I am an amateur botanist working on the fern and lycophyte florulas of Santa Catarina Island and the Furnas River Reserve, in southern Brazil.

The alate rachis that is decurrent along the petiole would suggest Tectaria decurrens. However, the breaks in this tissue at each pinna is in conflict with that species. This plant may be a hybrid between T. decurrens and T. repanda, which Holttum (1991) reports being...

  Both species are similar in having 1-pinnate-imparipinnate laminae, entire and linear pinnae, and free venation with simple or furcate veins. In Pteris longifolia, however, the pinnae are articulated to the rachis, whereas in P. vittata they are not (i.e., each pinna has a short petiolule that is continuous to the rachis). The pinnae base shape can be helpful too: cordate in P. longifolia vs. truncate in P. vittata.
