Bunch
In Botanical, the bunch, or the racème , is a simple Inflorescence, i.e. a whole of Fleur S laid out according to a certain order on a common axis. It is an indefinite inflorescence, in which the axis ends in a final bud, with potentially indefinite growth, and side floral buds, whose development is proportional to their age, the flowers being carried by simple side Pédoncule S. Flowering starts with the flowers of the base and continues towards the top (order acropète), giving to the bunch the form characteristic of a Pyramide. So it is frequent to find on the same bunch, as on much of inflorescences, all the stages of evolution of the flower, the buttons in formation at the top, the flowers opened out in the medium and the already ripe Fruit S at the base.
The provision of the flowers on the stem follows the rules of the Phyllotaxie, the observation angles being the same ones as those met for the provision of the Feuille S and the secondary branches. This provision is in the case general multilateral, one can meet unilateral bunches: (the Lily of the valley of May), or bilateral: (the gess).
In the language running, the bunch rather evokes a fruit made up of small bay S, and in very first place that of the Vigne, the Raisin. Actually, from a botanical point of view, the inflorescence of the vine is a thyrse, i.e. a bunch of cymes (thus a made up inflorescence). The bunch of grapes deprived of its grains is called the Rafle.
Example of inflorescences in bunch: the glycine, the Robinier.
The bunch can be in composed inflorescences, of which the Panicule, which is a bunch of bunches.
