Abstract

A carbonized spore-bearing fructification under Bosea indica gen. et sp. nov. has been described here from Nidpur beds. It consists of an axis with microsporophylls arranged in opposite or sub-opposite order. The microsporophyll is flattened and elongated, along the margin of which sporangia are borne pendant on its under surface. Each sporangium contains Weylandites-type of spore.

Bosea indica, in its sporophyll cuticle, resembles Lepidopteris indica Bose & Srivastava. In its spore-type, it is distinct from all the so far known pteridosperrnic fructifications.
