The Eren Basin of North China is a lage continental basin extending from
107°30'to 119°10'E longitude and from 42°to 45°45'N latitude with an area
of 100 000km2, in which the Mesozoic especially the Lower Cretaceous strata
are completely developed. In this paper, 14 genera, 46 species of fossil
angiospermous pollen found from the Early Cretaceous are described in
the Chinese text, among which 2 new genera (Songipollis gen. Nov.and Xuipollis
gen. Nov.) and 15 new species are described in the English Summary, with
9 species particularly described in greater detail. In this region, three
angiospermous pollen zones are distinguished and five evolutionary stages
of angiospermous pollen in Early Cretaceous are suggested, with a discussion
on some related problems
