In annual plants, after a certain number of leaves have been formed, the terminal bud, and very often some of the axillary buds, assume a different character, and the plant now begins to produce flower-buds in the place of leaf-buds: in perennial plants, such as trees, this change is generally confined to the axillary buds. These flower-buds exhibit many variations in the manner of their arrangement on their stalk and its branches, and the term inflorescence is applied to the whole assemblage of flowers in each case. Thus, if the terminal bud produces a branched bunch of flowers, as in the Mignonette, the whole assemblage of flowers, with their stalk down to the uppermost true leaf upon the stem, is called a terminal inflorescence; the little bunch of flowers produced from the axillary bud in the Currant, and in almost all trees, is called an axillary inflorescence. In this inflorescence, whether axillary or terminal, we have a number of different parts to distinguish. In the first place, the main stalk of an inflorescence is called the peduncle (fig. 15, a); and this is either the direct continuation of the stem, as in the Mignonette, or it arises as a branch in the axil of a regular leaf, as in the Pimpernel and the Cucumber, or in the axil of one of those altered leaves which were mentioned in a former section under the name of bract, as in the Currant. In the Lime the peduncle adheres to the bract, so as to appear as if it arose from the middle of it instead of from its axil. The peduncle may be simple, bearing one solitary flower, as in the Snowdrop; or it may be branched, bearing many flowers on stalks of various lengths: these stalks are called pedicels (fig. 15, b). ...
