Morphological characters of «Bolbitis serratifolia» (Dryopteridaceae) from Argentina

Abstract

The study of this species was based on the morphological characters of the sporophyte with the goal of contributing new data to the understanding of the genus. It was compare to another genus of Dryopteridaceae and different diagnostic characters were proved. Architecture of fronds, morphology of the indument of blade and axis, epidermal patterns of pinna, stomata and spores were under consideration for this study. Dimorphic leaves, imparipinnate, anastomosing veins with free included excurrent veinlets, stem provided with scales, glabrous blades, and trilete spores are morphological characters that allow identifying this species
