The locality of Odrowąż is an Early Jurassic section in central Poland, with a taxonomically relatively poor flora. The available material is composed of both macro- and microremains. The macroremains, represented by 720 specimens (491 suitable for study), consist mainly of leaves, shoots, rhizomes, as well as male and female cones and fragments of other fructifications. sphenophytes, pteridophytes, pteridosperms, bennettites, cycads, ginkgophytes, conifers are represented by single taxa, only ferns are more diverse. The material is dominated by the conifer Hirmeriella muensteri (schenk) Jung and the benettite Pterophyllum alinae Barbacka sp. nov. Taxonomically, the ferns are the most diverse group (five species belonging to five genera). Most of the plants show adaptations to wet conditions, which corresponds well to the proposed sedimentary environment, a river plain. The complete material shows, however, that the floral remains originated from a wider area situated along the river and on its banks. One new genus, Odrolepis, three new species, Odrolepis liassica, Pterophyllum alinae, Paracycas minuta, and one new forma, Todites princeps, forma trilobata, are described. some forms are left in open nomenclature.

Studzianna well core (Triassic-Jurassic) from the Holy Cross Mts region were investigated. Fossil plants from the genus Neocalamites (Equisetales) were found mainly in the Triassic sediments. Fragments of Ginkgoales and Czekanowskiales and Coniferales were determined mainly from the Lower Jurassic. The Lower Jurassic microflora consists of sporomorphs from Bryophyta, Equisetales, Lycopodiales, Filicales from the family Cyatheaceae or Dicsoniaceae, Pteridospermophyta from Caytoniales, Ginkgoales or Cycadales or Bennettitales, Coniferales from the families Taxodiaceae, Pinaceae and Cheirolepidiaceae. Palynofacies have mainly terrestrial character and confirms earlier opinion (Karaszewski 1962, Pieńkowski 2004) of the prevailed terrestrial origin of the Lower Jurassic (Hettangian-Sinemurian) sediments from the Holy Cross Mts region.

Upper Triassic macroflora from Lipie Śląskie near Lublin in Poland was investigated. Five different morphological types of cuticulae dispersae were found. One type belongs to Lepidopteris ottonis (Goeppert) Schimper (Pteridospermae), an index species for uppermost Triassic. Other types probably belong to Coniferales e.g. Cheirolepidiaceae.

New macroflora remains were found from the Famennian strata (unit J) from the Kowala Quarry (the Holy Cross Mts., central Poland). Palynological research indicates presence of the VF (Diducites versabilis-Grandispora famenensis) miospore Zone. Macroflora is very well preserved as many carbonized parts or imprints. Preliminary observations indicate that those remains can belong to genus Archaeopteris. This cosmopolitan genus has been earlier reported from Poland in the Sudetes Mts. from similar stratigraphic position.

Opisano makroszczątki roślin znalezione w osadach serii witowskiej. Zachowały się one w postaci odcisków w słabozwięzłych piaskowcach i mułowcach. Rośliny iglaste reprezentowane są przez gatunek Pinus cf. palaeostrobus (Ettingshausen) Heer oraz szczątki, których nie udało się oznaczyć. Wśród szczątków roślin dwuliściennych oznaczono liść gatunku Zelkova zelkovifolia (Unger) Bůžek et Kotlaba, liście rodzajów Fagus i Populus oraz owoc z rodziny Juglandaceae. Część okazów roślin okrytozalążkowych, których nie udało się bliżej oznaczyć, opisano jako „Leguminosae” sensu Berger oraz Dicotylophyllum. Rośliny jednoliścienne reprezentuje gatunek Spirematospermum wetzleri (Heer) Chandler oraz odcisk fragmentu liścia Monocotyledonae gen. et sp. indet. Skład oriktocenozy wskazuje, że w czasie sedymentacji osadów serii witowskiej w okolicach Witowa występowały lasy łęgowe oraz mezofilne w warunkach bardzo łagodnego klimatu umiarkowanego ciepłego. Obecność szczątków Pinus cf. palaeostrobus (Ettingshausen) Heer, Spirematospermum wetzleri (Heer) Chandler, Zelkova zelkovifolia (Unger) Bůžek et Kotlaba i przedstawiciela rodziny Juglandaceae oraz wyniki analizy pyłkowej wskazują, że wiek tej części serii witowskiej, z której pochodzą omawiane szczątki roślin odpowiada młodszemu neogenowi (późny miocen-pliocen).

Macroremains of plants (leaves, fruits, shoots) in the Witów Series at Witów us impressions preserved in poorly cemented occur and mudstones. Coniferous plants are represented by Pinus cf. palaeostrobus (Ettingshausen) Heer, and other, indeterminate remains. Remains of dicotyledons belong to species Zelkova zelkovifolia (linger) Buzek et Kotlaba, genera Fagus and Populus, and family Juglandaceae. There are also some dicotyledonous fossils ("Leguminosa" sensu Berger, Dicotylophyllum) whose systematic position is unclear. Monocotyledonous plant remains are represented by Spirematospermum wetzleri (Heer) Chandler and Monocotyledonae gen. etsp. indet. Composition of oryctocoenosis found points to presence of riparian and mesophytic forests, as well as mild, warm temperate climate during the period of origin of the Witów Series. Presence of taxa of Pinus cf. palaeostrobus, Spirematospermum wetzleri, Zelkova zelkovifolia and remains of Juglandaceae, as well as results ofpalynological investigations suggest Younger Neogene (Late Miocene-Pliocene) age of the Witów Series with plant remains.
