RESUMO

An epidermal analysis of vegetative and reproductive organs of 28 medicinal ferns from Córdoba Province (Argentina) has been carried out. The objectives were: a) to characterize in detail the epidermis of the organs; b) to contribute to the delimitation at specific level in cases of close morphological similarities; c) to provide additional information for a quality control of the commercialized ferns. Hair types, scales, microscales, respiratory structures, and epidermal cells features are described in detail. For each taxon, a description with illustrations and photographs are provided. Trichomes and type of stomata are novel data for some taxa. From a taxonomical point of view, indument and stomata types were the most significant characters to differentiate the taxa. The contribution to the quality control is summarized in the differential key and the iconography that allow the identification of a vegetal drug when it is fragmented or powered.
