Discussion | Chaudhri described two subspecies of Paronychia drummondii based on differences in leaf pubescence, flower size, and style length. We follow B. L. Turner (1983b), who noted that many specimens demonstrate intermediate characteristics, suggesting that taxonomic recognition not be given to the extremes.

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.) |
