The document discusses the different types of inflorescences found in angiosperms. It identifies 8 main types: recemose, spadix, catkin, corymb, panicle, umbel, cymose, and head inflorescences. Each has distinct characteristics, such as spadix having small, densely packed flowers surrounded by a spathe, while panicles are branched racemes. The inflorescence structures play an important role in the reproduction of flowering plants.

2. ● Introduction
● Inflorescence in angiosperms :
The arrangement and process of a flowering plant which produce flowers
& having seed enclosed within their fruit(angiosperms).
● Angiosperms :
Angiosperms are the largest group of plant within plant
kingdom which produce flowers & having seed enclosed
within their fruits .

3. Different types of inflorescence in angiosperms-
1. Recemose(Receme) Inflorescence
2. Spadix Inflorescence
3. Catkin Inflorescence
4. Corymb Inflorescence
5. Panicle Inflorescence
6. Umbel Inflorescence
7. Cymose(Cyme) Inflorescence
8. Head(Capitulum) Inflorescence

4. ● Indeterminate Raceme: The main axis continues to grow, and flowers are
borne on lateral stalks (pedicels).
● Examples- snapdragon (Antirrhinum majus).
● Determinate Raceme: The main axis terminates in a flower, and no further
growth occurs.
● Example- mustard plant (Brassica juncea).
1. Recemos Inflorescence

5. 7. Cymose Inflorescence
● Indeterminate Cyme: The central or apical flower opens first, and further
flowers open in a basipetal (from apex to base) order.
● Determinate Cyme: The terminal flower opens first, and no more flowers
develop after that. Examples include the trillium plant.

6. 2.Spadix Inflorescence
● A spike with small, densely packed flowers on a thick, fleshy axis,
often surrounded by a modified leaf called a spathe.
● Examples include the peace lily (Spathiphyllum)
Peace Lily

7. 3. Catkin Inflorescence
● A spike of unisexual, apetalous flowers, typically drooping.
● Examples - Willow (Salix) catkin
4. Corymb Inflorescence
● Flat-topped or convex inflorescence where the
lower flowers have longer pedicels than the
upper ones.
● Example- Yarrow (Achillea millefolium).

8. 5.Panicle Inflorescence
● Branched raceme where each branch has its own lateral branches.
● Examples- Oat plant (Avena sativa).
6. Umbel Inflorescence
● Flowers arise from a common point, giving the appearance of an
umbrella.
● Examples- carrot (Daucus carota).

9. 7.Cymose Inflorescence
● Indeterminate Cyme: The central or apical flower opens first, and
further flowers open in a basipetal (from apex to base) order.
Examples include the forget-me-not (Myosotis).
● Determinate Cyme: The terminal flower opens first, and no more
flowers develop after that. Examples- trillium plant.

10. 8.Head (Capitulum) Inflorescence
● Dense, compact inflorescence with sessile flowers, characteristic of
plants in the Asteraceae family (e.g., sunflowers).

11. Conclusion
● Inflorescence plays a vital role in the reproductive strategy of
angiosperms, genetic diversity and resource allocation.
● Inflorescence increase risibility, attracting pollinators by procreding a
concentrated display of flowers.
