Orchis

Orchis is a genus in the orchid family (Orchidaceae), occurring mainly in Europe and Northwest Africa, and ranging as far as Tibet, Mongolia, and Xinjiang. The name is from the Ancient Greek ὄρχις orchis, meaning "testicle", from the appearance of the paired subterranean tuberoids.

Description
These terrestrial orchids have root tubers instead of pseudobulbs. They are extremely diverse in appearance. They produce an erect stem. The inflorescence is a cylindrical to globular spike, 5 – long, with yellow, red to purple flowers. They start flowering at the base, slowly progressing upwards, except for the Monkey orchid (Orchis simia), which flowers in reverse order.

The original genus Orchis used to contain more than 1,300 names. Since it was polyphyletic, it has been divided by Pridgeon et al., into several new genera (see Reference): Ponerorchis, Schizodium, Steveniella. They can be found in tropical Rainforest and semi-desert regions, near the seashore and in the tundra. The majority of neotropical orchid species can be found in southern Central America, northwest South America
