Iliamna corei is known from a single locality on Peters Mountain at Narrows, Virginia. The species is considered critically imperiled globally. Whether it is distinct or not from I. remota, with which it is sometimes allied, has been problematic, but recent genetic studies support their recognition as distinct species (T. A. Bodo Slotta and D. M. Porter 2006).
Iliamna corei is in the Center for Plant Conservation’s National Collection of Endangered Plants.
