Discusión taxonómica

Cheilanthes bonariensis superficially resembles Astrolepis sinuata in dissection and heavy indument, but the latter species has indument abaxially of pectinate scales rather than long, matted hairs. There is considerable variation in the number of pinna lobes (3–8 pairs per pinna) and degree of cutting, occasionally less than 1⁄4 to 3⁄4 of the way to the costa.
This is the most widespread and abundant pteridophyte species in Mexico, being in all states except Baja California Norte, Tabasco, and those of the Yucatan Peninsula.
