Thelypteris conservation spores gametophyte. Spore morphology, gametophyte development and conservation of Thelypteris abbiattii and T. hispidula (Thelypteridaceae) in Punta Lara Natural Reserve, Buenos Aires. The morphology of the spores and the gametophyte development of Thelypteris abbiattii and T. hispidula from Punta Lara Natural Reserve (Buenos Aires, Argentina) were studied. Spores are monolete, folded, the folds have an equinated margin and a supralesural fold is also observed. The spore germination was conducted in Dyer medium and occurred between 7-12 days. In both species the germination is Vittaria type and the gametophyte development is Aspidium type. Adult gametophytes were observed after 50 days, are typical cordate and bisexual. Depending on the species, sporophyte formation occurs between 90 to 130 days. There were differences between the species analyzed in the time of appearance of the hairs of the gametophyte and pubescence of first leaves of the sporophyte. The results contribute to the systematic of these ferns and to conservation studies that develop in Argentina Se estudiaron la morfología de las esporas y el desarrollo de los gametofitos de Thelypteris abbiattii y Thelypteris hispidula de material proveniente de la Reserva Natural Punta Lara (Buenos Aires, Argentina). Las esporas son monoletes, plegadas, con pliegues de margen equinado y con pliegue supralesural. La germinación de las esporas se realizó en medio de Dyer y se produjo entre los 7 a 12 días. En ambas especies la germinación es del tipo Vittaria y el desarrollo del gametofito tipo Aspidium. Los gametofitos adultos se observaron a partir de los 50 días, poseen forma cordiforme típica y son bisexuales. Dependiendo de las especies, la formación del esporofito se produce entre los 90 a 130 días. Se encontraron diferencias entre las especies analizadas en cuanto al tiempo de aparición de los pelos del gametofito y la pubescencia de las primeras hojas del esporofito. Los resultados encontrados contribuyen a la sistemática del grupo y a los estudios de conservación que se desarrollan en la Argentina.
