This thesis deals with the sphenopterid types of ferns from the Czech Carboniferous basins. Thesis is presented as a combination of two published papers in peer-reviewed journals, one manuscript in review and one manuscript ready for submission. The actual text of the thesis is a general introduction with introduction to the study subject of sphenopterid ferns, methodology, studied type collections, terminology and the result of my study. The introduction of the thesis provides a general overview of the ferns and history of their studies. All four papers presented here are focussed on modern redescription, redefinition, emendation and revision of genera Boweria Kidston, Dendraena Němejc, Sturia Němejc. Based on the revision of these genera, following two new genera were established: Kidstoniopteris gen.nov. and Paraszea gen.nov. A new species Boweria nowarudensis has been described during the course of this study. The "whole plant concept" was applied to all studied specimens, which allows to obtain as much information on the ferns morphology, anatomy, and reproductive organs as possible. This was combined with data on in situ spores as well as sedimentological and petrological analyses. The sporangial cells as annulus, stomium and apical cells and in situ spores were described for all genera and...
