Spiranthes

Spiranthes cernua complex

Spiranthes cernua
Nodding ladies'-tresses

Morphologically, the species of the Spiranthes cernua complex are known to be quite variable within species but relatively similar from one species to another. Recent molecular phylogenetic research has redefined this group by moving some species in or out, confirming hybrid origins, and adding newly published species.^[1]
