Nagyipollis, a new pollen Fgen. from the Hungarian lower eocene (dedikált példány) [antikvár]

NAGYIPOLLIS, A NEW POLLEN FGEN. FROM THE HUNGARIANLOWER EOCENE(Palynologic investigations on the Lower Eocene layers in the surrounding country of Iszkaszentgyörgy. II.)ByM. KedvesInstitute for Botany of the University, Szeged, Hungary (Dir.: Prof. Dr. P. Greguss.)About fossile spores and pollens of the Lower Eocene layers of the surroundings of Iszkaszentgyörgy detailed data (including descriptions of several new species) will be published in the following number of Acta Biol. Szeged. In this short paper a new pollen form-genus containing 1 species is described. This pollen has a significancy from the point of view of pollen-morphology and stratigraphy. It is to be expected that this new pollen will be one of the suitable level-indicators of the Halimba-type pollen complexes of the Hungarian Lower Eocene (Sparnatien) layers.NagyipoIIis n. fgen.Fgen. type: NagyipoIIis globus n. fsp.Diagnosis: These pollens have three colpi. Each colpus has an aequatorial poms and in the vicinity of the poles several additional ones. Maximal number of pores is 9, 3 on each colpus. The minimal number of pores is 4, in most cases 5.Derivatio nominis: the name proposed for the new genus is derived from the name of Dr. E. Nagy, who is a prominent investigator of the pollens of the Hungarian Terciere.Note: no pollens with a similar morphology are described till now.NagyipoIIis globus n. fsp.Diagnosis: Ellipsoide, nearly globose pollens. Maximal diameter about 2030 /Í. Thickness of exine 1,83 /.i. Ectexine and endexine has roughly the same thickness. Structure of the surface is very marked: granulated sometimes verrucated. Height of the structural elements not more than 1 generally less. The colpi often fuse on the poles, so the two outside colpi run parallel with the contour. Width of the colpi 12,5 /t. They considerable widen above and below the pores but do not surround them entirely. The exopores are circular; diameter
