Or"chis (?), n.; pl. Orchises (#). [L., fr. Gr. a testicle, the orchis; -- so called from its tubers.]
A genus of endogenous plants growing in the North Temperate zone, and consisting of about eighty species. They are perennial herbs growing from a tuber (beside which is usually found the last year's tuber also), and are valued for their showy flowers. See Orchidaceous.

⇒ The common names, such as bee orchis, fly orchis, butterfly orchis, etc., allude to the peculiar form of the flower.
