Abstract

Characteristics of FERTILE ORGANS of a fern, MARATTIOPSIS ASIATICA Kawasaki, and morphologic features of their in situ PUNCTATOSPORITES SCABRATUS spores, from the Shemshak Formation, northeast of Shahrud, are investigated and compared with similar taxa reported from Iran and elsewhere. MARATTIOPSIS ASIATICA compared with other species of this taxon is distinguished by its possession of comparatively more crowded veins and longer synangia. The linear synangia are composed of two valves attached on secondary veins of the pinna margin. Each synangium is made up of two laterally joined long strips. Each sporangium contains a large number of relatively small, ±elliptical, bilateral, granulate, monolete spores which can be positively ascribed to the dispersed PUNCTATOSPORITES SCABRATUS.
