A new species, Platimeliphyllum valentinii, is described from the Paleocene of the Amur Region on the basis of macromorphological and epidermal characters. It was shown that leaves of Platimeliphyllum N. Maslova associate with two fundamentally different types of reproductive structures: platanaceous Archaranthus N. Maslova et Kodrul and Bogutchanthus N. Maslova, Kodrul et Tekleva, which combines characters of the Platanaceae and Hamamelidaceae. The higher evolutionary stability of leaf structures in comparison with reproductive organs is discussed.
