Abstract

Ten localities of seven Permian fossiliferous horizons of the Boskovice Furrow have been studied. The new excavations yielded 1531 Permian specimens that contributed to the knowledge of floral assemblages of individual fossiliferous horizons. 20 species are new for fossiliferous horizons and 15 species are new for the Boskovice Furrow: Pecopteris cf. bredowii, Remia pinnatifida, Odontopteris lingulata, Neurocallipteris gallica, N. planchardii, Rhachiphyllum aff. curretiensis, ?R. subauriculata, Dicranophyllum longifolium, Culmitzschia angustifolia, Hermitia arnhardtii, H. germanica, H. rigidula, H. schlotheimii and bifurcated leaves of uncertain affinity (Lausberg - Kerp 2000). Meso- to xerophilous flora is dominated by conifers. The most common conifers in the so called "walchian shales" are Otovicia hypnoides and Culmitzschia parvifolia. Other very common species in different lithologies are Ernestiodendron filiciforme and Walchia piniformis. Conifers represent 70 % of Permian floral assemblage, whereas the stratigraphically important callipterids form only 3 % of the floral assemblage. Autunia conferta dominates among callipterids. Other plant groups - sphenopsids, ferns and other pteridosperms - are extremely rare. Cordaites are common on some localities. These assemblages are characterised as meso- to xerophilous.
