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).

Most populations of Phemeranthus mengesii are diploid but a few scattered in western Georgia are tetraploid, probably the result of autopolyploidy (W. H. Murdy and M. E. B. Carter 2001).
