In Botanical, a petal is one of the coloured elements Foliacé S, whose whole composes the Corolle of a Fleur. This one is the internal part of the perianth which includes/understands the two sterile verticils of a flower. The petals are generally different from the Sépale S. When they are of identical aspect, one speaks about Tépale S. In a complete flower, the petals constitute the most visible and coloured part which surrounds the part fertile. The number of the petals is an indicator of the classification of the plants: one generally counts of them four or five (generally) at the Dicotylédone S, and three (or a multiple of three) at the Monocotylédone S.

One notes important variations of the shape of the petals among the plants with flowers. The petals can be welded at the base, forming a “floral tube”. At certain species, the petals are almost entirely welded, forming a kind of ballot box or of bell surrounding the Gynécée and carrying the cheesecloth S. It is the case for example Gentiane S.

The flowers of certain species either do not have petals of the whole, or carry very reduced petals. They are called “apétales”. Example of flowers with very reduced perianth can be found in particular at the kitten trees (Fagacée S for example) or at the Poacée S (graminaceous).

The petals are generally the apparent part of the flower, and the whole of the petals, or Corolle can have a radial or bilateral symmetry. If all the petals are about identical in the face and form, the flower is known as regular or actinomorphic (what means of radiant form). It is the case of the Bouton of gold for example. Many flowers which have a symmetry compared to a plan are known as irregular or zygomorphes. At the irregular flowers, of another floral parts can also lose their regular form, but in fact the petals show the greatest modifications compared to radial symmetry. Examples of flowers zygomorphes can be found among the Orchidée S and the Fabacée S (Papilionacées).

At the plants of the family of the Astéracée S (Made up), the peripheral florets of the capitulates have often a ligula very developed simulating a petal, as at the daisy for example. Actually these florets, which are the elementary flowers, have a corolla welded out of tube with its part inferior, the ligula being a side outgrowth.

---- The teenagers “one by one thin out the leaves of” the ligulas of Marguerite to test to them Sentiment S Amour them.

---- In Kitchen, one calls petals grains of Céréale (Maïs, Blé, Orge) crushed and dried used in various food preparations. Example: corn petals frozen with the Sugar.
