The Orchidaceae are orchids, is a flower type that belongs to a family of monocotyledonous plants that are distinguished by the complexity of their flowers and their ecological interactions with pollinating agents and fungi with which they form mycorrhizas. The family comprises approximately 25,000 species, Its size varies from a few millimeters in length (certain species of the genera Bulbophyllum and Platystele) to gigantic aggregations that can weigh several hundred kilograms
In the same way, the size of its flowers varies, from the tiny ones of the genus. Even being a family whose flowers have a very different aspect between genres, its structure is homogeneous. As in other monocots, the perianth is trimer. It is formed by three external parts called sepals, two lateral and one dorsal, and three internal elements called petals, one of them modified in a lip or lip of larger size and more intense color than the rest
Orchids carry their flowers in different ways. Even within the same genus, different species can have different ways of arranging the flowers in inflorescences, which are indeterminate and, sometimes, reduced to a single flower, terminal or axillary
There are violets, white, yellow. In a nursery can also be found in variants in shades of pink, tabby, and of various sizes. However, one that is little known is the black orchid
