Lin. Sp. Pl. 561; cistus ledon, rosmarinum sylvestre, marsh cistus, or wild rosemary, rises with a slender shrubby stalk about two feet high, dividing into many slender branches, garnished with narrow leaves, not much unlike those of the heath. The flowers are produced in small clusters at the end of the branches, shaped like those of the strawberry tree, but spreading wider at the top, of a reddish colour, and succeeded by seed vessels, filled with small seeds which ripen in autumn. It grows naturally upon bogs and mosses in many parts of Yorkshire, Cheshire, and Lancashire; hath a strong though fragrant smell, and is bitter to the taste. It.is considered to be possessed of sedative powers, from its narcotic and inebriating qualities; and has been said, without any previous evacuation by emetics, and purgatives, alone to cure the dysentery.
