Discussion | 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.) |
Chaudhri used duration and pubescence to recognize two subspecies of Paronychia baldwinii, characters that L. H. Shinners (1962c) found to vary independently in this species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
