Abstract
Tanaitis furcihasta, gen. et sp. nov. is described from the lower Frasnian (lower Upper Devonian) of Pavlovsk in the upper reaches of the Don River (U.S.S.R.). Its fertile appendages and spores are similar to those of Archaeopteris while the sterile appendages are unwebbed as in aneurophytes. This plant might form a link between the Aneurophytales and Archaeopteridales.
