66 Engelhardia, Castanea/Castanopsis, Quercus (including Quercoidites henrici), Caprifoliaceae, Rosaceae, and Cornaceae become signifi cant. MUŻAKÓW SERIES This section (L2) covers samples from the profi le Legnica 33/56, taken from clays of the depth 100.0–75.5 m (Nos. 23–4). The highest values of Poaceae (in one sample even 70%) and regular appearance of Graminidites bambusoides (up to 2–5%) are characteristic features of this section. Moreover, grasses are accompanied by such herbs as Cyperaceae (up to 2%; mainly of Cladium type), Asteraceae, Lythraceae, and Sparganium. Ferns are numerous and represented by Polypodiaceae s.l. (max. 50%) and Osmunda (up to 6%), as well as single spores of Cya thaceae/ Schizeaceae, Lycopodiaceae, and Toroisporis. Frequency of the palaeotropical element decrease radically. The palaeotropical taxa are represented by single sporomorphs (Tab. 1), reaching 2–4%. The warm-temperate taxa (predominantly swampy and riparian ones) prevail and are represented by Taxodiaceae/ Cupressaceae (max. 65%), Alnus (up to 70%), Salix (up to 12%), Ulmus/Zelkova, Betula (up to 10–12%), as well as Pterocarya (max. 8%), Quercus (up to 5%), Carya (up to 2%), and Acer. Pollen grains of shrubs (Ericaceae, Cyrillaceae/ Clethraceae and Ilex) and spores of Sphagnum are encountered sporadically. In samples from the lower part of this section (100.0–97.6 m) sporomorphs are badly preserved. In addition, some dinofl agellate cysts (max. 72 cysts = 20% in sample No. 19) and linings of foraminifers are present. HENRYK SEAM This part (section L3) contains samples from the profi le Legnica 33/56 – depth 75.0– 74.0 m (Nos. 3–1) and Legnica 41/52 – depth 91.8–89.3 m (Nos. 19–13), taken from brown coal and coaly clays. In this section the representation of the palaeotropical taxa becomes signifi cant again (Tab. 1). Relatively high percentages of Tricolporopollenites pseudocingulum (max. 4%), Quercoidites henrici (up to 2%), Araliaceoipollenites edmundi (up to 3%), Tricolporopollenites fallax (up to 3%), T. liblarensis (up to 2%), Ilexpollenites iliacus and I. margaritatus (together up to 17%), Castaneoideaepollis pusillus (up to 2%), and Symplocoipollenites (up to 3%) are noted. Frequency of the arcto tertiary taxa – Taxodiaceae/Cupressaceae (max. 40%), Sequoiapollenites (up to 30%), Pinuspollenites + Cathayapollis (up to 15%), Nyssapollenites (up to 18%), and Alnuspollenites verus (up to 16%) are still high. Pollen grains of Myricipites + Triatriopollenites rurensis, Cyrillaceae/ Clethraceae and Ericaceae are noted in quantities of a few per cent. The role of spores of Polypodiaceae s.l. (max. 40%), Osmunda (up to 18%) and Sphagnum (up to 2%) is signifi - cant, whereas such aquatic and swamp plants as Butomus, Sparganium, and Cladium, as well as fresh-water phytoplankton (Tetraporina and Ovoidites) occur sporadically. In addition, some moss spores, fungi and fragments of plant tissues (mainly wood, epidermis and stomata) are present. POZNAŃ SERIES, GREY CLAY HORIZON This section (L4) covers samples from the profi le Legnica 41/52 – depth 85.5–77.0 m (Nos. 12–1), taken from grey clays, as well as Komorniki 97/72 – depth 78.8–77.2 m (Nos. 9–1), taken from grey clays with two thin layers of lignites. This part differs from the above-mentioned one in lower frequency of taxa of high climatic requirements (Tab. 1). In the Legnica profi le these palaeotropical taxa reach max. 1–2%; only Ilex reaches 5%. In the Komorniki profi le these percentages are even lower – only a few pollen grains of Tricolporopollenites pseudocingulum, T. fallax, Araliaceoipollenites edmundi, Quercoidites henrici, Reevesiapollis triangulus, and Sapotaceae are present. The dominance of the arctotertiary element is well seen. High percentages of Taxodiaceae/Cupressaceae (max. 45% in the Legnica profi le and 65% in the Komorniki profi le), Alnipollenites verus (50% and 18% respectively in two abovementioned profi les), Nyssapollenites (25% and 3% respectively), Pinuspollenites + Cathayapollis (35% and 25% respectively), as well as Sequoiapollenites (18% and 5% respectively) are noted. In relatively high quantities appear also riparian taxa: Carya (up to 10%), Salix (up to 6–8%), Ulmus (max. 6% and 2% respectively in two above-mentioned profi les), Celtis (up to 4%), and Pterocarya (up to 2%). In addition, pollen grains of Fraxinus, Juglans, Quercus, and
