1. In the popular sense, the bloom or blossom of a plant; the showy portion, usually of a different color, shape, and texture from the foliage. [1913 Webster]
2. (Bot.) That part of a plant destined to produce seed, and hence including one or both of the sexual organs; an organ or combination of the organs of reproduction, whether inclosed by a circle of foliar parts or not. A complete flower consists of two essential parts, the stamens and the pistil, and two floral envelopes, the corolla and callyx. In mosses the flowers consist of a few special leaves surrounding or subtending organs called archegonia. See Blossom, and Corolla. [1913 Webster]
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. [1913 Webster]
3. The fairest, freshest, and choicest part of anything; as, the flower of an army, or of a family; the state or time of freshness and bloom; as, the flower of life, that is, youth. [1913 Webster]
