Abstract

Several most recent geological investigations, especially in the N. part of the Plzen coal-basin have shown that various coalseams, previously regarded as Upper Stephanian really belong to a much deeper horizon, being enclosed within the so called Lower Red Beds (i.e. the uppermost part of the Westphalian till the Lower Stephanian). This discovery led the author to a new evaluation of the various Stephanian floras in the Czechoslovakian coal basins. Four different biostratigraphically well-defined plant assemblages have been distinguished here during the time space between the uppermost Westphalian (i.e. the Nyrany coal series) and the Permian.
