Discussion
Cheilanthes bonariensis has been assigned to Notholaena in past treatments. It is distantly related (at best) to the species here included in Notholaena, however, and we concur with R. M. Tryon and A. F. Tryon (1982) that it should be transferred to Cheilanthes. Chromosomal studies (G. J. Gastony and M. D. Windham 1989) suggest that C. bonariensis is an apogamous triploid that arose through autopolyploidy. Further investigation is necessary to determine whether 64-spored, sexually reproducing populations of C. bonariensis are still extant.
