Nomenclature and taxonomy

. Carl Linnaeus chose his name for the genus to honor Kamel's contributions to botany (alhough 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

Four varieties of Camellia sinensis are recognized. Of these C. sinensis var. sinensis and C. sinensis var. assamica (J. W. Masters) Kitamura are most commonly used for tea, and C. sinensis var. pubilimba Hung T. Chang and C. sinensis var. dehungensis (Hung T. Chang & B. H. Chen) T. L. Ming are sometimes used locally.

. 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.

 on the UK mainland. Many high quality teas are grown at high elevations, up to 1500 meters (5,000 ft), as the plants grow more slowly and acquire a better flavour.

Tea plants will grow into a tree if left undisturbed, but cultivated plants are pruned to waist height for ease of plucking. Two principal varieties are used, the small-leaved Chinese variety plant (C. sinensis sinensis) and the large-leaved Assamese plant (C. sinensis assamica), used mainly for black tea.

Indian teas

There are three main kinds of tea produced in India:

Assam tea
Assam is a black tea named after the region of its production, Assam, in India. Assam tea is manufactured specifically from the plant Camellia sinensis var. assamica . This tea, most of which is grown at or near sea level, is known for its body, briskness, malty flavor, and strong, bright color...

 - Assam tea comes from the northeastern section of the country. This heavily forested region is home to much wildlife, including the rhinoceros
Rhinoceros , also known as rhino, is a group of five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to southern Asia....

. Tea from here is rich and full-bodied. It was in Assam that the first tea estate was established, in 1837.

Darjeeling tea

 - The Darjeeling region is cool and wet, and tucked in the foothills of the Himalayas

. The tea is delicately flavored, and considered to be one of the finest teas in the world. The Darjeeling plantations have 3 distinct harvests, termed 'flushes', and the tea produced from each flush has a unique flavor. First (spring) flush teas are light and aromatic, while the second (summer) flush produces tea with a bit more bite. The third, or autumn flush gives a tea that is lesser in quality.

Nilgiri tea
Nilgiri tea is generally described as being a dark, intensely aromatic, fragrant and flavoured tea grown in the southern portion of the Western Ghats mountains of Southern India...

 - This 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.

Chinese teas

The Chinese plant (sometimes called C. sinensis var. sinensis) is a small-leaved bush with multiple stems that reaches a height of some 3 meters. It is native to southeast China. The first tea plant to be discovered, recorded and used to produce tea three thousand years ago, it yields some of the most popular teas.

C. sinensis var. waldenae was considered a different species, Camellia waldenae by S.Y.Hu, but it was later identified as a variety of C. sinensis. This variety is commonly called Waldenae Camellia. It is seen on Sunset Peak
