Abstract

A new bisporangiate lycopsid cone genus Thomasostrobus gen. nov. from the Stephanian strata of the Intra-Sudetic Basin (Czech Republic) is proposed as a new organ genus. The only species in the genus, Thomasostrobus longus sp. nov., is established. Mega- and microsporangia are arranged in zones, with megasporangia in the lower part of the cones and microsporangia in their apical portions. Microspores assigned to the dispersed genus Cadiospora and megaspores comparable with the dispersed species Sublagenicula levis, are described in situ for the first time. The possible parent plant of Thomasostrobus longus is discussed and an overview of dispersed Cadiospora and Sublagenicula spores is given.
