The spore germination and gametophyte development of Ctenitis submarginalis from Punta Lara Natural Reserve, Buenos Aires province were studied as a contribution to the conservation of the species in this protected area. Spores collected from natural populations were sowing in Dyer medium and germinated in six day with a percentaje of 88 % fifteen days after sowing. The germination is Vittaria type and the gametophyte development is Aspidium type. The gametophyte of Ctenitis submarginalis is cordate, with a deep notch and well developed and symmetric wings.

Desarrollo del gametofito y conservación de Ctenitis submarginalis (Dryopteridaceae) en la provincia de Buenos Aires, Argentina. Se estudió la germinación de las esporas y el desarrollo del gametofito de Ctenitis submarginalis de la Reserva Natural Punta Lara, provincia de Buenos Aires como contribución a la conservación de la especie en ésta área protegida. Las esporas colectadas de las poblaciones naturales fueron sembradas en medio de Dyer y la germinación se produjo a los seis días, con un porcentaje de germinación del 88 % a los 15 días después de la siembra. La germinación es del tipo Vittaria y el desarrollo del gametofito tipo Aspidium. El gametofito de Ctenitis submarginalis es cordado, con una profunda escotadura y alas simétricas bien desarrolladas. Los gametangios aparecen a los 50 días después de la siembra. El esporofito emerge a los 190 días después de la siembra y dos tipos diferentes de pelos se observaron en la primera lámina. La germinación in-vitro a través de esporas es un método exitoso para la obtención de numerosos esporofitos de Ctenitis submarginalis. Los esporofitos obtenidos fueron gradualmente aclimatados, transplantados a su hábitat natural en la reserva y serán periódicamente monitoreados para contribuir a la conservación de la especie.
