Trees or shrubs with alternate, simple, feather-veined, exstipulate leaves. Flowers regular, polyandrous, hypogynous, cyanic, with sepals and petals imbricated, the former often unequal in size. Stamens more or less coherent at base into one, three or five sets. Anthers 2-celled. Seeds few, with little or no albumen, cotyledons large.

Genera 33, species 130. Beautiful flowering plants, 60 or 70 of them natives of S. America, 4 of N. America, the remainder of China and E. Indies. Their properties are stimulating and slightly narcotic. The tea, so extensively used as a beverage in the civilized world is the leaf of '2 or 8 species of Thea. In contains a peculiar extractive matter called theine, and a stimulating, essential oil, which becomes narcotic in some hot climates. Thea Bohea and T. viridis are the two species which yield all the varieties of Chinese teas, according to the various methods of preparing the leaves.

Trees with large, white, axillary, pedunculate flowers.
