REFERENCE TO THE PLATE.

This plant seems to have been hitherto but imperfectly known, having been figured among Dr. Roxburgh’s Coromandel Plants, vol. i. p. 20, under the title of Grislea tomentosa. It has recently received another new generic title; but upon examination we find it to be the Lythrum of Linnæus; in which opinion the author is sanctioned by the concurrence of some of the ablest botanists of the present day. This handsome shrub is described in the 4th vol. of the Asiatic Researches, under the native title of D.hawry, and is said to grow wild on the hills and banks of rivulets in the northern part of Hindostan, where it is as much esteemed for its utility as its beautiful red flowers, which are gathered both for the use of dyers and apothecaries; the latter giving an infusion of them as a cooling medicine. When used in dyeing, they lose their colour, and only yield a slight brownish tincture to the water; so that the benefit derived from them when used with [A]Aal seems to depend solely on their action as an astringent, and which appears to be confirmed by the substituting of [B]Purwas, a strong astringent, as an equivalent for the flowers of the D.hawry. It is at present treated as a hot-house plant, but would in all probability succeed very well in the careful treatment of the green-house. The figure was taken from a fine plant in the nursery of Messrs. Colville.
