Bird's-nest; a genus of the monotropia order, belonging to the decandra class of plants. There are two species; of which the only remarkable one is the hippopithys, a native of Britain and some of the more northerly kingdoms of Europe. It is about five inches high, having no other leaves than oval scales, and terminated with a nodding spike of flowers, which in the feeding-state becomes erect: the whole plant is of a pale-yellow colour, smelling like the primrose, or like beans in blossom. The country-people in Sweden give the dried plant to cattle cattle that have a cough.
