Bommeria

Bommeria is a genus of small pteridaceous rock ferns, native to the New World.

Bommeria is a "gymnogrammoid" fern, exhibiting unprotected sori aligned along veins on the undersides of the fronds.

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.

As of January 2020[update], the Checklist of Ferns and Lycophytes of the World recognized the following species:[3] B. subpaleacea Maxon B. pedata (Sw.) E.Fourn.

(western Mexico and Central America) B. hispida (Kuhn) Underw.
