New pollen species from the lower miocene of the Bakony mountain (Várpalota) of Hungary (dedikált példány) [antikvár]

NEW POLLEN SPECIES FROM THE LOWER MIOCENE OF THE BAKONY MOUNTAIN (VÁRPALOTA) OF HUNGARYByEsther Nagyhungarian geological institute budapest (Received November 10, 1961)Introduction I.Some samples originating from the bore-hole Nr. V. 133 in the vicinity of the village Várpalota in the Bakony in the western part of the Hungarian Central Mountains, were handed over to us for pollen-analysis by the geologist KÓkay. The samples of the sequence of the bore-hole originate from the Helvetian, the samples No. 1 and 2 from marine, sandy, sandstone deposits, the samples No. 37 from lacustrine clay layers found under the strate considered as marine Lower Helvetian. The base of this stratigraphic complex consists of upper Eocenic (Barton) marl (KÓkay, 1959). The samples contain peculiar, interesting flora-elements differing from our Helvetian material hitherto investigated, and noteworthy also in their botanical relationships suggesting some problems of nomenclature and taxonomy for consideration.The new species described were found together with a varied fossil plant community. In addition to the Conifers characteristic of the mountain forests (Pinus, Picea, Podocarpus, Tsuga, Dacrydium), mixed leafy forests from the foot of mountains (Acer, Tilia, Quercus, Castanea, Parrotia etc.) and, in the vicinity of the continental lake, Alnus, Betula and Salix species were represented. The species described are representative of tropical-subtropical floristic elements which differ from the Miocenic florae known up to now from Hungary.Since very few pollen analyses have been carried out as yet from the Miocene strata of the Bakony mountain, it would be of course a mistake to draw far-reaching conclusions from these few samples.It may be stated, however, that in the third sample (208, 3214, 2 m) containing a very rich floristic society, with Polyadopollenites várpalotaensis ^ n. sp. which refers to the genus Acacia also present, the form Alangiopollis ^ bargfoornianum (Table VII, Fig. 1718) described by Krutzsch occurred. According to this author, in Germany, this form is a member of the Lower Miocene and Upper Oligocene community (Geologic 11, H. 2. Berlin 1962).On the other hand, Malvacearumpollis bakonyensis n. g., n. sp. described by us, is found in the Oligocenic strata of Dorog (verbal communication of Rákosi). It seems probable that between the Upper Oligocenic and Lower
