This study was carried out to survey the distribution of Korean native lilies and environmental conditions of their native habitats.
The results obtained were as follows:
1. The distribution of 9 species of Korean native lilies were identified by the survey of 40 districts of Korean peninsula and islands. Identified species included Lilium lancifolium, L. leichtlinii var. maximowiczii, L. amabile, L. cernum, L. concolor var. partheneion, L. callosum, L. distichum, L. tsingtauense, L. hansonii, etc.
2. L. lancifolium, L. amabile and L. tsingtauense were distributed most of all over the country, but occurrance frequency of L. amabile and L. tsingtauense was lower than that of L. lancifolium. L. amabile was seldom discovered in seashore sites of the west or south coast, and L. tsingtauense was never found in Kangweon Province.
3. The distribution of L. concolor, L. callosum, L. cernum, L. leichtlinii var. maximowiczii were limited to only a few districts. L. distichum could be found in the area neighboring mountain summit with altitude of above 1,000m. L. hansonii was discovered only in Ulreungdo, especially in the valleys and sloped mountainous sites adjacent to Mt. Seonginbong.
4. Most of native inhabitat places of lilies were located at well drained sloped sites. L. concolor var. partheneion, L. leichtlinii var. maximowiczii, L. amabile, and L. lancifolium were distributed largely at the sunny side with infertile silt loam soil texture, while L. tsingtauense, L. distichum, L. hansonii, and L. cernum were found in shaded areas of mountains with high organic matter content.
5. Deciduous shrubs, trees and herbaceous plants such as Rhododendron, Lespedeza and Miscanthus species were dominant among the flora of native inhabitats of lilies. From this reason, lily plants were able to accept the full sunlight in the early spring season.
