The Sepals are small or absent.
The Sepals are larger than the fruit itself.
Each of the flowers consists of two dozen petals,
which are actually Sepals.
With the beginning of flowering on the plant is formed wrapped sepal.
In the first floral whorl only A-genes are expressed, leading to the formation of Sepals.
Beneath the petals are five Sepals or in the case of some Rosa sericea, four.
Anemone is the owner of a simple perianth,
consisting only of petals, and Sepals are absent.
known as an operculum which is composed of the fused Sepals or petals, or both.
It is single, located at the top of a ribbed stem and
has four outer green(Sepals) and four inner yellow-green petals.
Petals in number 4, on the top form a small helmet,
narrowed at the base of the claw, Sepals are quite dense.
Next, the stamen dries up and the fruit quickly develops underneath the Sepals[which ultimately become the brown bits opposite
the stem on a ripe apple].
In early July, flowers with large Sepals reveal absolutely white flowers,
which become pink after a few days, and after three weeks they acquire a rich red color.
For example, when there is a loss of B-gene function,
mutant flowers are produced with Sepals in the first whorl as usual,
but also in the second whorl instead of the normal petal formation.
