A new seed species of Illicium (Illiciaceae) from the Miocene-Pliocene of northeastern Tennessee, USA.

A new fossil species of Illicium is identified from 10 well preserved fossil seeds collected from the late Miocene-Pliocene Gray site, northeastern Tennessee, USA. The external morphology observations along with the testa anatomy comparison confirm an affinity with Illicium. The fossil is characterized by features such as obovoid in shape and seeds slight lateral flattened with obliquely truncated hilar. Further comparisons with published fossil Illicium seeds supports that the present fossil represents a new species, with a close affinity to the Old World species of Illicium. The discovery of Illicium from the late Neogene southeastern US adds extra evidence of the strong eastern Asian aspect of the Gray fossil flora.
