It flowering from July to August, and fruiting from September to November. The morphological variations of the leaves, flowers and fruits and the geographical significance of the species are discussed. The discovery of new distribution in Henan is important significance on phylogenetic evolution, migration and medicinal plant resources development of genus Metapanax.
