FLOW'ER, n. [L. flos, floris, a flower; floreo, to blossom. See Flourish.]

1. In botany, that part of a plant which contains the organs of fructification, with their coverings. A flower, when complete, consists of a calyx, corol, stamen, and pistil; but the essential parts are the anther and pistil, which are sufficient to constitute a flower, either together in hermaphrodite flowers, or separate in male and female flowers. Martyn. Milne.
2. In vulgar acceptation, a blossom or flower is the flower-bud of a plant, when the petals are expanded; open petals being considered as the principal thing in constituting a flower. But in botany, the petals are now considered as a finer sort of covering, and not at all necessary to constitute a flower. Milne.

   * 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.
