Discusión taxonómica
There are five species of Bommeria, all in the New World (southwestern United States to Costa Rica), mostly in dry, rocky regions. All five occur in Mexico. Bommeria is related, but not very closely, to Hemionitis as shown in its netted veins, gymnogrammoid sori, and pedate fronds.A
