BLECHNACEAE Blechnum dentatum (GOEPPERT, 1836) A. BRAUN, 1852. (Plate II: 3) Complete bases, very asymmetrical, truncate, and middle parts of pinnae with slightly dentate margin, rather variable in the width (11-20-33 mm), are a common accessory member of EWU. A more complete specimen was figured by PALFALVY (1980, pi. 3, f. 3.) under this name while ANDREÁNSZKY (1952,1966) preferred B. BRAUNII ETT., its later synonym (see BARTHEL 1976). On the average, the type-material from Lower Miocene of North Bohemia is slender. ASPLENIACEAE Asplenium egedense ANDREÁNSZKY, 1949 So far a single specimen of this obviously extremely rare fern has been recovered in EWL (ANDREÁNSZKY 1966, Textf. 2, MM, No. 61.803.1). Traces of venation, faintly seen in glycerin bath and also sori, clearly demonstrate the identity with the type from Kiseged. Very similar fern remains have been known from the Tertiary of Italy as Anemia sepulta SouiNABOL (1981, pi. 14, f. a). THELYPTERIDACEAE Pronephirum stiriacum (UNGER, 1847) KNOBLOCH et KVACEK, 1976 (Plate I: 2) Up to 25 cm long, more or less complete fans with longitudinally ribbed rhachis (up to 5 mm wide) and isolated shallowly crenulate to more deeply incised pinnae (more than 12 cm long), asymmetrical and cordate at base, up to 2.5 cm wide, with goniopterid type of venation, are common in EWU. A fertile specimen was figured by PALFALVY (1980, pi. 4, f. 1). ANDREÁNSZKY (1966, 16, textf. 1) argued the EW records to be specifically different from Pronephrium stiriacum and called them Lastraea cf. oeningensis (A BR.) HEER but we do not share this view (see also BARTHEL 1976, PALFALVY 1980). Some small Fragments in MM and MÁFI were erroneously identified by ANDREÁNSZKY and PALFALVY as Osmunda lignitum (at MM and MÁFI) which occurs but rarely in EWU. ? POLYPODIACEAE vei ASPIDIACEAE (Plate 1: 1). A fragment of two pinnules, partly fused, sterile, finely dentate, 4x7 mm size, with sharp sinuses, a bent thin midrib and rarely forked, not anastomosing craspedodromous secondaries has been newly found in MM (No. 56.1344.1) in the undetermined material of EWU. It may correspond to Aspidium or Pteris sensu NAGY & PALFALVY (1963) or Pteridium crenatum (WEBER) GIVULESCU see GIVULESCU (1973).
