About fifty compression specimens belonging to four species of Polysporia from the Kladno–Rakovník Basin of the central and western Bohemian Carboniferous continental basins and Intra-Sudetic Basin of the Czech Republic were studied macromorphologically and for in situ spores. Their stratigraphic range is from the Bolsovian to the Stephanian B. Polysporia rothwellii sp. nov., P. drabekii sp. nov. and P. radvanicensis sp. nov. are proposed as new species. Polysporia is reconstructed as a sub-arborescent plant with a principal axis with sterile and fertile apical portions.

Na základě makromorfologie a spor in situ bylo studováno cca 50 fosilních kusů rodu Polysporia z Kladensko-rakovnické a Vnitrosudetské pánve. Stratigrafický rozsah zkoumaného materiálu je bolsov až stefan B. Jako nové druhy byly popsány Polysporia rothwellii sp. nov., P. drabekii sp. nov. and P. radvanicensis sp. nov. Polypsoria byla interpretována jako subarborescentní rostlina s hlavní osou, rozčleněnou na sterilní a fertilní zóny.
