veins. It was found in EWM as well as Berchemia cuneata ANDREÁNSZKY (1962, 232. textf. 8, MM 78.08.1), which we are inclined to consider only as a very large specimen of the same. Another leaf from EWU ascribed by ANDREÁNSZKY (1966,103. textf. 97, BP 70.136.1) to Comus buchii HEER may also belong to T. rhamnoides. ? FAGACEAE gen. (Plate VII: 5) Numerous entire-margined leaf forms occurring mainly in EWL, occasionally also in EWM and EWU recall by its regular eucamptodromous venation Fagaceae but their specific determination is quite impossible. In general they correspond with the "Laurus" primigenia-type (see above p.00). Broader forms were identified partly as Litsea cf. term (L.) MERR. (ANDREÁNSZKY 1966, textf. 13, MM 64.184.1), slender forms as Litsea cf. lancifolia (ROXB.) BENTH. et HOOK- f. (ANDREÁNSZKY 1966, textf. 15), Neolitsea cf. intermedia MERR. (1. c. textf. 16) and Laurus primigenia UNG. (1. c. textf. 17, MM 64.145.1). No essential difference in general shape and venation can be found also in Ficus agriensis ANDREÁNSZKY (1962, 227. textf. 4.MM 78.10.1), partly also in Quercus palaeofoumierii ANDREÁNSZKY et KovÁTS (in ANDREÁNSZKY 1966, 56. textf. 40, MM 78.05.1). A lauraceous affinity cannot be fully excluded but we believe that rather some evergreen Fagaceae are represented by these remains. Unfortunately, the cuticular structure, which would easily solve this problem, has not been preserved in any of the specimens studied. BETULACEAE Alnus oligocaenica ANDREÁNSZKY, 1962 (Plate VII: 1-3) Alder leaves are quite common and variable in size and shape in EWU. They essentially belong to the group of Alnus nostratum UNG. complex, which includes elongate to broadly ovate leaves with eucamptodromous to semicraspedodromus venation and finely serrate to almost entire margin. We adhere to the ANDREÁNSZKY'S species because the populations from EW differ from the type of A nostratum often having forked secondaries and an almost entire margin. The type-specimen of A oligocaenica (MM 78.01.1) is an extremely small but the whole suite (ascribed by ANDREÁNSZKY 1966 to Alnus cf. sporadum UNG. var. phocaeensis SAPORTA - textf. 25, MM 64.23.1, A cf. nepalensis DON, - textfigs. 22-24, BP 67.68.1, MM 83.371.L, BP 67.67.1, Rhamnus cf. purshiana DC textf. 89) is connected with transitions. Some more slender forms, which are strongly serrate, recall A. gaudinii (HEER) KNOBL. et KVACEK. Infructescences of alder occur sporadically in EWU (BP 71.428.1, sub Alnus sp. in ANDREÁNSZKY 1966, textf. 27). They are rather small, unlike those associated with A. gaudinii elsewhere. Another type of bigger cones mentioned by Andreánszky (1966: 42) from EWM has not been available. According to the description it may not be excluded eventually that it will turn out to be a cone of Sequoia couttsiae. MYRICACEAE Myrica longifolia UNGER, 1850 (Plate VIII: 1) Avery common type of leaves with finely and widely seerate margin, partly very narrow (0,4 mm) identified as M. angustissima WATELET, partly wider, but always linear, longly cuneate at the base, is met with in EWU, quite rarely in EWM (MM 64.203.1) and EWL (MM 61.945.1, 61.966.1, 61.976, 64.84.1, 64.120.1). ANDREÁNSZKY unjustly rejected this name in view of the homonymous M. longifolia TEYSM. et BINN., which was published later and cannot endanger the usage of M longifolia (Dr. S. G. ZHILIN, pers. communication). The differentation of fragmentary materia! between M. longifolia and Engelhardia orsbergensis (WESSEL et WEBER) JÂHNICHEN, MAI et WALTHER is sometimes made difficult when detailed marginal venation is not preserved.
