A database of all reported Ordovician–Silurian land plant megafossil and dispersed spore assemblages has been assembled. For
each assemblage a list of taxa has been prepared and its location plotted on new palaeocontinental reconstructions. These
new data compilations are analysed with respect to palaeophytogeographical differentiation and various patterns of taxon diversity
and morphological disparity that emerged during the origin, adaptive radiation and geographical spread of land plants. Our
analyses include new quantitative assessments.
