. As a relict species, there are a few remaining groups but it was once more abundant when conditions were different. Significant habitat loss has occurred through clearing of forests for agricultural and pine farm uses. On April 4, 1988, it was officially listed as an endangered species. The common name varies by location. It grows in undisturbed hardwood forests that sometimes include mature pines and that are free of understory plants such as bushes and vines. It likes moist, well-drained soils along the banks of streams and small stream floodplains, mixed with other wildflowers and forest debris. ''Trillium reliquum'' was first collected near Augusta in 1901 but was not described as a new

Future

The U.S. Fish & Wildlife Service lists this plant as surviving in 21 sites in Alabama, Georgia and South Carolina. The relict trillium has also been found in Tennessee and Florida. The reasons for the restrictions of this formerly widespread plant to only a few locations is not entirely clear. It is not commonly collected in the wild (for aesthetic or other uses) and is therefore considered relatively safe, in spite of its endangerment. There is no evidence that its numbers have declined recently.
