CONIFERAE PINACEAE Pinus sp. div. (Plate II: 1) Little can be added to ANDREÁNSZKY'S treatment of this genus (ANDREÁNSZKY 1966: 20-22). The cones he figured (1. c. figs. 3 and 4) have not been found at MM. Another specimen (MM 64. 1089.1) from EWL, represents a slender, badly preserved cone of the subgen. Strobus, as it is shown by a dorsal mucro preserved on the conescales of the cone apex. Similar pine cones have been known from the Paleogene of Europe, e.g. from the Oligocène of southern France (SAPORTA 1865, pi. 3, fig. 1 E sub Pinuspalaeostrobus ETT.). New collections from EWM include numerous specimens of pine needle leaves covering bedding planes. They lie parallel each other, arranged by current, probably joined into fascicles of two. In EWU the needle fragments (fascicles of two, three and five needles) occur rarely (two specimens at BP). They are referred to by NAGY & PALFALVY (1963, pi. 5, f. 1) as Pinus cf. tuzsoni NOVAK, P. palaeostrobus ETT and P. taedaeformis (UNG.) HEER. These authors record pine seeds (1. c. pi. 5, f. 8). TAXODIACEAE Sequoia couttsiae HEER, 1863. (Plate II: 4, 5) Female cones up to 2 cm across, partly with visible resin canals, showing peltate cone scales as big as 8 mm across, occur quite often in EWU. They are partly attached, partly associated with slender twigs with appressed, helically arranged small scale leaves. This foliage was erroneously identified as Glyptostrobus (ANDREÁNSZKY 1959, NAGY & PALFALVY 1963). A detached seed of the Sequoia-xypt (MM 61.211.1) has newly been recovered in the association of the cones. We agree with CHANDLER (1962) to range this species to Sequoia rather than to Athrotaxis because the seeds of the latter are different. Sequoia couttsiae represents certainly a species very distant from the living S. sempervirens. CUPRESSACEAE Tetraclinis sp. (Plate II: 6) Cones and detached cone scales of the Tetraclinis-Xype form a rare accessory elements of EWU (Nos. MM 56.1390.1, BP 56.1391.1, 67.141.1, 71.1276.1). They have been identified as Callitrites brongniartii (ANDREÁNSZKY 1955, pl. 1, f. 3) but we are not informed to what kind of foliage they belong. PALFALVY (in NAGY & PÁLFALVI 1963) reports both species as T. salicornioides (UNG.) KVACEK (sub Calocedrus salicomioides (UNG.) PALFALVY comb, illegit.) and T. brachyodon (BRONGN.) MAI et WALTHER (sub Tetraclinis brongniartii ENDL. 1. c. pi. 5, f. 7,9) but we were unable to verify both the records in MÁFI. ? CEPHALOTAXACEAE (Plate II: 2) A single completely pyritized compression of a long-leaved shoot from EWL (MM 64.71.1.) was identified by ANDREÁNSZKY (1966, textf. 5) as Sequoia langsdorfii (BRONGN.) HEER. Although it recalls superficially Taxodiaceae it differs much from the true Sequoia abietina (BRONGN.) KNOBLOCH (syn. S. langsdorfii) by its sharply mucronulate leaf tips (revealed by additional preparation). The lack of cuticular structure prevents us to give a more satisfactory identification. Such kind of foliage (the length of leaves attainig 2,5 cm) is
