Yellow? Well, it's less white than other ladies'-tresses, but it seems to want to be one of that tribe. As the flowers age, they become more white. Because of that, and because it just looks a lot like nodding ladies'-tresses, this species was not finally accepted until 1980. Colorless dried herbarium specimens are notoriously hard to identify. Some would still lump this together with the nodding (S. cernua). The herbarium problem could mean that it might not be a sure thing to say yellow ladies'tresses grows in CT, IN(T), KY(S), MA, MD(E), ME, MI, NH, NJ, NY(V), OH, PA, RI, TN(X), VA, VT, WI, WV, NB, NS, ON, and PE. Monroe Co MI, 9/8/15. Orchid family, Orchidaceae.
