Abstract

The two fossil dicotyledonous woods, Gondwanoxylon kathotiai (Saksena, 1963) and G. ghiarii (Saksena, l.c.). have been re-investigated here from their type slides. On re-description they have been found to resemble the genus Ailanthus of the family Simaroubaceae, and therefore referred to the genus Ailanthoxylon Prakash (1959). The species, Gondwanoxylon kathotiense, is found to be identical to the already described Ailanthoxylon indicum Prakash whereas G. ghiarense, an entirely new species of Ailanthoxylon, is re-described under the revised name Ailanthoxylon ghiarense (Saksena) comb. nov. In the later part is given a critical review of the hitherto described species of the genus Ailanthoxylon. Because of no essential differences the species A. scantiporosum Ramanujam (1960). A. mahurzariense Shallom (1961) and A. pondicherriense Navale (1964) have been united here under the name Ailanthoxylon indicum Prakash (1959), which has priority over the rest.
