Platanthera blephariglottis (Willdenow) Lindley. Subgenus: Blephariglottis. Section: Blephariglottis. Common name: Small White Fringed Orchid. Phenology: Jul-Sep. Habitat: Seepages, sandhill-pocosin ecotones. Distribution: 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. Hartvig et al. (2022) argued that spur length difference is geographically clinal, associated with different pollinators, and that the variation should be regarded as taxonomically meaningless

Horticultural Information
Intro: Erect perennial of boggy streamhead margins and seepages, pitcher plant bogs and sandhill-pocosin ecotones.
Stems: Stem unbranched, smooth.
Leaves: Leaves alternate, sessile-sheathing, strongly ascending, broadly lance-shaped, 2-13 in. long (but reduced to bracts upward) and folded lengthwise ("keeled").
Inforescence:
Flowers: Flowers 20-45 in a dense, cylindrical, terminal raceme; snowy white; about 3/4 in. long; bilaterally symmetric; with 2 small upper petals plus 1 of 3 sepals forming a small hood, beneath which projects a deeply fringed lip-petal bearing a curved spur (longer than the lip, 1/2-1 in.).
Fruits: Fruit an ellipsoid capsule.
Comments:
Height: 1 1/2-2 1/2 ft.
