Discussion | Although Paronychia franciscana was described from California, where it has been known from the San Francisco area since 1887, the species is native in Chile. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The Louisiana record of Paronychia patula, based on a specimen at NY, is questionable. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
