   Note: If we examine a common flower, such for instance as a
         geranium, we shall find that it consists of: First, an
         outer envelope or calyx, sometimes tubular, sometimes
         consisting of separate leaves called sepals; secondly,
         an inner envelope or corolla, which is generally more
         or less colored, and which, like the calyx, is
         sometimes tubular, sometimes composed of separate
         leaves called petals; thirdly, one or more stamens,
         consisting of a stalk or filament and a head or anther,
         in which the pollen is produced; and fourthly, a
         pistil, which is situated in the center of the flower,
         and consists generally of three principal parts; one or
         more compartments at the base, each containing one or
         more seeds; the stalk or style; and the stigma, which
         in many familiar instances forms a small head, at the
         top of the style or ovary, and to which the pollen must
         find its way in order to fertilize the flower. --Sir J.
         Lubbock.

   3. The fairest, freshest, and choicest part of anything; as,

      youth.
