Abstract

This study was conducted to construct the keys for identification based on morghological characters and distributions of genus Spiraea in Korea. The morphological characters analyzed in this study were leaf, inflorescence, floral structure, twig and fruit in 11species 5varieties of genus Spiraea.The results obtained in this study were as follows; 1. Most of species are distributed in central and north region of Korea. Especially, S. prunifolia var. simplicifolia is distributed throughout the Korean penninsula, S. media only in Mt. Baekdu. 2. In leaf characters, S. salicifolia has the largest value of length/width ratio and S. blumei has the regional variation. 3. The most important key for classifying species of genus Spiraea is inflorescence. S. salicifolia has the panicle inflorescence with pale pink color. The identification by pisitil length/flower size ratio also was effective. The pistil lengths were two or three times of the flower lengths in S. miyabei and S. fritschiana. 4. According to this study, Genus Spiraea was divided into three sections of Spiraea, Calospira, Chamaedryon.
