Perspectivas en el estudio de las Pteridofitas

In the beginnings, the study of the pteridophytes was supported mainly in the morphology of the sporophyte. As a result of the development and the advances in other disciplines and the technological improvements in observation systems as well as field and laboratory techniques, a clear and evident disciplinary interrelationship has arisen and a revision of old concepts has been necessary with the consequent modification of ideas and theories about the biology of the pteridophytes. We intend to show the development of the taxonomy of the pteridophytes from the early days to the different modern approaches used today to understand the present problems through the principal fields of research and the most significative contributions.
