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-coloured fruit, of an agreeable flavor.
Origin: L, mulberry tree. See Mulberry.
