Appalachian Ladies’ Tresses was formerly treated as part of the Spiranthes cernua (nodding ladies'-tresses) complex, but after reevaluation it was designated as a separate species in 2017 (Systematic Botany1). It can be found in the mountainous Appalachians from North Carolina and Tennessee north.

This downward arching sepals feature also gives them their scientific name "arcisepala", from the combining of Latin "arcus" (arching) and "sepalorum" (sepals).According to Zachary R. Bradford's article in Sempervirens, The Quarterly of the Virginia Native Plant Society, September 20222, Appalachian Ladies'-tresses' unique combination of characteristics are:
