摘要: 通过对采自黑龙江省小兴安岭,张广才和完达山地区的龙牙楤木的主要分类学特征珠数量分析,发现此区域的该物种具有明显化为两个类群的趋势,一类属于原变种A.elata var.elata,另一类新组合变种A.elata var.mandshurica(Ruper.et Maxim.) W.H.Ye,初步说明了本区域龙牙Song木种群分化的基本特点。

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.).
