inflorescence

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. A characteristic arrangement of flowers on a stem.
2. n. A flower cluster.
3. n. A flowering.

Century Dictionary and Cyclopedia

1. n. A beginning to blossom; a flowering; the unfolding of blossoms.
2. n. In botany, the arrangement of flowers on the axis and in relation to each other. This term, meaning literally time of flower-bearing, was first proposed by Linnæus, and should be replaced by the more correct term anthotaxis, which is formed on the analogy of phyllotaxis. Inflorescence is really the subject of ramification or branching, but is also interested in part in foliation and phyllotaxy. Not withstanding the seemingly many diverse kinds of inflorescence, they are all reducible to two fundamental types, the definite or cymose and the indefinite or botryose. The figures above illustrate some of the most important modifications of the two types.
3. n. See the adjectives.
4. n. In botany:
5. n. The portion of a plant devoted to reproduction, including the flowers, peduncles, rachides, general axes, flower-stalks, scapes, etc.
