Bommeria is a genus of small pteridaceous rock ferns native to the New World. Genetic analysis has shown it to be a stem offshoot clade of all the cheilanthoid ferns (in family Pteridaceae) except for Doryopteris which is an even more basal (primitive) stem offshoot. for years it was assumed that this genus was closely allied with Hemionitis but genetic analysis has shown that genus to be a more advanced genus evolutionarily.
