typical accessory element in EWU (about 6 specimens at MM, much more at BP). ANDREÁNSZKY (1966) compared this leaf from with U. drepanodonta GRUBOV from the Oligocène of Kazachstan (see KRYSHTOFOVICH 1956) and also MAI & WALTHER (1978) did the same. We prefer the earlier name based on European material. True U. drepanodonta GRUBOV possesses more markedly lobate leaf apex in many cases (Z. K pers. observ. at Leningrad), in other respect closely recalling U. fischeri. NAGY & PÁLFALVI (1963, pl. 9, f. 1) bring a picture of U. fischeri (sub ULMUS sp.). Ulmus pyramidalis GOEPPERT, 1855 (Plate V: 1) Slender lanceolate, 3-5.5 x 8-11 cm large, finely simple (to slightly double) serrate leaves with symmetrical base, cuneate to very slightly cordate, and dense numerous secondaries, rarely forked, are typically represented in EWM, exceptionally in EWL (MM 61.977.1,61.963). Prevailing part of the record was identified by ANDREÁNSZKY (1966, textf. 28-30) as Carpinus grandis UNG. He was obviously influenced by a misleading interpretation of ETTINGSHAUSEN (1866). As rightly stressed by BÖZEK (1971), such leaf forms are elms. In a few cases this form can be recognized in EWU (e.g. sub Castanopsis sp. I. sensu ANDREÁNSZKY 1966, textf. 31, MM 56.1342.1). Ulmus pseudopyramidalis sp.n. (Plate VI: 1) Diagnosis: Leaves oblong, 2-4 cm wide and 8-12 cm long, acuminate at the apex, rounded to truncate, mostly markedly asymmetric at the base, simple (to finely double) serrate. Teeth broad, mostly blunt. Venation craspedodromus, midrib straight, secondaries dense, in 12 to 20 pairs, at angles of 40°-90° to the midrib, rarely forked, tertiaries dense percurrent, rarely preserved. H o 1 o t y p e : s.n. MM (Plate VI: 1) - EWU - Paratypes: MM 6689, 3281,1334, 56.1095. - EWU. We agree with ANDREÁNSZKY (1966) that some forms of the elm leaves occurring in EWU do not exactly agree with U. pyramidalis GOEPPERT. They differ first of all by the strongly asymmetrical leaf base, coarser teeth and partly also by the greater size. ANDREÁNSZKY included this form into his Ulmus-type II (1. c. textf. 6264) and partly also to Ulmus-type III (1. c. textf. 65). It is represented both at MM and BP in several, but rarely complete specimens. Without knowing the associated type of fruits we do not suggest relationship to any recent species as also ANDREÁNSZKY (1966) did. One of the fragmentary specimen of U. pseudopyramidalis was identified by PALFALVY (in NAGY & PALFALVY 1963, pi. 9, f. 6) as U. longifolia UNG. nom. illegit. Ulmus sp. Smaller, asymmetrical laef forms (ANDREÁNSZKY 1966, Ulmus-type IV V textf. 66-69) occur both in EWM and EWU, in either level in low frequency. Most of the material is kept at BP and deserves a special study. A monographic treatment was being prepared, but not finished by Mrs. CZIFFERY-SZILLÁGY. ? Zelkova zelkovifolia (UNGER, 1843) BÙZEK et KOTLÁBA in KOTLÁBA, 1963 (Plate V: 3) A single leaf and its counterpart (MM W 1442) from EWM matches by ovate, slightly asymmetrical form and coarse simple teeth with Zelkova. If our identification is correct then this species was extremely rare in EW. NAGY & PALFALVY (1963) noted the occurrence of Zelkova ungeri Kov. nom. illegit. but we have not found such specimens at MÁFI.
