-This study was conducted to examine the morphological characteristics and variations of the 6 populations of Pourthiaea. villosa (Thunb.) Decne. var. villosa in Korea. The ANOVA results showed that the populations were significantly different in 18 of the 21 quantitative characteristics that were analyzed. In the results of principal component analysis, 6 principal components (PC) represented 68.28% for the total variations. 'Petiole length' (0.764), 'Leaf shape' (0.834), 'Leaf length' (0.753), 'Crown diameter' (0.663), 'Inflorescence width' (0.492), and 'Leaf base shape' (0.721) showed the highest contribution to PC1, PC2, PC3, PC4, PC5, and PC6, respectively. According to the results of cluster analysis, one cluster comprised only 'Goesan-gun Ssanggok Valley' population. 'Namhae-gun Mijori Evergreen Forest' population was grouped with 'Hamyang-gun Sang Forest' population, which was the nearest subgroup. Further, 'Namhae-gun Geum Mountain' population, 'Jindo-gun Cheomchal Mountain' population, and 'Jeju-si Barimae Parasitic volcano' population were placed in the same cluster.
