Seed \Seed\, n.; pl. {Seed} or {Seeds}. [OE. seed, sed, AS. s?d,
   fr. s[=a]wan to sow; akin to D. zaad seed, G. saat, Icel.
   s[=a]?, s??i, Goth. manas?ps seed of men. world. See {Sow} to
   scatter seed, and cf. {Colza}.]
   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.

                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.

   Note: The seed proper has an outer and an inner coat, and
         within these the kernel or nucleus. The kernel is
         either the embryo alone, or the embryo inclosed in the
         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.

   2. (Physiol.) The generative fluid of the male; semen; sperm;
      -- not used in the plural.

   3. That from which anything springs; first principle;
      original; source; as, the seeds of virtue or vice.

   4. The principle of production.

            Praise of great acts he scatters as a seed, Which
            may the like in coming ages breed.    --Waller.

   5. Progeny; offspring; children; descendants; as, the seed of
      Abraham; the seed of David.

   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.

   6. Race; generation; birth.

            Of mortal seed they were not held.    --Waller.

      of water down the bore hole. It consists of a bag
