This study was conducted to clarify not only the phytogeographical distribution but also species characteristics of Korean-native Anacardiaceae. 6 species of I genus were ascertained from herbarium specimens and field survey of natural population. Rhus verniciflua have been mainly cultivated in Wonju region, Kangwon-do and Hamyang region, Kyeongsangnam-do, could be cultivated in all parts of Korea, especially more in cold area. R. trichocarpa was distributed in all parts except for some far-islands of South in Korea. Petiole was especially reddish. Fruits are matured in June-July, and have stiff trichomes. R. sylvestris was widely distributed in the subtropical-temperate and temperate zone, and mainly distributed in the seashore and islands under 36$^{\circ}$ in Korea. Leaflets and petiole was reddish, and fruits were glabrous. R succedanea was only distributed in Jeju-do and several islands which is subtropical zone in Korea. Leaflets were lanceolate to oblong, characterized by little trichomes. R.chinensis is a ubiquitous tree which is widely distributed in the temperate zone, in Korea, and ranged perpendicularly to 800-900m. Inflorescense was characterized by apical site. Fruit was covered with dense short hairs and sometimes milky latex. R. ambigua was only distributed in subtropical zone, native in Kwang-do and Sangbaek-do, Yeochon-gun, Chunlanam-do in Korea. Especially, this species was a vine, trifoliolate and most poisonous. Leaflets were coriaceous, glabrous, and revolute type.
