CYNOGLOSSUM, HOUND'S TONGUE: A genus of the monogynia order, belonging to the pentandria class of plants; and in the natural method ranking under the 41st order, Asperifolia. The corolla is funnel-shaped, with its throat closed up by little arches formed in it; the feeds depressed, and affixed to the style or receptacle only on their inner side. There are eight species, none of them remarkable for their beauty. The root of one of them, viz. the officinale, or common greater hound's tongue, was formerly used in medicine, and supposed to possess narcotic virtues; but it is discarded from the present practice. The smell of the whole plant is very disagreeable. Goats eat it: sheep, horses, and swine refuse it.
