                  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

           the stem parted from it, is called the hilum, and the
