Pogonia A.L. de Jussieu. Rose Pogonia, Pogonia.
A genus of 3 species, of temperate e. North America and e. Asia. Cameron & Chase (1999) indicate that molecular analyses indicate that there may be merit in the traditional broad circumscription of Pogonia to include Isotria and N. American taxa of Cleistes; alternatively, North American “Cleistes” can be segregated as Cleistesiopsis, as done here.
