A Glossopteris bearing Sori-Sike Structures

Abstract

IT had been indicated by Feistmantel¹ that some species of Glossopteris bear sori in one of the following patterns, namely, in longitudinal rows (Indian materials), along the veins (Australian materials) and along the margin (Indian materials). Unfortunately, these structures were not well recognized in the subsequent literature on fructifications assigned to Glossopteris. Recently, an undetermined species of Glossopteris, bearing sori-like bodies (Fig. 1) as described by Feist-mantel^1,2, has been collected from the Middle Permian (Barakar) in the Central Province of India. The specific determination of the specimen was not possible because its upper half only is preserved and the venation (excepting the midrib) is not always distinct. The rock bearing the fossil is a piece of soft greyish shale.
