cf. Myrica integerrima KRÄUSEL et WEYLAND, 1954 (Plate VIII: 4) These elongate leaves with entire margin and thin regular secondaries that form with the stouter midrib wide angles (80-45°) and join by large loops, occur mainly in EWL, less often in EWM and EWU. They can attain a length of over 10 cm. They recall entire-margined Myricas (namely M. tntegerrima KRAUS, et WEYL. common in the Lower Miocene strata) but without anatomical evidence their taxonomic status must remain open, they were identified by ANDREÁNSZKY (1966) as various entities: Lithocarpus debilinervis ANDREÁNSZKY et KOVÁTS ( 1. c. textf. 32, MM 78.03.1), Liûiocarpus colchica KOLAK. (1. c. textf. 34, MM 65.28.1), Myrica cf. longifolia TEYSM. et BlNN. (1. c. textf. 55, BP 67.95.1), Quercus salicina SAPORTA (1. c. textf. 42-44, BP 67.109.1, 67.108.1). Comptonia dryandroides UNGER, 1850 (Plate VIII: 2) Very characteristic linear lobate leaves partly with fully separated lobes, partly with incised lamina halfway to the midrib, with lobes directed towards the leaf apex, often finely toothed, are confined to EWU. We have not attempted to revise this common Oligocène leaf form, known also in Swiss Molasse (e. g. Myrica graeffii HEER) and elsewhere. A part of the leaf forms indeed recall the common Comptonia acutiloba BRONGN. and differ mostly in the form of lobes, which can often be dentate. ANDREÁNSZKY (1955) may have rightly reduced this entity to the variety level (Myrica acutiloba var. dentata ANDREÁNSZKY, 1955, BP 71.418.1) but unjustly established new, clearly conspecific taxa - Myrica grandis ANDREÁNSZKY (1966: 73, nom. nov. for M. grandifolia ANDREÁNSZKY, 1955 non UNGER) and perhaps M. onocleaefolia ANDREÁNSZKY (1955, pl. 2, f. 7). In a discussion with S. G. ZHILIN we arrived to a conclusion that the whole set of forms from Kazachstan to Europe should be studied in order to clarify their taxonomy. Without knowing the details of pubescence it is difficult even to decide the generic assignement. JUGLANDACEAE Engelhardia orsbergensis (WESSEL et WEBER, 1856) JÄHNICHEN, MAI et WALTHER, 1977 (Plate VII: 3) Narrow elongate leaflets, prevailingly sessile, asymmetrically cuneate at base, slightly falcate, widely serrate with very thin teeth and dense semicraspedodromous venation very often occur in EWU, occasionally also in EWM. Some specimens attain a considerable size (Carya falcata ANDREÁNSZKY, 1956, 221. pro parte, pi. 2. f. 3,4, BP 83.261.2), the ordinary leaf form was usually identified by ANDREÁNSZKY (1955, 1966) as Myrica lignitum (UNG.) SAP., but also as Pterocarya denticulata (O. WEB.) HEER (e.g. MM 64.76.1), a single specimen from EWM as Quercus tenerrima Web. (1. c. textf. 38, MM 63.35.1). Engelhardia macroptera (BRONGNIART, 1828) UNGER, 1866 As already stated by ANDREÁNSZKY (1966) the Engelhardia fruits (involucra) are very rare at EW. They show a characteristic triveined pattern. We spotted only two specimens in EWU (MM 55.5842.1, BP 1161). PALFALVY (1981) records both the species in EW (see also NAGY & PALFALVY 1963, pi. 6, f. 2). JUGLANDACEAE gen. (Plate VIII: 5) Asymmetrical leaflets of juglandaceous nature, with semicraspedodromous venation and secondaries diverging from the right to about 45° angles on one side of the midrib and 45-30° on the other, occur very rarely in EWM (MM 64.72.1 sub Juglans cf. cinerea L. in ANDREÁNSZKY 1966, textf. 54, BP 83.295.1 sub Carya falcata ANDREÁNSZKY) and EWL (MM 64.278.1 sub Castanopsis sp., BP W 2518).
