1

Position of floral part on thalamus

HYPOGYNOUS: Gynoecium is highest
Ovaries are superior
MUSTARD, CHINA ROSE,Brinjal,Petunia

PERIGYNOUS: Centre, other at rim or periphery to thalamus
Ovaries are Half inferior
PLUM, RISE, PEACH

EPIGYNOUS: Ovaries are enclosed complete, fused, other part are above
GUAVA, CUCUMBER, BITTERGOURD, Sunflower ray floret

2

Calyx
Corolla
Androecium
Gynoecium

Sepal
Petal
Stamen
Csrpel

3

Types of calyx

Gamosepalous sepal United
Polysepalous- sepal free

4

Corolla shape

Tubular, bell shape, funnel shape, wheel shape

5

Aestivation

Arrangements of sepal, Petal in floral bud with respect to other member of the same whrol
Valvate
Twisted
Imbricate
Vexillary

6

Valvate

Margin just touch eachother, no overlapping
CALOTROPIS

7

Twisted

Sepal, peal overlap adjacent sepal, Petal
CHINA ROSE, LADIES FINGER, COTTON

8

Imbricate

Margin overlap but in different directions
CASSIA, GULMOHUR

9

Vexillary

Large (standard) overlap smaller lateral (wings) overlap analyst anterior (keel)

10

Androecium

Male
Inner to corolla
Stamen- anther, filament
Length of filament may varry like in Salvia, mustard

11

Sterile stamen

Staminode

12

Adhesion of stamen

Stamen attached with Petal: epipetalous, BRINGAL
With preinath: epiphyllous: LILY

13

Adhesion of stamen

Free stamen- polyandrous
1 bundle: monoadelophous, China Rose
2 bundle: diadepholus, pea
More: polyandrous, Citrus

14

Gynoecium

Female
Free calpel, lotus, rose- Apocarpous
Fused carpel- mustard, tomato- synchronous

15

Ovary

Basal, swollen
Chamber of ovaries- Loculi
1 C- unilocular
2- bi
3-tri
Ovules are borne in these chambers

16

Placentra

Marginal
Axile
Parietal
Free central
Basal

17

Marginal

ridge along vertical suture of ovary
Ovules are borne in 2 alternate rows
Pea

18

Axile

Axile position, ovules are located in multilocular ovary
China Rose, tomata, lemon

19

Parietal

One chamber ovary becomes 2 chamber due to false septum
Ovule develop on innerwall on peripheral
MUSTARD, ARGEMONE

20

Free central

Ovules are borne on central axis, septa absent in ovary
PRIMROSE, DIANTHUS

21

Basal

The placenta develops at base, single ovule in placenta
SUNFLOWER, MARIGOLD

22

Parthenocarpic fruit

Fruits without fertilisation
Banana

23

Part of fruit

Fruit wall: pericarp develops from walls of ovary
Dry or fleshy
If fleshy:
Epicarp outer
Mesocrap middle
Endocarp innermost

Seeds develop from ovules:
Grapes,banana
In apple, pear fruit formation with other part

24

Simple fruit
Aggregate fruit
Multiple fruit

Syncarpous ovary,
Dry fruit, succulent
Polycarpellary, Apocarpous: Strawberry, RaSbErry
Entire inflorescence, JACKFRUIT, mulberry, pineapple, Ficus

25

Dry fruit

Dehiscent: Legume or pod: PEA, Silqua or silicula: BRASSICACEAE, capsule: DATURA
Burst automatically and discharge seed

Indehiscent: Cypsela(sunflower), Caryopsis(wheat, maize, rice), Scheme(mirabillis) nut(litchi)
Do not burst automatically, liberation of seed, decomposition, destruction of pericarp

26

Succulent/ fleshy fruit

Drupe: mango, coconut
BERRY: Tomato, guava, grapes
Peepo: Cucumber
POME: Apple, Pear
Hesperidium: orange, Citrus
Balausta: Pomegranate

27

Drupe

One seed fruit, diff into epicarp, meso, endo(hard, stony)
Mango: epi is skin
Meso is juicy p, edible

Coconut: Coco's nuctifera: meso is fibrous, so fibrous drupe
Walnu( Jutland regia)

28

Parthenocarpic fruit

Fruit without fertilisation
Banana

29

Seed
Dicot seed

Seed coat + embryo
Embryo: embryo axis + 1( wheat maize) or 2cotyledons ( gram, pea)

,, + Endosperm

30

Seed coat

Develops from interguments of ovules
2 layer: outer testa, inner tegmen
Hilum is scar in seed coat where seed is attached to fruit
Above hilum is micropyle small pore

31

Embryo

Most important part of seed
2 cotyledons, fleshy, food materials
End of axis are radical, plumule

32

Endosperm

Double fertilisation
Storage eg castor
But in bean, gram, pea not present,

33

Monocotyledons seed

In seed of cereal such as maize, seed coat is membranous
Endosperm, embryo are below it.
Orchids are no endosperm
Protenatious structure: Aleutone layer
Embryo is small, at groove at endosperm end.
Large, shield shaped cotyledons: scutellum, short axis plume, radicle
Plumele sheath: Coleptile, Radicle: coleorrhiza

34

Perispermic seed

Stays in seed, perisperm
Piper nigrum (black pepper)

35

Brassicasea

Inflorescence corumb, corymbose- raceme
Flower tetramerous
Cruciform corolla
Tetradynamous condition, sometime didynamous
Bicarpellary, syncarpous, superior ovaries, unilocular but binocular due to replum, partiesl platform, stigma Bivins
Fruit is siiqua, silicula

36
