Rubus chamaemorus (Greek chamai "on the ground", moros "mulberry") is a rhizomatous herb native to alpine and arctic tundra and boreal forest, producing amber-colored edible fruit similar to the raspberry or blackberry. English common names include cloudberry, bakeapple (in Newfoundland and Labrador), knotberry and knoutberry (in England), aqpik or low-bush salmonberry (in Alaska - not to be confused with true salmonberry, Rubus spectabilis), and averin or evron (in Scotland).Unlike most Rubus species, the cloudberry is dioecious, and fruit production by a female plant requires pollination from a male plant.The cloudberry grows to 10–25 cm high. The leaves alternate between having 5 and 7 soft, handlike lobes on straight, branchless stalks. After pollination, the white (sometimes reddish-tipped) flowers form raspberry-sized berries. Encapsulating between 5 and 25 drupelets, each fruit is initially pale red, ripening into an amber color in early autumn.
