Abstract

"On the basis of its anatomical structure, a new species of Araucarioxylon is described. It is characterized by growth rings, tracheids of araucarioid 1-4 seriate radial pitting, 2-20 araucarioid or cupressoid pits in the cross fields, and parenchymatous homocellular rays, 25% of which are partly biseriate and 1-21 cells heigh. Comparing its secondary xylem, the closest species seem to be: Dadoxylon manieroi Krausel et Dolianiti, D. gondwanense Maithy, D. adhariense Prasad, Araucarioxylon tschertense Lepekhina and Polisolenoxylonjhariense (Surange et Sah) Maheshwari. Details of anatomy of this wood and associated mega and microflora suggests relationships with Glossopteridales."
