Discusión taxonómica
Cheiloplecton is a small genus of two or three species of mesic areas (roadbanks and slopes, often among rocks) of southern Mexico and northern Central America. It is very close to Cheilanthes, but has been commonly placed in Pellaea. Gastony and Rollo (1998) showed Cheiloplecton to be sister to Notholaena. We are maintaining it as a marginally distinct genus because of its broad, doubly recurved margin/indusium.
