Abstract

The present work is based on five specimens of fossil Cycadean stems collected from the Rajmahal hills, Bihar. One of the stems is especially interesting because it has got a Williamsonia type of flower attached to it at the apex. These stems have been compared with the other fossil Cycadean stems and Protocyathea rajmahalense Jacob.
