This species can be identified by its habitat, spreading, dark-colored sepals, and white petals.
The genus name Pogonia derives from the Greek "pogo(n)" meaning "bearded" referring to the bearded lip of some species.
The species epithet divaricata derives from the Latin "divaric(a)" meaning "spread apart" referring to the sepals.
A synonym for this species is Cleistes divaricata (L.) Ames
Some authors recognize a similar plant, P. bifaria (Fern.) P.M. Br. & Wunderlin based on corolla lip size (21-33mm long compared to 34-56mm long for P. divaricata).
