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.

We agree with B. L. Turner (1983b) in not adopting the four varieties of Paronychia jamesii that Chaudhri recognized. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
