New platanaceous genera are described based on micromorphology of a capitate infructescence (Kunduricarpus Kodrul, N. Maslova, Tekleva & Golovneva) and staminate inflorescence (Kundurianthus Kodrul, N. Maslova, Tekleva & Golovneva) from the Campanian of Amur Region, Russia. The presence of common characteristic features implies possible affinities of these reproductive organs to the same plant.
