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).

The more recently described Phemeranthus thompsonii may be indistinct from P. validulus and perhaps should be merged with it.
