Morus \Mo"rus\, n. [L., mulberry tree. See Mulberry.]

(Bot.) A genus of trees, some species of which produce edible fruit; the mulberry. See Mulberry.

Note:

Morus alba is the white mulberry, a native of India or China, the leaves of which are extensively used for feeding silkworms, for which it furnishes the chief food.

Morus multicaulis, the many-stemmed or Chinese mulberry, is only a form of white mulberry, preferred on account of its more abundant leaves.

Morus nigra, the black mulberry, produces a dark-colored fruit, of an agreeable flavor.
