2002a Osmunda lignitum (GIEBEL) STUR ; Kvaček, p. 221, pl. 1, fig. 10.

Incomplete pinna 10 mm wide and exceeding 35 mm in length, coarsely toothed on margin according to the pinnules, midrib straight, pinnules short elliptic, acuminate, max. 7 mm long and 4 mm wide, entire-margined, at an angle of 40°, midribs straight to slightly S-shaped, secondaries free, stretching towards the pinnule apex, simple or forked, 5–6 on each side of the midrib.

R e m a r k s: This typical Paleogene European fern ( Barthel 1976) was recovered only rarely in the České středohoří Mountains (e.g., Kvaček and Walther 1998). The single fragment from Kučlín is more delicate than most other records from Europe. Osmunda banksiaefolia (K. PRESL) KUHN. from East Asia was considered by Holttum the nearest living species.
