(n.) A class of objects divided into several subordinate species; a class more extensive than a species; a precisely defined and exactly divided class; one of the five predicable conceptions, or sorts of terms.
(n.) An assemblage of species, having so many fundamental points of structure in common, that in the judgment of competent scientists, they may receive a common substantive name. A genus is not necessarily the lowest definable group of species, for it may often be divided into several subgenera. In proportion as its definition is exact, it is natural genus; if its definition can not be made clear, it is more or less an artificial genus.

Ginseng
Definition:
(n.) A plant of the genus Aralia, the root of which is highly valued as a medicine among the Chinese. The Chinese plant (Aralia Schinseng) has become so rare that the American (A. quinquefolia) has largely taken its place, and its root is now an article of export from America to China. The root, when dry, is of a yellowish white color, with a sweetness in the taste somewhat resembling that of licorice, combined with a slight aromatic bitterness.
