Two new species of Dadoxylon, viz. Dadoxylon gondwanense and Dadoxylon kharkhariense are described. The former is characterized by radial pitting 1-5 seriate, contiguous, alternate and subopposite; cross-field pits 2-8; medullary ray uniseriate and biseriate and 1-43 cells high. The latter wood Dadoxylon kharkhariense is characterized by the presence of pitting both on the radial and tangential wall of the tracheids, 1-3 seriate, alternate, sub-opposite and opposite; contiguous or separate, sometimes in distinct groups of 2 or 3 pits; crossfield pits 2-5 (7); medullary rays uniseriate, rarely biseriate.
