Bahama Brake (Pteris bahamensis (J. Agardh) Fée)

POWO has merged this species into longleaf brake (Pteris longifolia), but most other authorities keep them separate. We reject the merge on the grounds that this species is diploid and that one is tetraploid, and thus they do not readily hybridize, although they are closely related and can when the polyploidy of an individual switches, similarly to birches (Betula sp.)
