- Abstract
Sturia amoena (Stur) Němejc is a Pennsylvanian adpression true fern known from the Charbonnière de Belle et Bonne (Belgium) and from the Radnice and Kladno-Rakovník basins (Czech Republic). This revision includes a detailed study of pinna and pinnule morphology, aphlebiae and reproductive organs. Interesting details of sporangia and in situ spores are described for the first time. The sporangia of Sturia amoena have an equatorial bi-triseriate annulus and yielded in situ spores of the Punctatisporites and Apiculatisporites types.
