The inflorescence is the arrangement of flowers in a cluster on the stem of various plants. Each of these arrangements has its specific name. The arrangement helps to facilitate sexual reproduction in various ways. In this article, we will provide detailed information about Inflorescence. Define Inflorescence
Racemose inflorescence Characteristics, Types, Example
The types are: 1. Solitary Flowers 2. Racemose Inflorescence 3. Cymose Inflorescence 4. Mixed Inflorescence 5. Special Inflorescence. Type # 1. Solitary Flowers: Flowers occur singly or are separated from other flowers of the same plant by vegetative regions. Solitary flowers are formed by direct transformation of shoot tips into flowers.
Inflorescence Classification, Types, Significance, Examples
Spike. Florets are sessile, attached directly to a central axis. Raceme. Similar in structure to a spike, but the florets have pedicels. Panicle. A branched raceme.

Capitulum - Inflorescence axis is flattened to form a receptacle wherein ligulate ray florets and tubular disc florets develop in a centripetal manner. Example - Tridax.

An inflorescence consisting of a head of small closely packed stalkless flowers or florets arising at the same level on a flattened axis. The whole is surrounded or subtended by an * involucre of bracts and simulates, in appearance and function, a single large flower. The capitulum is typical of members of the family Compositae.

V. FLOWERS ALL ATTACHED AT THE SAME POINT(umbel and head/capitulum) An inflorescence in which several-many pedicellate (stalked) flowers are attached at the same point on a peducnle is called an UMBEL. The umbel is a fairly common inflorescence type. Simple umbels are produced by many clovers (genus Trifolium in Fabaceae, the legume family).

It is an aggregation or cluster of flowers displayed in a specific pattern for a particular plant species. The stem holding this whole reproductive portion of a plant is called a peduncle. The major axis above the peduncle called rachis bears the flowers or secondary branches.

An indeterminate inflorescence may be a raceme, panicle, spike, catkin, corymb, umbel, spadix, or head. lily of the valley. A raceme of lily of the valley (Convallaria majalis). In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. Each flower is borne on a short stalk.

Head (also called a composite or capitulum) Figure 8.4.3 8.4. 3: A dandelion head inflorescence. Each "petal" is actually composed of five fused petals of a single floret. The tube-like structures emerging upward are the styles, each with two curled stigma lobes. Because this inflorescence has no disc flowers, it is called a ligulate head.

The capitulum is a contracted raceme composed of numerous individual sessile flowers, called florets, all sharing the same receptacle. A set of bracts forms an involucre surrounding the base of the capitulum. These are called "phyllaries", or "involucral bracts". They may simulate the sepals of the pseudanthium.
The Inflorescence
A head (capitulum) is a short dense spike in which the flowers are borne directly on a broad, flat peduncle, giving the inflorescence the appearance of a single flower, as in the dandelion ( Taraxacum ). Read More In angiosperm: Inflorescences

The composite inflorescence, capitulum, or flower head in Asteraceae assembles multiple flowers into a single, highly compressed structure. It is a very effective reproductive unit and with an apparent selective value, considered to be the key innovation for diversification of this largest family of flowering plants.
