Study on numerical taxonomy of 15 species of Lonicera L.

Based on 37 morphological characters,15 species of Lonicera L.were studied by means of numerical taxonomic methods in this paper.The results were as follows:①Lonicera L.can be divided into two groups not by subgenus,but by Subsect.Subsect.Caerulea form a group,the other subsects form another large group;②The species of Sect.Coeloxylosteum naturally gathered together,which shows that the traditional classification is basically right;③Subsect.Caerulea had close relationships with other Subsects.of Sect.Isika,but it had not close relationships with the Subsect of Sect.Isika;④There is a close relationships between L.caerulea var.edulis and other species of Subsect.so it did not support the L.caerulea var.edulis as a new genus.
