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.) |
Of conservation concern. Paronychia maccartii is still known only from the type collection in Webb County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
