MARSH EISTUS, or Wild Rosemary. A genus of the monogynia order, belonging to the decidua class of plants; and in the natural method ranking under the 18th order, Bicornes. The calyx is quinquifid; the corolla plain and quinquepartite; the capsule quinquelocular, and opening at the base. There is but one species, viz. the palustre, with very narrow leaves. This grows naturally upon bogs and mosses in many parts of Yorkshire, Cheshire, and Lancashire; rising with a slender shrubby stalk about two feet high, dividing into many slender branches, garnished with narrow leaves, not much unlike those of heath. The flowers are produced in small clusters at the end of the branches, and are shaped like those of the strawberry-tree, but spread open wider at top. These are of a reddish colour, and in the natural places of their growth are succeeded by seed-vessels filled with small seeds which ripen in autumn.—This plant is with great difficulty kept in a garden; for as it naturally grows upon bogs, unless the plants have a similar soil they will not thrive. They must be procured from the places of their origin. their growth, and taken up with good roots, otherwise they will not live.
