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. | The name ''Camellia'' is taken from the Latinized name of Rev.

The seeds of ''Camellia sinensis'' and ''Camellia oleifera'' can be pressed to yield [[tea oil]], a sweetish seasoning and cooking oil that should not be confused with tea tree oil, an essential oil that is used for medical and cosmetic purposes, and originates from the leaves of a different plant. | The seeds of ''Camellia sinensis'' and ''Camellia oleifera'' can be pressed to yield [[tea oil]], a sweetish seasoning and cooking oil that should not be confused with tea tree oil, an essential oil that is used for medical and cosmetic purposes, and originates from the leaves of a different plant. | ||
The leaves are 4–15cm long and 2–5cm broad. Fresh leaves contain about 4% [[caffeine]]. The young, light green leaves are preferably harvested for tea production; they have short white hairs on the underside. Older leaves are deeper green. Different leaf ages produce differing tea qualities, since their chemical compositions are different. Usually, the tip (bud) and the first two to three leaves are harvested for processing. This hand picking is repeated every one to two weeks. | The leaves are 4–15cm long and 2–5cm broad. Fresh leaves contain about 4% [[caffeine]].

[[Nilgiri]] tea comes from an even higher part of India than Darjeeling. This southern Indian region has elevations between 1,000 and 2,500 metres. The flavors of Nilgiri teas are subtle and rather gentle. They are frequently blended with other, more robust teas. | [[Nilgiri]] tea comes from an even higher part of India than Darjeeling.
