Discussion
The few populations of Cheilanthes kaulfussii known in the flora produce 32 spores per sporangium and reproduce apogamously (D. M. Benham 1982). Although the chromosome number of North American specimens has not been established with certainty, the specimens appear to be polyploids that may have been derived from 64-spored Mexican populations through autopolyploidy. The species is quite distinctive and should not be confused with any other member of the flora.
