Discussion

Some populations of Phemeranthus calycinus are diploid while others are tetraploid, the latter probably the result of autopolyploidy (W. H. Murdy and M. E. B. Carter 2001).

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).
