Abstract (in english)
   Fossils from the Whetstone Horizon of central Bohemia, previously refered as the 'early form of A. grandinioides Kessler¨, are shown to be indistinguisable in pinnule morphology and venation from Alethopteris distantinervosa Wagner.This new evidence allows the diagnosis of A. distantinervosa to be emended, providing better information on its morphological variation and epidermal structure. A. distantinervosa occurs in floras of late Duckmantianto Bolsovian and possibly early Westphalian D age in central Boghemia, Saar-Lorraine, Ibbenbüren and South Staffordshire. A. grandinioides Kessler sensu Wagner, non Kessler s.s. ´(=A. pseudograndinioides Zodrow and Cleal)does not appear to occur in Floras older than middle Westphalian D in age.
