《古植物志》B部分出版了對古植物學的貢獻，即關于植物形態特征、系統學和系統發育特征的論文，以及關于古氣候學和孢粉地理學的論文。特別值得一提的是在《古植物志B》上發表的關于特定植物區系或植物群的綜合性專著。古氣候或地層問題往往借助于《古地形志》B節所發表的古植物學資料加以澄清。

Section B of Palaeontographica publishes contributions to palaeobotany, i.e. papers on morphological traits, systematics and phylogenetic features of plants as well as papers on palaeoclimatology and palynogeography. Especially worth mentioning are the comprehensive monographs published in Palaeontographica B on specific floras or plant groups. Often palaeoclimatic or stratigraphic problems are clarified by resorting to palaeobotanical data published in Section B of Palaeontographica.
