Discussion

Of conservation concern.

Trillium reliquum recently has been reported from Alabama; I have not seen specimens from there. Otherwise, the species occurs in Clay, Early, and Richmond counties, Georgia, and in Aiken County, South Carolina. It is currently listed as an endangered species in the United States.
