NEW PLATANACEOUS INFLORESCENCE ARCHARANTHUS GEN. NOV. FROM THE MAASTRICHTIAN-PALEOCENE OF THE AMUR REGION

Abstract

A new monotypic genus, Archaranthus gen. nov. (Platanaceae) with A. krassilovii sp. nov. as its type species, is erected for staminate inflorescences from the Maastrichtian-Paleocene deposits of the Amur Region on the basis of their microstructure. Leaves associated with the inflorescences are typical of Platanus. The existence of Platanus in the Cretaceous is discussed.
