1. The persistent calyx is the green part forming a cup at the base of the fruit in Brinjal.
2. A persistent calyx is also seen in Tomato, Lady's finger.

It is a special inflorescence. A circular disc-like fleshy open receptacle bears pistillate flowers at the center and staminate flowers at the periphery. Eg: Dorstenia.

Thyrsus and Verticillaster

1. Cyathium
2. Hypanthodium
3. Coenanthium

1. Marginal (i) It is with the placentae along the margin of a unicarpellate ovary. (ii) Eg: Fabaceae.	4. Axile (i) The placentae arises from the column in a compound ovary with septa. (ii) Eg: Hibiscus, tomato lemon
2. Superficial (i) Ovules arise from the surface of the septa. (ii) Eg: Nymphaeaceae	5. Parietal (i) It is the placentae on the ovary walls or upon intruding partitions of a unilocular, compound Ovary. (ii) Eg: Mustard, Argemone, cucumber.
3. Free-central (i) It is with the placentae along the column in a compound ovary without septa. (ii) Eg: Caryophyllaceae, Dianthus, Primrose	6. Basal (i) It is the placenta at the base of the ovary. (ii) Eg: Sunflower(Asteraceae) Marigold

S.No	Spike	Spadix
1	It is an unbranched indeterminate          inflorescence with sessile flowers.	An inflorescence with fleshy axis bearing unisexual sessile flowers.
2	The flowers are exposed.	The flowers are covered by bract called spathe.
3	Flowers are generally bisexual. Eg: Wheat	Flowers are generally unisexual. Eg: Cocos

1. An inflorescence with the indeterminate central axis and pedicellate flowers arise from the common point of peduncle at the apex.
2. Compound umbel inflorescence is a branched umbel.
3. Each such umbel is called an umbellet.
4. Eg: Daucus carota (carrot).

1. It is a type of racemose inflorescence. In corymb, the main axis is not elongated.
2. The pedicel is of unequal length.
3. The order flowers have long pedicels and the young flowers show short pedicels. so all flowers appear at the same level.
4. Eg: Caesalpinia.

Placentation: The mode of distribution of placenta inside the ovary is called placentation. (Placenta bears the ovules.) It is of different types as follows:
1. Marginal: It is with the placentae along the margin of a unicarpellate ovary. Eg: Fabaceae.

2. Axile: The placentae arises from the column in a compound ovary with septa. Eg: Hibiscus, tomato, lemon.

3. Superficial: Ovules arise from the surface of the septa. Eg: Nymphaeaceae.

4. Parietal: It is the placentae on the ovary walls or upon intruding partitions of a unilocular, compound ovary. Eg: Mustard, Argemone, cucumber.

5. Basal: It is the placenta at the base of the ovary. Eg: Sunflower, Marigold.

6. Free-central: It is with the placentae along the column . in a compound ovary without septa. Eg: Caryophyllaceae, Dianthus, Primrose.

A Multiple or composite fruit develops from the whole inflorescence along with its peduncle on which they are borne.
a) Sorosis: A fleshy multiple fruit which develops from a spike or spadix. The flowers fused together by their succulent perianth and at the same time, the axis bearing them become fleshy or juicy and the whole inflorescence forms a compact mass. Eg: Pineapple, Jackfruit, Mulberry
b) Syconus: A multiple fruit which develops from hypanthodium inflorescence. The receptacle develops further and converts into fleshy fruit which encloses a number of true- fruit or achenes which develops from female flower of hypanthodium inflorescence. Eg: Ficus

Aestivation: Arrangement of sepals and petals in the flower bud.
1. Valvate: Margins of sepals or petals do not overlap but just touch each other.
Eg: Calyx in members of Malvaceae , Calotropis, Annona.
2. Twisted or Convolute or Contorted: One margin of each petal or sepal overlapping on the other petal
Eg: Petals of chinarose.
3.Imbricate: Sepals and petals irregularly overlap on each other; one member of the whorl is exterior, one interior and rest of the three having one margin exterior and the other.interior.
Eg: Cassia, Delonix. There are 3 types.
i Ascendingly imbricate
ii Quincuncial
iii Vexillary.
4.Quincuncial: It is a type of imbricate aestivation in which two petals are external and two internal and one petal with one margin internal and the other margin external.
Eg: Guava, calyx of Ipomoea, Catharanthus.
5.Vexillary: Large posterior petals both margins overlap lateral petals. Lateral petals other margin overlaps anterior petals. Eg: Pea, bean.

Schizocarpic Fruit:
This fruit type is 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.
1. Cremocarp: Fruit develops from bicarpellary, syncarpous inferior ovary and splitting into two, one-seeded segments known as mericarps. Eg: Coriander, Carrot.
2. Carcerulus: Fruit develops from bicarpellary, syncarpous superior ovary and splitting into four one-seeded segments known as nutlets. Eg: Leucas, Ocimum.
3. Lomentum: A leguminous fruit, constricted between the seeds to form a number of a one-seeded compartment, separating at maturity. Eg: Desmodium, Arachis, Mimosa.
4. Regma: Fruit develops from multicarpellary syncarpous ovary and splitting into one-seeded cocci. Eg: Ricinus, Geranium.

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.
