Studies in the Glossopteris flora of India - 9. A male fructification bearing monolete spores from the Lower Gondwana of India

Abstract

A new type of male fructification is described from the Raniganj stage. It consists of a long, cylindrical, stalked perhaps fleshy axis on which are embedded exannulate, most probably sessile sporangia. Sporangia contain large number of bilateral monolete spores. Spore wall shows parallel ridges or longitudinal lines on the distal surface.
