Revision of some dicotyledonous woods from the Tertiary of south India

Abstract

Five fossil dicotyledonous woods, namely Guttiferoxylon indicum Ramanujam (1960), Celastrinoxylon dakshinense Ramanujam (1960), Ingoxylon sahnii (Ramanujam) Miiller-Stoll & Madel (1967), Dalbergioxylon antiquum Ramanujam (1960) and Dipterocarpoxylon cuddalorense Navale (1963b) described from Murattandichavadi near Pondicherry have been reinvestigated. Of these, the first two species are identical with Ailanthoxylon indicum Prakash (1959) from the Deccan Intertrappean Series of Mahurzari near Nagpur. The occurrence of these two woods in the Cuddalore Series has been considered doubtful. The remaining three species show identity with the already known species Pahudioxylon sahnii Ghosh & Kazmi (1961) from the Tertiary of Tripura, Euacacioxylon bharadwajii (Navale) Miiller-Stoll & Madel (1967) and Terminalioxylon grandiporosum Ramanujam (1966) from the Cuddalore Series near Pondicherry respectively.
