M a t e r i a l. 4 specimens, Líšeň-Neklež ( MB80 MB83 ) .

D e s c r i p t i o n. Incomplete pinnules 13 to 22 mm long by 8 to 10 mm wide, shortly elliptic, acuminate, margin entire, midrib straight to slightly S-shaped, secondary veins free, bending towards pinnule apex, simple or forked.

R e m a r k s. O. parschlugiana is known from many Miocene sites of Europe. It is typified based on material from the Early/Middle Miocene flora of Parschlug ( Unger 1847, Kovar-Eder et al. 2004). The pinnules are commonly known from the Early Miocene Most Formation (e.g., Bůžek 1971, Sakala 2000, Teodoridis 2006) and morphologically close to Blechnum dentatum (GÖPP.) HEER ( Kvaček and Hurník 2000) . Knobloch (1969: 55) reported this fern from Uhelná, Silesia, the Czech Republic. It has also been recorded from Arctic regions, Kazakhstan, Iran and elsewhere associated with Turgayan “Arcto-tertiary” leaf assemblages ( Kvaček and Bubík 2016).
