3. Flower Parts
The receptacle is the point at which the floral parts attach to the tip of the specialized stem bearing the flower. The receptacle is often somewhat enlarged.
Sepals make up the outer ring of floral parts; collectively, they are called the calyx. They are often green in color, though some flowers (fuchsia and iris, for example) have brightly colored, petal-like sepals.

4. Flower Parts
Petals form the next circle of flower parts, just inward from the sepals. If a blossom is showy, chances are it's the petals you notice. Petals may be separate, as in camellia and rose, or united in a tubular, cupped, or bell-like shape, as in rhododendron and petunia. Collectively, the petals are called the corolla; corolla and calyx together are known as the perianth.
Stamens, positioned inward from the petals, contain the male reproductive elements. A typical stamen consists of a slender stalk, the filament, topped by an anther, which is usually yellow in color. The anther contains grains of pollen, the male element needed to fertilize the flower.

5. Flower Parts
Pistils, found in the flower's center, bear the female reproductive parts. Each pistil typically consists of an ovary with a stalklike tube (the style) rising from it. The style is topped by a stigma, which receives the pollen. The ovary contains one or more ovules; following pollination and fertilization, these develop into the plant's seeds

7. Aestivation

8. Aestivation
imbricate: of perianth parts, having the edges overlapping in the bud. valvate: of perianth parts, meeting edge to edge in the 0bud, not overlapping convolute: of the arrangement of corolla lobes in a bud, a form of imbricate aestivation in which each segment has one edge overlapping the adjacent segment, like a furled umbrella

11. Symmetry
This means that the flower has a radial symmetry — it can be divided into two equal halves by two or more planes (5 here, shown by the yellow lines).

13. Symmetry
Here again, the flower can be cut into two symmetrical halves by only one plane, along the red line.

14. Placentation
The arrangement of ovules within the ovary is known as placentation. The placentation are of different types namely, marginal, axile, parietal, basal, central and free central.

17. Placentation

18. a. Marginal placentation:
The arrangement of ovules on the placenta inside the ovary is called placentation. There are several types of palcentation
a. Marginal placentation:
In this type, the ovary is monocarpellary, monolocular and the placenta is on the ventral suture. The ovules are attached to the placenta which is on the margin. e.g. Beans, Pea, etc

19. Placentation b. Axile placentation :
In this type, the ovary has two or more carpels, syncarpous, and has two or more locules. The ovules are borne at or near the centre on the axis formed by the union and fusion of the septa (partitions) and usually in vertical rows. e.g., Apple, Hibiscus etc.

20. c. Free Central placentation: d. Free basal placentation:
In this type the ovary is monolocular, wherein the ovules are borne on a central axis that reaches the top of the ovary. e.g., Primula, Sandal Wood.
d. Free basal placentation:
Similar to free central but the placental column does not reach the top of the ovary. e.g., Portulaca, Celosia.

21. Pariental Placentation:
In this type, the ovary has two or more carpels, and is syncarpous, and monolocular. Here there are as many placentae as the number of carpels and the ovules are attached to those placentae at the periphery. e.g., Cucurbita, Argemone

22. f. Apical placentation:
e. Basal Placentation:
In this type, the ovary is monolocular. The ovules are few or reduced to one and borne at the base of the ovary. The ovule when solitary often fills the ovary cavity. e.g., Sunflower.
f. Apical placentation:
The ovary is monolocular. The one or two ovules are borne at the roof of the ovary. e.g., Morus

27. Plant condition
Synoecious – a sexual condition in which the flowers on a plant are all perfect
Monoecious – both staminate and carpellate flowers occur on the same individual
Dioecious – staminate and carpellate flowers
occur on separate individual

Ø  Petals (Collectively the Corolla, symbolized as C)
Ø  Stamens (Collectively the Androecium, symbolized as A)
Ø  Carpels (Collectively the Gynoecium, symbolized as G)

31. Carpels (Collectively the Gynoecium, symbolized as G)
Considering the above factors in Hibiscus rosa-sinensis following features are observed:
Bracteate flowers, represented as Br.
Epicalyx is present below calyx, indicated as Brl.
Actinomorphic symmetry is represented as Φ
Flowers are basically bisexual represented as 
5 sepals which are fused, represented as K(5)
  5 petals which are free, represented as C5
  Stamens are numerous and filaments of stamens are fused, represented as A(∞)
5 Carpels, fused and ovary is superior, represented as G(5)

32. Floral Diagram of Hibiscus
Floral Diagram is a graphical representation of parts and symmetry of a flower.
Keeping in mind the above Floral formula we can derive the following Floral diagram for Hibiscus:
