Abstract

The paper records four fossil woods, viz., Koompassioxylon elegans Kramer, Baubinia tertiara sp. nov., Bischofia palaeojavanica Awasthi and Laurinoxylon naginimariense sp. nov. from the Tipam sandstone of Assam and Nagaland. These show close resemblance with the woods of extant genera, viz., Koompassia, Baubinia, Bischofia and Lauraceae, respectively. Occurrence of Koompassia in the Indian and southeast Asian Neogene sediments provides further evidence of a close phytogeographical link between Indian subcontinent and Southeast Asia.
