ANGIOSPERMAE inc. sed. "Elaeocarpus" europaeus ETTINGSHAUSEN, 1869 (Plate IX: 4) A single leaf compression from EWL (MM 66.137.2 - orig. ANDREÁNSZKY 1966, 94. textf. 88) is well comparable with a characteristic form of unknown systematic position occurring in the North Bohemian Oligocène floras. "Ficus" latsonoides ANDREÁNSZKY, 1966 (Plate III: 2) Orbicular leaves with palmate venation, slightly asymmetrical, longly petiolate rather suggesting Malvalean affinities or even Menispermaceae. In spite of numerous attemps we have not been able to prepare cuticles from the carbonized lamina often preserved on the type-material. The most complete specimen is suggested to be the lectotype (MM 78.07.2 - Andreánszky 1966, textf. 71). About 20 other specimens are available at MM, all from EWL. The fragments from EWM (ANDREÁNSZKY 1966, textf. 70) are questionable. "Quercus" cruciata AL. BRAUN, 1851 The record from EW was referred to as Quercus gigantum Ett. (ANDREÁNSZKY 1966. textf. 46-49, NAGY & PALFALVY 1963, pi. 7, f. 1, 2) and revised in a separate paper (KVACEK & WALTHER 1981). About 10 specimens are available at MM from the EWL. This plant is surely a thermophillous element but no exact match among recent plants can be suggested. "Rhamnus" warthae HEER, 1872 (Plate XII: 1,4) One of the commonest leaf form in EWU was described or referred to under very different names. ANDREÁNSZKY (1966) identified it with Symplocos (e.g. Symplocos cf. phanerophlaebia MERR. 1. c. textf. 95) but also as Styrax cf. japonica SIEB, et ZUCC. (1. c. textf. 76) or Elaeocarpuspalaeolanceolatus KOLAKOVSKD (1. c. textf. 87). The largest specimens have widely cuneate base and acuminate apex and attain at least 15 cm in length. Smaller forms are lanceolate to oblanceolate. All variable forms are connected with the same type semicraspedodromous venation, which form steep loops of widely spaced secondaries. The secondaries and tertiaries are fine but very distinct forming characteristic aréoles along the margin. Tiny side veins enter the marginal spiny teeth that can be very indistinct. According to the character of the impressions showing distinct venation but only little quantity of coaly matter the leaves were obviously chartaceous. Their mass occurrence in the riparian vegetation in EWU and also at Jiu Valley (see STAUB 1887, sub Rhamnus warthae, pi. 38, f. 1, 2, Juglans heerii, pi. 27. f. la, Laurus primigenia, pi. 28, f. 6, pi. 29, f. 1, pi. 34-35, f. Id) recalls a similar association of the Lower Miocene of North Bohemia. The Miocene riparian forest there included masses of leaves otRubus merianii (HEER) KOLAKOVSKLl. Therefore, we tried to match "Rliamnus" warthae with some Rubus species and indeed have found representatives with simple leaves belonging to the sect. Sozostyli FOCKE from southern China and other subtropical SE. Asia that recall our fossils (e. g. R. mairei LÉVEILLÉ). They differ by at least the apical craspedodromous secondaries, though. "Talauma" egerensis ANDREÁNSZKY, 1955 (Plate XII: 3, 5) Large oval to longly ovate-obovate entire-margined leaves with broadly cuneate base and acuminate apex up to 6 cm wide and more than 15 cm long occur sporadically in EWU. Very regular camptodromous venation looping along the margin and obliquely forked tertiary veins offer little evidence as to the affinities
