Phemeranthus teretifolius (Pursh) Rafinesque. Common name: Appalachian Rock-pink. Phenology: Jun-Sep. Habitat: In shallow soil over felsic or mafic rocks (granite, gneiss, schist, granite, diabase, greenstone, metabasalt, sandstone, Altamaha grit), especially where periodically wet by seepage (often in mats of the moss Grimmia). Distribution: DE (at least formerly), se. PA, and WV, south to se. TN, GA (where it extends into the Coastal Plain on outcrops of Altamaha Grit), and AL, in the Appalachians and adjacent provinces.
Origin/Endemic status: Endemic
Taxonomy Comments: P. teretifolius is an allotetraploid, probably derived from hybridization of the diploids P. mengesii and P. parviflorus followed by polyploidization.
