The structure of all orchid flowers is similar to that of many other monocot plants, Here the tulip is taken as an example. With her encloses a flower envelope – consisting of three outer and three inner petals – the other organs. These are three outer and three inner stamens and the ovary, which in turn consists of three carpels. The diagram opposite illustrates the structure in the scheme.
This basic plan is typically changed in one form for the orchid flowers, as it does not occur in other plant families. The three outer leaves of the perianth – referred to as sepals or sepals – usually differ in shape, often also in the color of the inner ones. Of these, the two on the side are equal to each other, they are called petals or flowers – or. Petals. The third almost always differs in size, Shape and color and is called labellum or lip. This labellum is usually conspicuous and varied – such as. bei Cattleya; but it can also be inconspicuous and small, without any special color effect. Compared to other flowers, the internal organs are largely changed. Usually five stamens are completely stunted or. not trained, only a single one of the outer circle is fully developed and carries the pollen. It is not free from the usual type, but is with the stylus to a unified whole, the pillar, grown together. The anthers are located on top of this column or column. It is separated from the underlying scar by a sterile scar flap.
