Orchidaceae: A Guide to the Orchid Flower Family

Orchidaceae is normally called the Orchid family. It is a widespread and morphologically diverse family of monocots that is in the order of Asparagales. Scientists think that it is presently the biggest family of flowering plants with up to 26,000 accepted species across 880 genera. The quantity of species of orchids is presently double that of the number of species of birds and even four times the number of species of mammals. It makes up between six and eleven percent of seed plants.

The biggest genera in the Orchid family are called Bulpophyllum, which has 2000 species. The next-largest genera are called Epidendrum with 1500 species. The third-largest genera are called Dendrobium at 1400 species. The fourth-largest genera are referred to as Pleurothallis, and they number 1000 species. The name “orchid” actually stems from a Greek word that literally means “testicle,” and the shape of the orchid’s root accounts for this naming etymology. The following list of links will provide even more information about the Orchid family.
