Capitulum Or Head Inflorescence (Lecture 13) In Hindi/Urdu.

A capitulum, also known as a composite or flower head, is a unique type of inflorescence with the following key features:

1. Main Axis:
The main axis, or receptacle, is the flattened or slightly convex structure that bears the individual flowers.
The receptacle exhibits a determinate growth pattern, meaning it stops growing after a certain point.

2. Flower Arrangement:
The flowers are densely packed and arranged in a tight, compact cluster on the receptacle.
The flowers can be of two types: ray flowers (on the outer ring) and disc flowers (in the center).

3. Floral Structure:
The individual flowers are small and often inconspicuous.
The flowers may have showy, strap-like petals (ray flowers) or less conspicuous tubular petals (disc flowers).
The flowers are typically arranged in a radially symmetrical pattern on the receptacle.

4. Examples:
Some common examples of plants with capitulum inflorescences include:
Sunflowers (Helianthus spp.)
Daisies (Bellis spp.)
Dandelions (Taraxacum spp.)
Chrysanthemums (Chrysanthemum spp.)

The capitulum inflorescence is a distinctive feature of the Asteraceae (daisy) family, which is one of the largest plant families. The compact arrangement of small flowers on the receptacle is an adaptation for efficient pollination by insects and other animals.

Understanding the structure and characteristics of the capitulum inflorescence is crucial for the identification and classification of many economically and ecologically important plant species.
