Re-classification and nomenclatural adjustments in the genus Botryopteris (Pteridophyta)

摘要

During the preparation of a taxonomic synopsis of fossil plants described from the territory of Russian Federation (Fossil Plants of Russia Project), several later homonyms have been found among generic names in current use in palaeobotany. The Botryopteris B. Renault was originally established in 1875 (Renault, 1875a, b) for fossil fertile foliage of so-called Primofilices form the Stephanian Carboniferous of France. Taking into consideration the requirements of the Interanational Code of BotanicalNomenclature with respect to cases of generic homonymy in the plant kingdom (Greuter et al., 2000), I propose to substitute Botryopteris B. Renault (1875a, b) non C. Presl (1825) by a new generic name, Botryopteridium nom. nov.
