Discussion
Of conservation concern.
The description of Platanthera integrilabia is based on a limited sample and is likely too restrictive.
Flowers of this species are nocturnally sweet-scented. The vegetative habit is distinctive, with leaves restricted to the base of the stem and a relatively few-flowered inflorescence borne atop a tall bracted scape. In addition to the normal tuberoid, roots often enlarge distally to form bud-bearing tuberoids at a marked distance from the parent stem, giving rise to diffuse clonal colonies.
