RANAL, Marli A. Development of Adiantopsis radiata, Pteris denticulata (Pteridaceae) e Polypodium latipes (Polypodiaceae) in natural conditions. Acta Bot. Bras. [online]. 1991, vol.5, n.2, pp.17-35. ISSN 0102-3306.

Populations of gametophytes and sporophytes of Adiantopsis radiata (L.) Fée, Pteris denticulata Sw. and Polypodium latipes Langsd. et Fisch, occurring in a semideciduous mesophytic forest in the State of São Paulo, Brazil, were observed during 24 months and samples were collected for study in the laboratory. The morphology of different phases of development, from gametophytes until the formation of adult sporophytes, as well as informations relative to their behavior in conditions of reduced humidity are presented.

Keywords : Heteroblastic development; Adiantopsis radiata; Pteris denticulata; Polypodium latipes; Pteridaceae; Polypodiaceae.
