Platantherablephariglottis (Willdenow) Lindley. Subgenus:Blephariglottis. Section:Blephariglottis. Small White Fringed Orchid. Phen: Jul-Sep. Hab: Seepages, sandhill-pocosin ecotones. Dist: NL (Newfoundland) west to MI and IL, south to GA.
Origin/Endemic status: Native
Taxonomy Comments: Following Brown (2006b), it seems best to recognize the two white-fringed orchids as separate species; they are morphologically distinctive, and where they co-occur their blooming times are offset.
