Isotria medeoloides (Pursh) Rafinesque. Common name: Small Whorled Pogonia, Little Five-leaves. Phenology: May-Jun. Habitat: Acidic mesic to dry-mesic forests, in the mountains and upper Piedmont usually with Pinus strobus. Distribution: Widespread (but very local) in ne. North America, from s. ME and MI south to c. and e. WV, w. VA, w. NC, e. TN, and n. GA.
Origin/Endemic status: Native
Other Comments: The reproductive biology of this species was studied by Vitt & Campbell (1997). Van Alstine et al. (1996) discussed the habitats of known occurrences in Virginia.
