Morphology of pollen grain was described for nine American persimmons (Diospyros virginiana L.) genotypes (DV-01 -DV-09) at the Institute of Biodiversity and Biological Safety of Slovak Agricultural University in Nitra using an electron microscope Carl Zeiss LS 15, and the microphotographs were taken. The measurement of morphometric parameters was carried out on 50 pollen grains from each genotype using the AxioVision Rel. 4.8.2.0 program. The measurements were made in micrometer (μm). The length of polar axis (P) and the equatorial diameter (E) of grain, P/E ratio were measured and their variation was compared among studied genotypes. The polar axis and equatorial diameter of pollen grains values were varied from 51.94 to 78.60 μm and from 23.00 μm to 42.71 μm, respectively. This study showed that there were significant differences among the genotypes in all measured factors. Pollen grains are radialsymmetrical, isopolar, tricolpate (with three sulcus). Exine surface is a bicomponent sculptural type with small perforate-undulate or wrinkled weakly perforate. Percentages of abnormal pollen grains ranged from 2.0 to 19.3% among the genotypes. It was noted that diversity of surface sculpturing of pollen grains in combination with shape and sizes of them enables to use complex of thin morphologic signs for Diospyros virginiana pollen identification.

Flowers of extant Quintinia are described in detail on the basis of field observations and serial microtome sections and compared with flowers of the Late Cretaceous Silvianthemum suecicum and Bertilanthus scanicus on the basis of new analyses of the fossil material. The analyses of both extant and fossil material also include synchrotron-based X-ray tomographic microscopy. The study shows that Quintinia and Silvianthemum/Bertilanthus have more features in common than previously recognized and strongly reinforces their earlier assumed close relationships. Among important characters linking the three genera are similar secretory hairs on the floral surface and pedicel; short sepals; free, quincuncial petals; broad anthers with small pollen sacs; 4-aperturate pollen (in Silvianthemum and Quintinia); postgenital union of the 3-4 apocarpous styles (in Silvianthemum and Quintinia); connection of the apocarpous carpel parts with the floral base; downward tapering ovary and locule(s); placentation on incomplete septa; and flask-shaped epidermal cells with a thin and long papilla on the carpels. Features observed in Quintinia, particularly the presence of bitegmic ovules and free petals, suggest that the apparent phylogenetic position with extant Paracryphiales (campanulids) needs further analysis. Bitegmic ovules are not known from other Paracryphiales or campanulids, and the presence of free petals is unusual in campanulids.
