Compound corymb: When the main axis branches and the flowers are arranged on the branches in a corymbose manner, the inflorescence is a compound corymb as seen in Pyrus torminalis . [6][7] Cymes are further divided according to this scheme: A cyme can also be so compressed that it looks like an umbel. The most common kind of definite compound inflorescence is the panicle (of Webeling, or 'panicle-like cyme'). The most common kind of definite compound inflorescence is the panicle (of Webeling, or 'panicle-like cyme'). of umbra shade. In many cases the last true flower formed by the terminal bud (subterminal flower) straightens up, appearing to be a terminal flower. Compound (triple) umbel. [12][13][14], The shift from the vegetative to reproductive phase of a flower involves the development of an inflorescence meristem that generates floral meristems. Strictly speaking this kind of inflorescence could be called umbelliform cyme, although it is normally called simply 'umbel'. e. Compound spadix The capitulum is composed of many small capitula,surrounded by involucre of bracts, e.g., Echinops echinatus of Asteraceae. This is a compound inflorescence with umbel-like branches. A kind of compound inflorescence is the double inflorescence, in which the basic structure is repeated in the place of single florets. An anthela is a cymose corymb with the lateral flowers higher than the central ones. Indeterminate inflorescence with an acropetal maturation and lateral flower buds. Leafy-bracted inflorescence of Rhinanthus angustifolius. Raceme 2. Capitulum. Guertin, P., Barnett, L., Denny, E.G., Schaffer, S.N. In racemose type, the main axis is unlimited in growth. Branched inflorescence with pedicelled flowers. Other articles where Compound umbel is discussed: angiosperm: Inflorescences: In a compound umbel (see photograph), all the umbel inflorescences arise from a common point and appear to be at about the same level (e.g., wild carrot). Determinate simple inflorescences are generally called cymose. Inflorescence terminal or axillary, sometimes leaf-opposed, usually compound, or sometimes a simple umbel or head or reduced to 1 or a few flowers; umbels usually with bracts (involucre) and umbellules with bracteoles (involucel) at their bases. Often a vestige of the terminal bud may be noticed higher on the stem. An inflorescence is a flowering stem. The most common kind of definite compound inflorescence is the panicle (of Webeling, or 'panicle-like cyme'). Maths.

Bracts may be present. Racemose Inflorescence: In this type of inflorescence, the main axis does not end in a flower, but it grows continuously and develops flowers on its lateral sides in acropetal succession (i.e the lower or outer flowers are older than the upper or inner ones). They are generally arranged in a fixed pattern we call inflorescence. Many verticillasters with reduced bracts can form a spicate (spike-like) inflorescence that is commonly called a spike. Any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium. The Inflorescence. Catkin or Ament: A spike-like inflorescence of unisexual, apetalous flowers, often pendent and falling as a unit. This type of inflorescence is typical of members of the Celery Family (Apiaceae). According to the presence or absence of bracts and their characteristics we can distinguish: 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. italica L.)", "Genetic control of branching pattern and floral identity during Petunia inflorescence development", "Floral Initiation and Inflorescence Architecture: A Comparative View", R J Ferry. Inflorescences usually have modified foliage different from the vegetative part of the plant. The fruiting stage of an inflorescence is known as an infructescence. Simple raceme; Compound raceme; Simple corymb; Compound corymb; Simple Umbel; Compound Umbel; Cymose: Here the inflorescence has a flower at the top of the peduncle. Panicle. Biology. Thumbnails Previous Next. [10] Both types of genes help shape flower development in accordance with the ABC model of flower development. Compound umbel-instead of individual flowers radiating out from a single point, there are instead inflorescence branches.At the ends of each branch are secondary umbels. A panicle is a definite inflorescence that is increasingly more strongly and irregularly branched from the top to the bottom and where each branching has a terminal flower. The involucre of bracts (whorl) is present. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion. Umbels can be simple or compound. The secondary cymes can be of any of the different types of dichasia and monochasia. The family Poaceae has a peculiar inflorescence of small spikes (spikelets) organised in panicles or spikes that are usually simply and improperly referred to as spike and panicle. That is older flowers are present at the bottom while new ones are at the tip.

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 called 'raceme'. The various forms of racemose inflorescence may be described under three heads. See {Umbrella}.] In a compound umbel (see photograph), all the umbel… A flower that is not part of an inflorescence is called a solitary flower and its stalk is also referred to as a peduncle. Considering the broadest meaning of the term, any leaf associated with an inflorescence is called a bract. In racemose type, the main axis is unlimited in growth. Umbel: Flat-topped inflorescence with all the pedicels arising from a common point. Examples – Carrot (Daucas carota), Coriander (Coriandrum sativum), Fennel (Foeniculum vulgare), etc. Umbels can be simple or compound.
