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).

Reports of Phemeranthus brevifolius from western Texas and southern New Mexico, where it does not actually occur, apparently have been based on misidentified specimens of P. brevicaulis.
