Chrysogonum Linnaeus. Green-and-gold.
A genus of 3-4 species and 3-4 taxa, perennial herbs, of se. North America. Nesom (2020) elevated var. brevistolon to species rank. Schilling & Floden (2018) suggested "that patterns of differentiation within [C. virginianum] are complex and will require adjustment beyond simply elevating the varieties recognized by Nesom (2001) to species level" (Schilling & Floden 2018).
