Abstract

A new species Platimeliphyllum reznikoviorum N. Maslova is described from the Paleogene of Nizhnii Ashut locality (central Kazakhstan) based on the leaf macromorphological and epidermal characteristics. A capitate infructescence sharing characters of Platanaceae and some Hamamelidaceae was found together with the leaves. Small reticulate tricolpate pollen grains were found adhered to the carpel surface. The fossil leaves and reproductive structure are supposed to belong to the same plant. Fossil leaves attributed to Platimeliphyllum are associated with reproductive structures of various genera belonging to different families. Therefore we use the morphological classification for dispersed angiosperm leaves proposed by Krassilov (1979) to define the taxonomic position of this genus.
