The prepared leaf, chiefly of either T. Bohea, or T. viridis, indiffer- 

 ently, Black Teas, and Green Teas. 



Vernacular. Char, By. 



Habitat. China, Japan. The variety T. Bohea is cultivated about 

 Canton, and T. viridis about Hwuychow. A variety, T. assamica ? 

 is also cultivated in Assam. 



Remarks. Tea is first mentioned (except by the Chinese) in an 

 Arabian itinerary of the ninth century. All the cultivated Teas are 

 now considered to be mere varieties of T. chinensis. Neither of these 

 yield exclusively either Black or Green Teas, but both T. Bohea 

 and T. viridis yield both Black and Green according to the treat- 

 ment of their leaves. T. viridis cultivated about Hwuychow yields the 

 best Black 'and Green Teas, and T. Bohea about Canton, tht inferior 

 kinds. The principal kinds of Black Tea are Bohea, Pekoe, Souchong, 

 Campoi, Congou, and Caper; and of Green, Imperial, Twankay, 

 Hyson-skin, and Gunpowder. True Imperial "Flos-these" is rarely 

 seen in Europe, an inferior kind scented with the blossoms of Olea fragrant 

 being substituted. The Chinese perfume their teas with various odori- 

 ferous plants and name them accordingly, as the rose, plum, Jasminum 

 Sambac, Aglaia odorata, orange, Gardenia florida, Cloranthus inconspi- 

 cuus t Murraya exotica, Vitex spicata, Camellia Sasanqua, Camellia 

 odorifera, Illicium anisatum, Magnolia Tulan ; and with turmeric, orris- 

 root, and oil of arnotto. Some of the inferior descriptions of teas are 

 adulterated with Prussian-blue, gypsum, &c. to improve their appearance. 

 Lie-tea consists of the sweepings of the tea warehouses cemented together 

 with rice-water and rolled into grains. Brick-tea is essentially Lie-tea 

 damped with bullock's blood and pressed into a mould. An infusion of it 

 is beef tea and tea at once. The Chinese also prepare lozenges with the 

 extract of tea leaf which are exceeding refreshing. The narcotic effects 

 of tea on man, seem to increase towards the equator. There are twelve 

 varieties of Canton teas in the museum.
