Abstract

The name Salmioxylon rajmahalense is here adopted for the petrified wood Homoxylon rajmahalense Sahni, as the generic name Homoxylon was already used by Hartig in 1848 for a different type of fossil wood belonging to the Abietineae.

Two recently collected large specimens of Sahnioxylon rajmahalense, throwing further light on the anatomy of the secondary wood, are briefly described. Diagnosis of the genus Sahnioxylon is given based on all the available information.

A new species of Sahnioxylon, S. Andrewsii, is described on the basis of a specimen from Kulkipara near Amrapara, in the Rajmahal Hills, Bihar. Comparisons of the species have been made with Sahnioxylon rajmahalense, Cycadeoidea, Raumeyia and Colymbetes.
