The wild tea in Hainan Island was regarded Camellia sinensis var. assamica (CSA) or C. sinensis var. pubilimba (CSB). The concentrated distribution area of the tea is Shuimanxiang, Wuzhishan. In order to further clarify the classification status of the tea, the wild tea plants of eight communities were studied. The morphological characteristics of the tea were closer to CSA than CSB. But there were also obvious differences, since the leaves of the tea was larger than that of CSA and CSB, the side veins of the tea was slightly more than that of CSA and CSB, and the petals of the tea, CSB and CSA was 5, 5-6 and 6-7, correspondingly. The sequence of the psbA-trnH chloroplast coding gene showed that the 30 samples of the eight communities of the tea was an independent group, which is parallel to CSA and CSB. So, the wild tea could also be identified as another variety of C. sinensis. It was named as Camellia sinensis (Linnaeus) Kuntze var. shuiman F. Su and X. B. Yang, short for Shuiman Tea.
