Bommeria
Sign in to saveBommeria 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. The same set of analysis has shown many presumed genera within this family to be paraphyletic, but the small genus Bommeria appears to be monophyletic, or a natura

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. The same set of analysis has shown many presumed genera within this family to be paraphyletic, but the small genus Bommeria appears to be monophyletic, or a natural genus.
Bommeria is a "gymnogrammoid" fern, exhibiting unprotected sori aligned along veins on the undersides of the fronds. This is why it was assumed to be closely allied to Hemionitis. Such a feature is strongly at odds with most pteridoid ferns (Pteridaceae), which typically have linear marginal sori with an indusium, and sometimes protected with a reflexed leaf tissue margin. Apparently, this is a trait that can arise independently, and may be an atavistic trait.
