The figures are diagrams, representing sections through the leaf, in the way they were represented by Linnaeus. 196. Section VII r. FLOWERS. 196. Flowers are for the production of seed (16). Stems and branches, which for a time put forth leaves for vegetation, may at length put forth flowers for reproduction. § 1. POSITION AND ARRANGEMENT OF FLOWERS, OR INFLOR- ESCENCE. 197. Flower-buds appear just where leaf-buds appear; that is, they are either terminal or axillary (47-49). Morphologically, flowers answer to shoots or branches, and their parts to leaves. 198. In the same species the flowers are usually from axillary buds only, or from terminal buds only; but in some they are both axillary and terminal. 199. Inflorescence, which is the name used by Linnseus to signify mode of flower-arrangement, is accordingly of three classes: namely, Indeterminate^ when the flowers are in the axils of leaves, that is, are from axillary buds; Determinate, when they are from terminal buds, and so terminate a stem or branch; and Mixed, when these two are combined. 200. Indeterminate Inflorescence (likewise, and for the same reason, called indefinite inflorescence) is so named because, as the flowers all come from axillary buds, the
