The classification of finite inflorescence
1, a single manifold cyme (monochasium) Mr. spindle top of a flower, and then spent the following in the top side of the spindle to form a lateral branch, the same flower in the branch side, there may be collateral branch of the Health and flowers as before, so the whole inflorescence is a co-axial branches. If the branches, each branching into right and left give birth interval, while the branches and flowers are not the same plane, said this cyme Heliconia-like cyme (scorpioid cyme), such as Potentilla, gladiolus's inflorescence. If the time separation of the lateral branches are growing towards one direction, called spiral-like cyme (helicoid cyme), such as forget-grass inflorescence. 2, two differences cyme (dichasium) Rachis top flowers open first, in the bottom so long to give birth to two branches, each branch and treat ways to continue flowering and branching, that two differences cyme, also known as discrimination umbrella inflorescence. Under the top flower on each side of the spindle toward the meristematic one, the top flower branches, each branch and then branch on both sides, so repeatedly, such as volume ear, chickweed, Euonymus japonicus, etc. 3, multi-manifold cyme (pleiochasium) Spindle top growth of a flower, the top flower on the right under the separation of the spindle a few more branches, each branch has self-contained small cyme, such as Euphorbia, Motherwort, etc. inflorescence. Euphorbia flower stems short intensive, said dense umbrella inflorescence; Motherwort flowers sessile, several layers of Health, said the round umbrella inflorescence. 4, round umbrella inflorescence (verticillaster) Cyme was born on the leaf axils of the leaves, round shaped sort, that round umbrella inflorescence, such as Motherwort, mint, etc.
