Dispersed miospore and pollen assemblages are described from the Radnice Basin, Middle Pennsylvanian, Czech Republic. Conversion factors (R-values) were produced by comparing the palynological data with quantified macrofloral data, to relate the percentages of spore/pollen taxa to those of the major plant groups that produced them. Among arborescent lycopsids, the miospore and macroplant counts are more or less equal. In other lycopsids miospores are strongly over-represented, as their macroplant remains were relatively fewer than would be suggested by the proportion of their spores in miospore spectra. Sphenophyll and calamitid macroplants were also relatively fewer than are their spores as a proportion of palynological spectra. By contrast, macroplants of ferns and cordaites are relatively more numerous than are their miospores and pollen in palynological spectra.

分散的小孢子和花粉组合来自捷克共和国宾夕法尼亚州中部的拉德尼采盆地。转换因子（R 值）是通过将孢粉学数据与量化的宏观数据进行比较产生的，以将孢子/花粉类群的百分比与产生它们的主要植物群的百分比联系起来。在乔木石松中，小孢子和大型植物的数量或多或少是相等的。在其他石松属中，小孢子的表现明显过度，因为它们的大型植物残骸相对少于它们在小孢子光谱中的孢子比例所暗示的。作为孢粉谱的一部分，蝶叶和棒状大植物也相对少于它们的孢子。相比之下，
