Characteristics of Liverwort and Hornwort Flora of The Korean Peninsula.

Korea is a peninsular on the far east coast of continental Asia. Floristically, it belongs to eastern asiatic floristic region and it has close floristic relationships with Manchuria and adjacent Japan. Korea shows a remarkable variation in climatic conditions as to temperature and precipitation. In addition, the complex mountain system that covers nearly 70% of the total area and ca. 3,400 islands along the west and south coast create very diverse habitats throughout the region. The flora, therefore, shows a great deal of diversity, ranging from warm temperate in the southern part to cold temperate and alpine in the northern and high mountain regions. Based on a study of 12,000 specimens collected by the authors and a review of the relevant literature, the liverwort flora of the Korean Peninsula includes 328 taxa (313 species, five subspecies, and ten varieties) in 101 genera and 48 families, while the hornworts include eight taxa in five genera and three families. These include 61 taxa of liverworts and four of hornworts reported as new to the Korean Peninsula and a description of one new species (Tritomaria koreana Bakalin, S.S. Choi & B.-Y. Sun). Four new combinations are also proposed. While compiling the hepatic flora, 16 species previously reported as native to Korea were excluded from the Korean liverwort flora. In the analysis of area types (longitudinal type), 168 taxa (51.2%) occurred in eastern Asia, 93 (28.3%) were circumpolar, 19 (5.8%) were found in Asia, 13 (3.9%) were amphioceanic, and 13 (3.9%) occurred in multiple areas. Most of the area types belonged to the eastern Asian flora. In an analysis of floristic elements based on latitude, 66 taxa (20.1%) were temperate, 66 (20.1%) were subtropical, 48 (14.6%) were temperate-subtropical, 30 (9.1%) were boreal-temperature, 30 (9.1%) were boreal, 48 (14.6%) were arctic-boreal, 26 (7.9%) were Arctic, and 14 (4.2%) were cosmopolitan species. Temperate and subtropical floristic elements occurred in similar proportions, while there were many more boreal and arctic elements.
