Genus Laurophyllum GÖPP., 1854  

Laurophyllum cf. acutimontanum MAI, 1963 Pl.   1, Fig. 7

M a t e r i a l. 12 incomplete simple leaves and fragments, impressions PA 1623, PA 1650, PA 1662, PA 1665, PA 1679, NM-G 12808.

D e s c r i p t i o n. Leaves lanceolate to elongate, up to 69 mm long and up to 18 mm wide, apex not preserved probably shortly attenuate to acute or blunt, base cuneate with fragmentary petiole (up to 7 mm), margin entire, venation brochidodromous, midrib straight, secondary veins thin, alternate, at 40° to 60°, looping, tertiary veins alternate perpendicular, straight to sinuous, venation of the higher orders regular polygonal reticulate, poorly preserved.

R e m a r k s. The lauroid leaves with entire margin and brochidodromous venation are typical lanceolate to elongate in outline and in gross morphology match slender leaves of Laurophyllum cf. acutimontanum   , which are common elements of late Eocene to Oligocene floras in Central Europe, e.g., Staré Sedlo, Bechlejovice, Kundratice, Suletice-Berand, Holý Kluk, Seifhennersdorf ( Kvaček   and Walther 1995, 1998, 2004, Knobloch et al. 1996, Radoň et al. 2006). However, the lack of epidermal structure does not allow for a clear assignment because the foliage of Laurophyllum pseudoprinceps WEYLAND et KILPPER   and Laurophyllum medimontanum BŮŽEK, HOLÝ et KVAČEK   have similar leaf morphology and co-occurred with Laurophyllum acutimontanum   at Suletice-Berand, Kundratice and Bechlejovice ( Kvaček   and Walther 1995, 1998, 2004).
