Menyanthes is a monotypic genus of flowering plant in the family Menyanthaceae containing the single species Menyanthes trifoliata. The name Menyanthes comes from the Greek words menyein, meaning "disclosing", and anthos, meaning "flower", in reference to the sequential opening of flowers on the inflorescence. The North American form is often referred to as M. trifoliata var. minor Michx. It is known in English by the common names bogbean and buckbean.
