Abstract:
A taxonomic revision of the fossil equisetophyte genera showed that the generic name Annulinaa proposed by Neuburg in 1954 did not meet the requirements of the International Code of Botanical Nomenclature (ICBN) (see Greuter et al, 2000) and, therefore, was invalidly published until substantiation by Rasskazova (1961b). However, the generic name Annulina is preoccupied by the green algae Anmilina Link (Chlorophyceae: Cladophoraceae) (Link, 1820). Therefore, the generic name established for the fossil genus of the Equisetophyta is replaced by Umbellaphyllites.
