Flower cup

from Wikipedia, the free encyclopedia
Schematic representation of a flower with perigyner perianth (= "medium-sized" ovary):
1 cup shaped flowers ground (receptaculum) of the flower cups or Hypanthium forms
the second sepals (sepals)
3 petals (petals)
4. stamens (stamens)
5. Stamp ( Pestle)

The flower cup or hypanthium , also called the flower tube , is a cup-, bell- or tubular structure (axis piece) at the base of the flower , which is formed by the flower base . Usually at the base, but rarely on the side and at the top (mouth) of the flower cup as well as under it, sits the ovary . The remaining parts of the flower start at the top of the flower cup.

The term was first used by Heinrich Friedrich Link in 1824 . The term hypanthium means "under the flower". This can be explained by the fact that in the past the petals were thought to be the actual flower.
