On yesterday's blog page I discussed the update of ladies'-tresses done by Pace and Cameron in 2017. Most prominently for we Michiganders, Spiranthes cernua is gone, split into two species. Spiranthes incurva, the Sphinx ladies'-tresses, was shown on yesterday's page. Sphinx is named for its cryptic nature. Cryptic species are ones that are genetically distinct, but look alike. Spiranthes arcisepala is the other half. Appalachian ladies'-tresses is cryptic enough that it was only described for science in 2017. It is not yet entirely clear if this species reaches Michigan, but it certainly gets very close. This image is from Lucas County, Ohio, immediately south of our border. Pace and Cameron in their 2017 discussion of the Spiranthes cernua complex show a range of CT, IN, MA, MD, ME, MI, NC, NH, NJ, NY, OH, PA, TN, VA, VT, WV, ON, and QC. Lucas Co OH, 9/12/21. Orchid family, Orchidaceae.
