Abstract:A new hybrid,Micropolypodium xbradei, from Rio de Janeiro, Brazil, is described and illustrated. It shows intermediate morphology between its parents,M. setosum andTerpsichore achilleifolia, in dissection of blades and veins, and number of sori per segment. New combinations for Brazilian endemic species are presented based on this hybrid and on recent results in grammitid phylogenetics.
