REVIEW OF THE FLORA In the following systematic part a critical re-appraisal of the EW flora is given. Most of the original specimens of ANDREANSZKY'S studies have been spotted in MM and BP together with some more identifications that ANDREÁNSZKY performed but not published when working on the material in BP. We have found great difficulties in revising PÁLFALVY'S collections in MAFI because only a few identification labels are attached to the specimens that obviously serred the basis of his studies. Hence we comment in more detail only what we have been able to examine authentically. EQUISETOPSID A EQUISETACEAE Equisetum sp. div. (Plate I: 3) Ribbed casts of horsetail stems 13-20 mm across, partly flattened with nodes at various intervals (15-35 mm) occur but rarely in EWU. ANDREÁNSZKY (1955) compared more robust specimens with£. maximum L., he identified slender ones as E. braunii UNG. However, the specimens are insufficient to allow specific determination. FILICOPSID A Among the so far published records of ferns we have not been able to verify the occurrence of Trichomanes radicans L. sensu ANDREÁNSZKY (1949a, pl.9, f.l), Osmunda parschlugiana (UNG.) ANDREÁNSZKY (syn. Osmunda heerii GAUDIN) sensu PALFALVY (1951, pl. 1. f. 5, in NAGY & PALFALVY 1963, pl. 4. f. 3.), Gleichenia sp. sensu NAGY & PALFALVY (1963), Lygodium gaudinii HEER sensu NAGY & PALFALVY (1963), Woodwardia roessneriana (UNG.) HEER sensu NAGY & PALFALVY (1963) and Woodwardites sp. sensu NAGY & PALFALVY (1963, pl. 4. f. 6. ). Such remains are obviously extremely rare. OSMUNDACEAE Osmunda lignitum (GIEBEL, 1857) STUR, 1870 (Plate I: 4). Partly fragmentary pinnae with shallow lobes of rounded pinnules (about 6 mm wide) attaining a length of more than 10 cm and width up to 2.5 cm. They are rarely found at EMU (a single specimen in MM, more than 10 specimens in BP). The terminal pinna shows gradually shallowing lobes (the type-specimen of O. legányi ANDREÁNSZKY ) while side pinnae are abruptly narrowed at the apex. Although some identifications of ANDREÁNSZKY and PALFALVY are erroneous (see Pronephirum stiriacum) NAGY & PALFALVY (1963, pi. 4. f. 4) figured a very typical specimen with free, non-anastomosing venation (see also BARTHEL 1976). We hesitate to accept view of some authors to separate this species into the genus Osmundastrum PRESL.
