YANEZ, Agustina; MARQUEZ, Gonzalo J.  y  MORBELLI, Marta A.. Primer registro de Dennstaedtia dissecta: Dennstaedtiaceae) para la flora argentina. Darwiniana [online]. 2012, vol.50, n.2, pp.332-338. ISSN 0011-6793.

Dennstaedtia dissecta is recorded for the first time for the Argentinean flora in the Misiones Province. This new record was discovered during the study of herbarium specimens from BA and LP, and then corroborated with field collections from Cruce Caballero Provincial Park and Urugua-í Provincial Park. In addition to the characteristics of rhizome and lamina, the spores were an important information source for the identification of this species. The diagnostic characters are described and illustrated, including a key to identify the species of Dennstaedtia from Misiones.
