A good frequency of pollen and spore taxa are recovered during the palynological study of the Bhavnagar Lignite of Gujarat. Pollen assemblage consist of 66 genera and 85 species. Of these, eight genera and 12 species are of pteridophytic spores, one genus of gymnosperms and 57 genera and 74 species of angiosperms. Amongst these, one genus and nine species are described as new. On the basis of abundance, the Bhavnagar palynoassemblage is divided into two cenozones in ascending order as Triplanosporites sinuous Cenozone and Arengapollenites achinatus Cenozone. Palynoflora suggests deposition of this lignite during Early Eocene period under warm humid tropical climatic conditions.
