     1. (Bot.)
        (a) A ripened ovule, consisting of an embryo with one or
            more integuments, or coverings; as, an apple seed; a
            currant seed. By germination it produces a new plant.
        (b) Any small seedlike fruit, though it may consist of a
            pericarp, or even a calyx, as well as the seed proper;
            as, parsnip seed; thistle seed.
            [1913 Webster]
  
                  And God said, Let the earth bring forth grass,
                  the herb yielding seed, and the fruit tree
                  yielding fruit after his kind, whose seed is in
                  itself.                           --Gen. i. 11.
            [1913 Webster]
  
     Note: The seed proper has an outer and an inner coat, and
           within these the kernel or nucleus. The kernel is

           albumen, which is the material for the nourishment of
           the developing embryo. The scar on a seed, left where
           the stem parted from it, is called the hilum, and the
           closed orifice of the ovule, the micropyle.

     5. Progeny; offspring; children; descendants; as, the seed of
        Abraham; the seed of David.
        [1913 Webster]
  
     Note: In this sense the word is applied to one person, or to
           any number collectively, and admits of the plural form,
           though rarely used in the plural.
           [1913 Webster]
