Discussion
Spiranthes eatonii is easily confused with S. lacera var. lacera (and in herbarium specimens with S. floridana, S. brevilabris, S. tuberosa, and S. torta), except that it flowers in the winter and spring. It is the only white-flowered, basal-leaved Spiranthes within its range to bloom at that time of year. The narrow, oblanceolate leaves are distinctive within this group.
