Opis:
The article presents the composition of the dendroflora in a historic park surrounding the castle in Szamotuły. In total 465 specimens of woody plants were inventoried (51 taxa of 37 species in 21 families). Most of them were native, angiospermous trees of the apophyte and spontaneophyte groups. In the park there are three specimens of Taxus baccata, registered as natural monuments. The age of more than 100 trees was estimated at over 100 years. The trunk circumference of more than 60 trees exceeded the minimum value assumed as a criterion of categorisation as a natural monument.

Opis:
This article presents the results of a study on seed coat micromorphology and epicuticular structure of Ginkgo biloba cultivars. The micromorphology of the seed coat of 10 cultivars and one clone of female G. biloba were analysed. The taxa differed in the size and shape. Homogeneous epicuticular wax deposited in the form of wax tubules on the sarcotesta and sclerotesta surfaces. There were great differences in wax between the outer and inner layer of the sarcotesta. In the endotesta wax was diversified in the form of tubules, platelets or it was mixed. The article includes descriptions and illustrations of several micromorphological features which have not been published previously. The results of the SEM and LM investigation confirmed the taxonomic significance of the micromorphological traits in the Ginkgo genus. In the seeds many characters are present in of all the taxa and may be typical of Ginkgo.

Opis:
The present study was conducted to illustrate the micromorphology of mature sporangia and pollen grains of four Ginkgo biloba cultivars: ‘Horizontalis’, ‘Lasiocarpa’, ‘Pragensis’ and ‘Tubifolia’ and is a continuation of earlier investigations on this subject. The sporophylls bear typically two pendulous sporangia, whereas three were found in one cultivar. The sporangia varied in shape from oval, elliptical elongate to boat-shaped and dehisced along a longitudinal slit. The sporangial walls are multilayered. The sculpture of the sporangium is rugose covered with wax crystals (tubules) and the endothecium shows clearly visible fibrous thickening on the wall. The pollen grains are monosulcate, the non-apertural surface is irregularly ridged (striate) or rugulate, with perforations and the germinal aperture (furrow) is covered with verrucae. The current study did not differentiate significantly four cultivars based on sporangia and pollen morphology. The micromorphological traits may be useful for identification and classification of fragments of fossil sporangia and pollen grains.
