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.

The inflorescence is an involucrate capitulum (see below for more information).. The most common characteristic of these plants is the presence of a capitulum, or floral head, containing a number of small individual flowers, termed florets.. This diagram shows typical parts of a Compositae (or Dahlia) flower..

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.

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.
Inflorescence Classification, Types, Significance, Examples
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.

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. Use the information above to identify the inflorescence types present in your lab. In the space below, make a sketch of each inflorescence type that will help you make these.

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.
Centripetal arrangement of florets Capitulum/Head InflorescenceTagetes (Fam. Asteraceae) NEET
Capitulum - Inflorescence axis is flattened to form a receptacle wherein ligulate ray florets and tubular disc florets develop in a centripetal manner. Example - Tridax. Sketch a diagram of a flower of every inflorescence. Label different parts after identification. Position of the ovary is noted corresponding to the floral parts.

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).

-- Floral Displays The vast majority of flowering plants possess flowers in clusters called an inflorescence. These clusters facilitate pollination via a prominent visual display and more efficient pollen uptake and deposition. One modification of the basic raceme is to make it compound compound Raceme Panicle
The Inflorescence
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.

10. Capitulum or Head or Anthodium: This is the characteristic inflorescence of the family Compositae. The rachis forms a flattened, more or less convex receptacle on which the florets are arranged in a centripetal order. The whole capitulum is surrounded by an involucre of bracts at the base and each floret usually has its individual scaly bract.
Plant Science (Botany) Multiple Questions and Answers
When the main axis of raceme is branched and the lateral branches bear the flowers, the inflorescence is known as compound raceme or panicle, e.g., neem (Azadirachta indica), gul-mohar (Delonix regia), etc. The main axis of the inflorescence together with the latest axes, if present, is termed as the peduncle.
