(from Balthasar Besler an apothecary at Nuremberg, author of a book intitled Hortus Eystetensis,) a genus of the angiosperma order, belonging to the didynamia class of plants. Of this genus there are three species, the melittiflora, with branching footstalks and oval leaves; the lutea, with simple foot-stalks growing in clusters, and spear-shaped-leaves; and the crista, with stalks growing single, and a five-leaved involucrum. All these are natives of the warm parts of America, and cannot be preserved in this country without artificial heat. But as they are remarkable neither for beauty nor any other property, we forbear any particular description.
