(crowberry), a genus of plants of the family Empetraceae. The plants are low evergreen monoecious or dioecious shrubs; the leaves are narrow and thick and have edges that curve down and almost meet. The flower is small, axillary, and trimerous and has a double perianth; there are three stamens and a radial stigma, and the superior ovary is six-, nine-, or 12-celled. The fruit is a berry-like drupe with a watery and slightly sweet juice. There are only a few species of Empetrum (18, according to some data), which grow over the entire Holarctic region and in the antarctic region (the Chilean Andes, Tierra del Fuego, the Falkland Islands, and Tristan da Cunha). The plant is found on moss, moss-lichen, and rocky tundras and in sphagnum bogs—and more rarely on sandy spits and dunes, in forests, and in the alpine belt. The best-known species is crowberry (E. nigrum). The berries of Empetrum are sometimes used as food, especially in regions where there are few other juicy berry fruits.

These results demonstrate that caribou bone collagen is a reliable and accurate dating material, but more importantly, they indicate that seeds from edible berries (Rubus chamaemorus and Empetrum nigrum) also produce reliable dates that are statistically indistinguishable from those on caribou.
Previous studies of Empetrum rubrum (Rossow, in Correa 1999) described their leaves as narrow and longitudinally ridged on their abaxial surface.

Evergreen, ericaceous sclerophyllous shrubs and dwarf shrubs occur mostly in low-pH wetlands, and several species, such as Vaccinium vitis-idaea and Empetrum nigrum also have a distribution along broad soil-moisture gradients from bogs and mesic tundra, to dry forests and arctic heaths (Larsen 1982, Moore 1981).
There were five cover types in our study area: 1) shrub dominated by creeping pine Pinus pumila, 2) dwarf shrub dominated by alpine azalea Loiseleuriaprocumbens, Arcterica nana and black crowberry Empetrum nigrum var.
