Abstract

A petrified Cycadinorachis omegoides is reported from Sonajori in the Rajmahal Hills, Bihar. The number of bundles in the omega gradually reduces while the distinction of centripetal and centrifugal xylems increases towards the apex of the rachis (leaf). The ground tissue possesses mucilage ducts. The lamina has parallel veins and a more or less homogeneous mesophyll. Tracheids possess scalariform and contiguous bordered pits. The relationship of Cycadinorachis with allied extinct and extant plants is discussed.
