Discusión taxonómica
Cheilanthes kaulfussii is distinguished by the finely dissected, broadly deltate to pentagonal (rarely lanceolate) blades with abundant, short, erect glandular hairs on the stipes and blades.
It is one of the most widely distributed pteridophytes in Mexico, occurring in 24 states and Distrito Federal. Some specimens from Durango have as few as one sporangium per vein end, but this is possibly a function of smaller plant size.
