Abstract
Botanically speaking, Camellia sinensis (L.) O. Kuntze is a woody evergreen plant of the genus Camellia in the Theaceae family, native to southern China. It has a genome of 4,000 Mb (Tanaka et al. 2004) with a base number of n = 15. Known varieties are sinensis and assamica. The former grows in the wild, mainly in southern China, and the latter is found over a wide area of southeastern Asia, from southern China to India. There is no known natural growth of C. sinensis in Sri Lanka, a prominent tea producer. Variety sinensis is a low shrub characterized by small rounded leaves and cold hardiness. Conversely, variety assamica is an arboreous plant characterized by large, pointed leaves more serrated than those of variety sinensis and low tolerance to cold. Although many intermediate morphologies exist in southern China, presumably resulting from interbreeding of the two varieties, a comparison of typical variety sinensis and typical variety assamica finds significant morphological differences as if the two varieties are unrelated.
