Matonidium cingulatum n. sp. from Kachchh, India

Abstract

Matonidium cingulatum n. sp. is based on detached sterile and fertile pinnae collected from three different localities in Kachchh. The specimens, in external features, resemble M. goepperti (Ettingshausen) Schenk described by Harris (1961), but they differ from the latter in the details of spore character. In M. cingulatum the spores have a narrow cingulum and they do not show any thickening of exine around the trilete mark.
