The orchid family is the largest family of flowering plants and its name is derived from the genus orchis. It has a large number of species, about 4 times that of the number of species for mammals. Orchids are found in the tropics or sub tropics.
kingdom:plantae
order: asparagales
family: orchidacea
Most orchids are perennial epiphytes (An epiphyte is an organism that grows upon or attaches to a living plant) and grow on trees. Like most plants, orchids have leaves, roots, stems and flowers.
The structure of the leaves of orchids is dependent on its habitat. For example, if it grows in a dry habitat, the leaves would be thick and leathery and the laminas covered by a waxy cuticle to prevent excessive water loss.
Orchids are herbs and thus do not have a woody stem.
