Leaves elongate, entire-margined, 70–110 mm long and 15 mm wide, midrib straight, gradually narrowing towards the base apex, secondary veins thin, long ascending and looping, intersecondaries ending in tertiary veins that form a polygonal network. Abaxial cuticle moderately papillate, reflecting brachyparacytic stomata.

D i s c u s s i o n. This fossil species was at first compared with Laurophyllum villense (WEYLAND et KILPPER) KVAČEK, 1971 but later recognized as an independent fossil species ( Bůžek et al. 1976), widely distributed at Markvartice, outside the Bohemian Massive also found in Hesse (Flörsheim – Kvaček 2004, as Laurophyllum cf. villense ).
