Mesozoic macroflora from Poland

Acta Societatis Botanicorum Poloniae, the journal of the Polish Botanical Society, founded in 1922, published a special collection of papers entitled Polish Botany Centennial. Among five palaeobotanical reports there is a historical synthesis of research on Mesozoic macrofloras. It contains, among others, three palaeovegetation reconstructions (Early Jurassic of the environs of Cracow and of the northern margin of the Holy Cross Mountains, Late Cretaceous of Lower Silesia). A short interpretation of research on Cretaceous floras in terms of philosophy of science is also given, signalling the phenomena of paradigm shift and social context of science.
