Discussion | Of conservation concern. Phemeranthus sediformis is poorly known and merits further study in the field and better representation in herbaria. When its characters and their ranges of variation are better known, it may prove to be indistinct from P. spinescens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Phemeranthus teretifolius is an allopolyploid derived from P. parviflorus and P. mengesii, both of which it evidently outcompetes within its southern Appalachian range (M. E. B. Carter and W. H. Murdy 1985; W. H. Murdy and M. E. B. Carter 1985, 2001). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
