Material; 86.146.1. Description: 3.7 cm long, 1.6 cm width small fragment of the pinnate leaf have been found. The fragment is badly preserved. The leaflets were attached to a thick rachis. The leaflets are dissected, they are attached to each other at the median third forming an uniform lamina, with only their apices standing out. The venation forms a network; there is thick midvein in the middle of each leaflet, from which curved venation arises both on the right and left sides. Discussion: The species is known in Hungary from the Late Oligocène to the Middle Miocene. It was reported from the locality Eger, Wind - brickyard, from the upper strata (Andreánszky 1966) as Lastraea cf. oeningensis. It is absent from the other Egerian floras of Hungary. It is more frequent in the Miocene, (e. g. Ipolytarnóc: Hably 1985). In Europe it is known from the Paleocene to the Pliocene.
