An almost intact leaf covers the entire surface of a drilling core (diameter of 8.5 - 7.5 cm). The leaves are simple, mainly ovate in outline, with entire, non-lobate margin. The basis of the leaf is cordate or rounded, generally asymmetrical. The three basal veins and the secondary veins are connected with each other in a looplike manner. The secondary veins are branching off from the midvein at intervals of 2.2-2.5 cm. The species occurs in warm-temperate climate, from humid to swamp biotopes. It was probably a bush or rather small, arboreal plant preferring shady envi-
