Glossary (beta!)

Origin/Endemic status: Endemic

Taxonomy Comments: Apparently previously confused with S. lacera, S. floridana, S. brevilabris, and S. tuberosa, but considered by Brown (1999) to be distinctive in the combination of spring blooming season, white flowers, and basal, narrowly oblanceolate leaves. Dueck, Aygoren, & Cameron (2014), Pace (2015), and Pace & Cameron (2017) found insufficient reason for distinguishing S. eatonii from Spiranthes lacera. We consider the matter unresolved.
