Unlike vegetative parts, the reproductive parts of tea plant are more discrete and show relatively less variation. They therefore provide more reliable diagnostic criteria. The purpose of the study is to got informations of the flower structure and variations on the wild tea germplasm collected from Jeonnam province in Korea. 331 wild tea samples were used in this study, namely, 144 accessions from Wolchul mountain, 178 accessions from Moodeung mountain, and 9 accessions from Boseong district, and all were collected within the Jeonnam province. Another 9 improved cultivars from Japan were also used for comparison. The collected wild tea plants and the Japanese tea cultivars have mainly medium flowers except for the 16 accessions (9%) from Moodeung mountain have large flowers. The length of stigma and stamen differed among the Korean tea accessions, whereas the Japanese cultivars were similar. Many Korean wild tea plants (over 65%) showed high position of stigma with 98 accessions (55.1%) from the Moodeung mountain group and 82 accessions (56.9%) from the Wolchul mountain, but the Japanese tea cultivars showed low position (below 65%). In the density of ovary pubescence, the Japanese tea cultivars showed medium character due to artificial crossing between Camellia assamica and Camellia sinenses. It was considered that the Korean wild tea plants have varietal distribution due to many natural crossing with unknown pathways.
