Texa of Lycoris in Korea were classified as five species with two varieties and revised taxonomically. Among the examined taxa, five Korean endemic plants were clarified: Lycoris flavescens M. Kim et S. Lee, L. uydoensis M. Kim, L. chejuensis Tae et S. Ko, L. chinensis var. sinuolata Tae et S. Ko, and L. sanguinea var. koreana (Nakai) T. Koyama. It was found that L. flavescens, L. uydoensis, and L. chejuensis were the natural hybrids between taxa of M+T karyotype and A karyotype. A specimen collected on Aug. 20, 1987 by M. Kim was designated as a holotype of Lycoris flavescens M. Kim et S. Lee. Lycoris flavescens var. uydoensis was ranked up to L. uydoensis. A key to all species including descriptions of each taxon was provided.

Phylogenetic relationships were examined for 17 taxa of Lycoris by RAPD analysis. The length of the amplified DNA fragments ranged from 300 bp to 1,700 bp. 57 scorable RAPD markers were observed from PCR reactions with five random oligoprimers. The analysis by UPGMA sepatated the examined taxa of Lycoris into were clusters. First group was comprised of ten taxa of L. chinensis var. sinuolata, L. sanguinea var. koreana, L. uydoensis, L. flavescens, L. radiata var. pumila, L. radiata, L. squamigera, L. chejuensis, L. aurea and L. guangxiensis, second group of L. haywardii, L. sprengeri, L. rosea, L. straminea and L. houdyshii, third group of outgroup of Narcissus tazetta var. chinensis and Crinum asiaticum var. japonicum. From the viewpoint of cytological characters such as polyploidy and karyotype, the RAPD analysis was very useful to show the relationship among the intraspecific taxa of Lycoris.
