Paronychia drummondii
Paronychia echinulata
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.

Paronychia echinulata was for many years known as P. echinata Lamarck. The latter cannot be used since, as Chater noted, it is a superfluous name for Illecebrum cymosa Linnaeus [= P. cymosa (Linnaeus) de Candolle].
