Botanical resolution of some microstructures of nevyeli lignite, South India

Futher studies on the microscopic composition of Neyveli lignite, South-India have revealed that some microstructures show affinities to certain angiosperm taxa such as Guttiferae, Dipterocarpaceae, Leguminosae, Combretaceae, Euphorbiaceae, Palmae and Gramineae. The present paper records the xylotomical features of the newly recognized biostructures as seen in the polished surface sections, and their affinities to modern genera.
