Raceme: an unbranched inflorescence with several flowers.Aloe hereroensis, showing inflorescence with branched peduncleCompound raceme or Panicle: When the axis of a raceme branches and the flowers are borne not directly on the axis but on its branches then the inflorescence is called a panicle. In this type of inflorescence, the main axis is unlimited in growth, branched or unbranched.cyme: a flat-topped or convex flower cluster in which the uppermost flowers open first. Besides, there is also a special type of inflorescence which fits into none of these groups. It may be terminal or axillary in position. Inflorescence is the reproductive shoot, bearing a number of flowers.

A cyme (rhymes with lime) is an inflorescence that is broad and often flat-topped. An inflorescence in which each terminal growing point produces flowers. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes.Another kind of definite simple inflorescence is the raceme-like cyme or botryoid that is as a raceme with a terminal flower and is usually improperly.cyme. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. B.An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches.

A bract is usually located at the node where the main stem of the inflorescence forms, joined to the rachis of the plant, but other bracts can exist within the inflorescence itself. Considering the broadest meaning of the term, any leaf associated with an inflorescence is called a bract. BractsInflorescences usually have modified foliage different from the vegetative part of the plant. These structural types are largely based on natural selection. These terms are general representations as plants in nature can have a combination of types. 3.2 Meristems and inflorescence architectureInflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowers and how different clusters of flowers are grouped within it.

Bracteate inflorescences: The bracts in the inflorescence are very specialised, sometimes reduced to small scales, divided or dissected. Ebracteate inflorescences: No bracts in the inflorescence. According to the presence or absence of bracts and their characteristics we can distinguish:

If the inflorescence has a second unit of bracts further up the stem, they might be called an involucel.Leafy inflorescence of Aristolochia clematitis.Plant organs can grow according to two different schemes, namely monopodial or racemose and sympodial or cymose. Leafy-bracted inflorescences: Intermediate between bracteate and leafy inflorescence.If many bracts are present and they are strictly connected to the stem, like in the family Asteraceae, the bracts might collectively be called an involucre. This use is not technically correct, as, despite their 'normal' appearance, these leaves are considered, in fact, bracts, so that 'leafy inflorescence' is preferable.

The terminal bud forms a terminal flower and then dies out. Determinate inflorescence: Sympodial (cymose) growth. A terminal flower is never formed. The terminal bud keeps growing and forming lateral flowers. Indeterminate inflorescence: Monopodial (racemose) growth.

Often a vestige of the terminal bud may be noticed higher on the stem.Similarly arrangement of leaf in bud is called Ptyxis.When a single or a cluster of flower(s) is located at the axil of a bract, the location of the bract in relation to the stem holding the flower(s) is indicated by the use of different terms and may be a useful diagnostic indicator. In many cases the last true flower formed by the terminal bud ( subterminal flower) straightens up, appearing to be a terminal flower. In an indeterminate inflorescence there is no true terminal flower and the stem usually has a rudimentary end. Based on phylogenetic analyses, this mechanism arose independently multiple times in different species. It is suggested that indeterminate flowers have a common mechanism that prevents terminal flower growth. The indeterminate patterning of flowers is derived from determinate flowers.

The main kind of racemose inflorescence is the raceme ( / Л€ r Г¦ s iЛђ m/, from classical Latin racemus, cluster of grapes). When the formation of the bud is shifted up the stem distinctly above the subtending leaf, it is described as concaulescent.Inflorescence of sessile disc florets forming the capitulum Indeterminate or racemoseIndeterminate simple inflorescences are generally called racemose / Л€ r Г¦ s ЙЄ m oКЉ s/. Recaulescences is the fusion of the subtending leaf with the stem holding the bud or the bud itself, thus the leaf or bract is adnate to the stem of flower. When the bract is attached to the stem holding the flower (the pedicel or peduncle), it is said to be recaulescent sometimes these bracts or bracteoles are highly modified and appear to be appendages of the flower calyx. Other plants have the bracts subtend the pedicel or peduncle of single flowers. When the parts fused together are the same, they are connately joined.)

It is characteristic of Umbelliferae. An umbel is a type of raceme with a short axis and multiple floral pedicels of equal length that appear to arise from a common point. A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones. A spike is a type of raceme with flowers that do not have a pedicel. A raceme is an unbranched, indeterminate inflorescence with pedicellate (having short floral stalks) flowers along the axis. Some passage forms between the obvious ones are commonly admitted.

The main kind of cymose inflorescence is the cyme (pronounced 'saim', from the Latin cyma in the sense 'cabbage sprout', from Greek kuma 'anything swollen'). Cymose or other complex inflorescences that are superficially similar are also generally called thus.Determinate simple inflorescences are generally called cymose. A catkin or ament is a scaly, generally drooping spike or raceme. It is characteristic of Dipsacaceae. A flower head or capitulum is a very contracted raceme in which the single sessile flowers share are borne on an enlarged stem. It is characteristic of the family Araceae.

Secondary axis still dichasial: dichasium (characteristic of Caryophyllaceae) The successive pedicels follow a zig-zag path on the same plane: rhipidium (many Iridaceae) The successive pedicels are arranged in a sort of spiral: cincinnus (characteristic of the Boraginaceae and Commelinaceae) Secondary buds develop alternately on the stemВ : scorpioid cyme The successive pedicels are aligned on the same plane: drepanium Secondary buds always develop on the same side of the stem: helicoid cyme or bostryx
