Taxonomy Comments: Whether to recognize two taxa ("virginianum" and "boreale"), and if recognized, at what rank, has been controversial, but is resolved by Jiménez-Mejías, Cohen, & Naczi (2017). Cooperrider (1995) preferred varietal status for this taxon, stating that in OH there are numerous intermediates, while Voss (1996) and Rhoads & Klein (1993) maintained C. boreale at the species level. Haines (2010) added subspecific rank as an additional option. Andersonglossum boreale (Fernald) J.I. Cohen (Cohen 2015) was invalidly published (not accepted by its own author), but later validated (Fernald) Jim. Mejías, J.I. Cohen, & Naczi (Jiménez-Mejías, Cohen, & Naczi (2017).
