This [[varietal]] is wild growing and native to southeast Asia. It reaches heights of 20 to 30 feet and is mainly used for [[Pu-Erh]] tea. It resembles the assamica variety but its leaves are smaller in length. It's considered a cross between assamica and sinensis. + − Line 46:

There are two major varieties used for tea, Chinese tea, ''Camellia sinensis'' var. ''sinensis'', and Assam tea, ''Camellia sinensis'' var. ''assamica''.
Beside this two there is also ''Camellia sinensis'' var. ''pubilimba'' and ''Camellia sinensis'' var. ''dehungensis''. They are also known as Mao Cha (毛茶) and used for Pu-Erh tea. It's unclear whether those two varietal are own species or just a spontaneous hybrid of assamica and sinensis. The same applies for the varietal called "java bush", ''Camellia sinensis'' var. ''parvifolia'' or ''Camellia sinensis'' var. ''cambodiensis''.

==Nomenclature and taxonomy==
The name ''Camellia'' is taken from the Latinized name of Rev. Georg Joseph Kamelref, Society of Jesus (1661–1706), a Czech-born Jesuit lay brother, pharmacist, and missionary to the Philippines. Carl Linnaeus chose his name in 1753 for the genus to honor Kamel's contributions to botany (although Kamel did not discover or name this plant, or any ''Camellia'' and Linnaeus did not consider this plant a ''Camellia'' but a ''Thea''. The name ''sinensis'' means ''from China'' in Latin.
