(Rubus chamaemorus), a plant of the family Rosaceae; it is of the same genus as the raspberry, blackberry, and stone bramble. An herbaceous perennial, it is 5–20 cm tall and has a long, creeping rhizome and erect annual stems. The leaves are reniform, wrinkled, five-lobed, and dark green. The flowers are unisexual (the staminate and pistillate flowers are on different plants), solitary, white, and large. The fruit is a multiple drupe consisting of red and, later, orange drupelets with a pleasant aroma. The cloudberry grows mainly in tundra and taiga zones of the northern hemisphere on mossy marshes and swampy forests. It grows in the northern European USSR and forms large thickets in Siberia and the Soviet Far East. The fruits contain sugar (3–6 percent), citric and malic acids, tannins, and pectins; they are used fresh in food and in the preparation of jams and beverages. The cloudberry produces a significant quantity of nectar.
