Flower
Definition:
(n.) 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.
(n.) 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.

(n.) Grain pulverized; meal; flour.
(n.) A substance in the form of a powder, especially when condensed from sublimation; as, the flowers of sulphur.
(n.) A figure of speech; an ornament of style.
(n.) Ornamental type used chiefly for borders around pages, cards, etc.
