ON SOME ASPECTS OF SYSTEMATICS AND EVOLUTION OF THE ENGELHARDIOIDEAE (JUGLANDACEAE) BY WOOD ANATOMY
Abstract. Some aspects of systematics by wood anatomy as well as wood anatomy specialization of the subfamily Engelhardioideae (Juglandaceae) are discussed. The age variation of wood anatomy over the radius of stem has been examined in the Oligocene Engelhardioxylon mameticum from Kamchatka (Russian...
