Additional Information at NatureServe

Diagnostic Characteristics:
This delicate orchid has finely linear or grass-like leaves (5 dm x 4 cm). There is only one leaf per plant and it arises from the base of the plant. There are very few flowers per plant. Also distinctive is the lip which is uppermost in position on the flower.

Management:
Exotic pest plants are a threat to this species. The habitat for this species is very specialized and not likely to withstand much alteration. Grazing or browsing pressure, vegetation removal, hydrologic changes (i.e. vegetation removal in the vicinity or upstream, stream alterations) would be detrimental. May tolerate some timber removal if done without excessive soil disturbance (discing/chopping) and if immediate vicinity of plant is protected from debris and direct cutting etc. Disturbance of surrounding slopes such as ATV trails or timber removal or any activity that results in increased erosion and weed invasion will be detrimental.

Global Range:
Widespread throughout the East from Newfoundland, and Ontario south to Florida, Texas, Cuba and the Bahamas, west to the Central and Lake states.
