S.No.	Aggregate fruit	Multiple fruit
1	Aggregate fruits develop from a single fl ower having an apocarpous pistil. each of the free carpel develops into a simple fruitlet. A collection of simple fruitlets makes an Aggregate fruit. An individual ovary develops into a drupe, achene, follicle or berry	A Multiple or composite fruit develops from the whole infl orescence along with its peduncle on which they are borne
2	Eg: Polyalthia	Eg: Pineapple

This fruit type of intermediate between dehiscent and indehiscent fruit. The fruit instead of dehiscing rather splits into number of segments, each containing one or more seeds. They are of following types:
(a) Cremocarp: Fruit develops from bicarpellary, syncarpous, inferior ovary and splitting into two one seeded segments known as mericarps. e.g., Coriander and Carrot.
(b) Carcerulus: Fruit develops from bicarpellary, syncarpous, superior ovary and splitting into four one seeded segments known as nutlets. e.g., Leucas, Ocimum and Abutilon.
(c) Lomentum: The fruit is derived from monocarpellary, unilocularovary.Aleguminous fruit, constricted between the seeds to form a number of one seeded compartments that separate at maturity. e.g., Desmodium, Arachis and Mimosa.
(d) Regma: They develops from tricarpellary, syncarpous, superior, trilocular ovary and splits into one-seeded cocci which remain attached to carpophore. e.g., Ricinus and Geranium.

Cymose: Central axis stops growing and ends in a flower, Further growth is by means of axillary buds. Old flowers present at the apex and young flowers, at the base.
Types of cymose:
1. Simple cyme(Solitary): Determinate inflorescence consists of a single flower. It may be terminal or axillary. Eg: Hibiscus.
2. Monochasial Cyme (Uniparous): The main axis ends with a flower. From two lateral bracts, Only one branch grows further. It may be Helicoid or Scorpiod.
(a) Helicoid: Monochasial cyme in which axis develop on only one side and looks like a coil, at least during the stage of early development. Eg: Hamelia, Potato.

(b) Scorpioid: Monochasial cyme in which axes develop on alternate sides. Eg: Heliotropium.
3. Simple dichasium (Biparous):
(i) A central axis ends in a terminal flower; further growth is produced by two lateral buds.
(ii) Each cyme consists of three flowers of which, the central one is an old one. This is true cyme. Eg: Jasminum.

4. Compound dichasium: It has many flowers. A terminal old flower has lateral simple dichasial cymes on both sides. Each compound dichasium consists of seven flowers. Eg : Clerodendron.

5. Polychasial Cyme (Multiparous): The central axis ends with a flower. The lateral axes branches repeatedly. Eg: Nerium.

Racemose Inflorescence: Main axis is of unlimited growth and flowers are arranged in acropetal succession. Opening of flowers is centripetal.

Main Axis Elongated: Axis of the inflorescence is elongated and flowers may be pedicellate or sessile.
Types:
1. Simple Raceme: Unbranched Main axis has pedicellate flowers. Eg: Mustard.

2. Spike: Unbranched Main axis with sessile flowers. Eg: Achyranthes.

3. Spikelet: Small spike is called spikelet. The inflorescence axis has bracts at the base called glumes. Each flower has bract (lemma) and bracteole (palea). Eg: Sorghum.

4. Catkin: Pendulous spikes with long, drooping axis bearing small unisexual or bisexual flowers Eg: Acalypha hispida.

5. Spadix: Fleshy or thickened central axis with many unisexual flowers is acropetal succession. Entire inflorescence is covered by a brightly I coloured bract called spathe. Eg: Colocasia.

7. Panicle: A branched raceme is called panicle or compound raceme. Eg: Neem.

Main AXIS Shortened: Inflorescence shows reduced growth of central axis.
1. Corymb: Shorter pedicellate flowers at the top and longer pedicellate flowers at the bottom of the inflorescence. All flowers appear at the same level. Eg: Caesalpinia.
Compound Corymb: A Branched corymb is called compound corymb. Eg: Cauliflower.

2. Umbel: Pedicellate flowers arise from tip of inflorescence axis from a common point. Eg: Allium cepa.
Compound umbel: It is a branched umbel. Each smaller unit is called umbellet. Eg:Daucus carota, Coriandrum sativum.

Main Axis Flattened:
1. Head: The main axis is a flattened group of sessile or subsessile flowers arising on the flattened receptacle forms a head inflorescence surrounded by involucre. Eg: Asteraceae.
2. Compound Head: In Lagasca mollis the inflorescence axis is branched and each branch bears ahead inflorescence.
Types:

S.No	Homogamous head	Heterogamous head
1	Single kind of florets (ray or disc florets).	Both ray and disc florets are seen
2	Eg: Launaea	Eg. Tridax

The fruits are derived from single pistil where the pericarp is fleshy, succulent and differentiated into epicarp, mesocarp and endocarp. It is subdivided into the following.
(i) Berry: Fruit develops from bicarpellary or multicarpellary, syncarpous ovary. Here the epicarp is thin, the mesocarp and endocarp remain undifferentiated. They form a pulp in which the seeds are embedded. Eg: Tomato, Grapes, Brinjal.

(ii) Drupe: Fruit develops from monocarpellary, superior ovary. It is usually one seeded. Pericarp is differentiated into outer skinny epicarp, fleshy and pulpy mesocarp and hard and stony endocarp around the seed. Eg: Mango, Coconut.

(iii) Pepo: Fruit develops from tricarpellary inferior ovary. Pericarp turns leathery or woody which encloses, fleshy mesocarp and smooth endocarp. Eg: Cucumber, Watermelon, Bottle gourd, Pumpkin.

(iv) Hesperidium:Fruit develops from multicarpellary, multilocular, syncarpous, superior ovary. The fruit wall is differentiated into leathery epicarp with oil glands, a middle fibrous mesocarp. The endocarp forms distinct chambers, containing juicy hairs. Eg: Orange, Lemon.

(v) Pome: It develops from multicarpellary, syncarpous, inferior ovary. The receptacle also develops along with the ovary and becomes fleshy, enclosing the true fruit. In pome the epicarp is thin skin like and endocarp is cartilaginous. Eg: Apple, Pear.

(vi) Balausta: A fleshy indehiscent fruit developing from multicarpellary, multilocular inferior ovary whose pericarp is tough and leathery. Seeds are attached irregularly with testa being the edible portion. Eg: Pomegranate.
