Additional Information at NatureServe

Diagnostic Characteristics:
These plants have small leathery petioled leaves that are cordate (heart-shaped) and without any hairs (wild ginger has hairs on the leaf petioles). They occur among forest leaf litter. This species is distinguished by leaves that are not mottled in appearance. The calyx tube is flask shaped and erect-spreading at the top of the ovary.

Management:
Timber removal would likely result in changes to the moisture and light conditions at the site and be detrimental to this species. Disturbance such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.

Global Range:
Endemic to the Cumberland Plateau of Tennessee and Kentucky, with a few disjunct populations in the Blue Ridge of North Carolina (Weakley, 1996).
