SSAR 9th Edition Comments:
Populations in the Ridge and Valley Physiographic Province of eastern Tennessee have a complex history of hybridization with nearby species (see Tilley et al., 2013, Ecology and Evolution 3: 2547–2567; Pyron et al., 2022, Ecology and Evolution 12: e8574).
Range maps are based on curated specimens and provided gratis by CNAH.
