-flowered trilliums, T. lancifolium and T. recurvatum, but is distinguished from these chiefly by floral

It is closely related to the waterwheel plant (Aldrovanda vesiculosa) and the cosmopolitan sundews (Drosera), all of which belong to the family Droseraceae. Dionaea catches its prey—chiefly insects and arachnids—with a "jaw"-like clamping structure, which is formed by the

It is native to the southeastern United States in seepage bogs and roadside ditches. Its name grit St. Johnswort comes from its limited distribution, within the Altamaha Grit region of the Georgia coastal plain. According to "Hypericum Online", it is found from Maryland to southern Illinois, south to Florida and Louisiana, though this may be in error, as many other sources list it as occurring only in Georgia and
