In its characters this plant, received from Assam, agrees in part with those assigned by Dr. Lettsom and Sir W. Hooker to the _Thea viridis_, but differs in its branches being stiff and erect. The flowers small, or rather much about the same size as the species about to be described, and not confined to the upper axils of the plant, and solitary, as stated by them.[10] By the Chinese manufacturers it is considered an inferior plant for making tea, it is not therefore grown to any extent. The second species is characterised by its leaves being much smaller, and not so broadly lanceolate; slightly waved, of a dark-green color, thick and coriaceous, sinature or edge irregular, length from one to three inches and a half. In its growth it is much smaller than the former, and throws out numerous spreading branches, and seldom presents its marked leading stem. This species, therefore, in the above characters, agrees much with those that have been assigned to _Thea Bohea_ by authors. The characters have been mixed up in an extraordinary manner. Thus it has been stated, that the _Thea viridis_ has large, strong growing, and spreading branches, and that _Thea Bohea_ is a smaller plant, with branches stiff and straight, and stem erect. No doubt the _Thea viridis_ is a much larger and stronger growing plant than the _Thea Bohea_, or rather the plant now existing in the different plantations is so; but in the former the branches are stiff and erect, and in the latter inclined and branches. The marked distinguishing characters between the two species are the coriaceous dark-green leaves in the _Thea Bohea_, and the large pale-green monhanæous leaves of the _Thea viridis_. The manner, too, of growth is very striking, and on entering the plantation the distinction is at once marked to the most unobservant eye. This species of _Thea Bohea_ forms nearly the whole of the plantations, and was brought from China by Dr. Gordon. In the plantations there is a third plant, which, however, can only be considered a marked variety of _Thea Bohea_. Its leaves are thick, coriaceous, and of dark-green color, but invariably very small, and not exceeding two inches in length, and thinly lanceolate; the serratures, too, on the edge, which are straight, are not so deep. In other characters it is identical. This marked variety was received from Calcutta at the plantation in a separate despatch from the others.
