Discussion | Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Species 20-30 (5 in the flora). Mature achenes are necessary for certain determination. Parietaria nummularifolia (Schwartz) Weddell was collected once in 1992 in Palm Beach County, Florida, in mesic woods bordering a creek (R.P. Wunderlin, pers. comm.). This species is occasionally cultivated, and the Florida collection probably represents an escape. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
