Abstract: The key characters of the ligniferous species of Aralia, collected from Xiaoxingan Mountains, Zhangguangcai Mountains, Wandashan Mountains of Heilongjiang province, had been analyzed. With the analysis of LSR (Length of secondary rachis of the infloresoence) and LLP (Length of Leaflet petiole of the compound leaf), the specimens can be divided into 2 taxa. But there are some continuous variation and overlaps in these characters, so these 2 taxa can not be regared as independent species. It is reasonable to regard them as one species (A.clata), and put the taxon that is corresponded with the characters of A.mandshurica into A.elata, as a new combination variety. Therefore, the ligniferous species of Aralia in northeast of China, are identified and named as A.elata (Miq.) Seem. and A.elata(Miq.) Seem. var.mandshurica W. H. Ye(stat.nov.).
