摘　　要：对福建省30种常见榕属植物的22个性状进行形态聚类分析,结果表明:榕属植物各种之间的平均欧氏距离是5.336 8,欧氏距离最近的是日本匍茎榕和珍珠莲,为1.715 5;硬叶榕和大果榕的欧氏距离最远,为9.770 7.从形态标记聚类图可看出,在纵切线位置(欧氏距离为7.575 1)可将福建省30种常见榕属植物分为6个类群,第1类包括6种榕属植物;第2类包括16种榕属植物;第3类、第5类有3种榕属植物;第4类、第6类只有1种榕属植物.研究结果为福建省榕属植物的分类提供可借鉴的资料.The 22 morphological characteristics of 30 species of common Ficus plants in Fujian Province were analyzed by clustering in this study. Results showed that： the average Euclid distance among different Ficus species is 5. 336 8. Euclid distance between Ficus sarmentosa var. impressa and Ficus sarmentosa var. lacrymans is 1. 715 5, which is the closest one, the farthest Euclid dis- tance is between Ficus callosa and Ficus auriculata, which is 9.770 7. At the Euclid distance of 7. 575 1, 30 Ficus species in Fujian Province were clustered into 6 groups： Group Ⅰ include 6 Fi- cus species. Group Ⅱ include 16 species. Both of Group Ⅲ and Group Ⅴ include 3 species, while there is only 1 species in Group Ⅳ and Group Ⅵ. The results can provide useful information for the classification of Ficus plants in Fujian Province.
