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.
