Abstract
The fossil plants of the Group Pentoxyleae collected from the Rajmahal Hills suggest an assemblage of small trees with multimorphic branches, polystelic vasculature and diploxylic bundles in leaves. Microsporophylls are radial, branched and have balloon-shaped microsporangia with monocolpate spores. Ovules originate directly from cone axis. Its relationship has been discussed with different groups of gymnosperms (Medullosales, Cycadales, Bennettitales, Ginkgoales, Coniferales and Gnetales) and angiosperms.
