Discussion
Spiranthes torta is restricted to the rocky pinelands in southern Florida and is easily recognized by its nodding flowers and downward-pointing lateral sepals. It could only be confused with S. tuberosa, typically a much shorter plant with pure white flowers.
Spiranthes amesiana Schlechter is often included as a synonym of S. torta; recent studies indicate that it may be a distinct species. It is said to differ from S. torta in its denser inflorescence, spade-shaped lip with a crenulate-ciliate margin, and densely pubescent basal calli. Within the area covered by the flora, it is restricted to extreme southern Florida; it also has been collected in the Bahamas and Nicaragua.
