Cordiaceae wood from the Miocene sediments of northeast India and its phytogeographical significance.

Summary: The order Boraginales of the Lamiids clade encompasses a diverse group of plants that currently has a global distribution. Its fossil record is scanty. Herein we report a fossil wood of Cordia L. of the family Cordiaceae from the Tipam Sandstone (late Miocene) sediments of Assam, northeast India. This finding not only throws light on the phytogeography and diversification of the Cordiaceae, but also provides valuable insights into the Neogene vegetation of the region. [ABSTRACT FROM AUTHOR]
