Empetrum
''Empetrum'' is a genus of three species of dwarf evergreen shrubs in the heath family, Ericaceae. They are commonly known as crowberries and bear edible fruit. Species of ''Empetrum'' include: '' E. nigrum'' (crowberry) and its tetraploid subspecies ''E. nigrum'' ssp. ''hermaphroditum'', '' E. eamesii'' and '' E. rubrum''. Description All three species are evergreen mat forming shrubs, with small, light green needle-like leaves long. The flowers are small and either bisexual or dioecious. The fruit is a fairly dry berry. The plant has slender, wiry, spreading branches covered with short, narrow, stiff leaves, the margins of which are recurved so as to form a hollow cylinder concealing the hairy under face of the leaf, which protects against excessive loss of water from the leaf. Taxonomy The genus and related ones such as ''Ceratiola'' and '' Corema'' were for most of the 20th century classified in their own family Empetraceae, but molecular data, leaf ...

Empetrum Nigrum
''Empetrum nigrum'', crowberry, black crowberry, mossberry, or, in western Alaska, Labrador, etc., blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the Northern Hemisphere. Description ''Empetrum nigrum'' is a low growing, evergreen shrub with a creeping habit. The leaves are long, arranged alternately along the stem. The stems are red when young and then fade to brown. It blooms between May and June. It is usually dioecious. The flowers are small and not very noticeable, with greenish-pink sepals that turn reddish purple. The round fruits are drupes, wide, usually black or purplish-black but occasionally red. Its fruit persists for an average of 92.7 days, and bears an average of 7.8 seeds per fruit. Fruits average 86.5% water, and their dry weight includes 14.4% carbohydrates and 12.2% lipids, which is possibly the highest lipid content of any fleshy fruit in Europe.

Empetrum Rubrum
''Empetrum rubrum'', known as red crowberry or diddle-dee (Chilean Spanish: '' Murtilla de Magallanes''), is a species of plant in the heath family, Ericaceae. Distribution and habitat The species is distributed in Chile from Talca (35°S) to Cape Horn (55°S), in areas of adjacent Argentina, in the Falkland Islands, and in Tristan da Cunha. One of its northernmost natural growing places is Laguna del Maule. In Chile, it often grows in high-altitude areas close to the tree line and can tolerate alpine conditions such as strong winds and high sun exposure. In the Falkland Islands, it is the dominant species across large areas of lowland and upland dwarf shrub heath. Uses Its fruits are edible. In culture It is referenced in the Falkland Islands' unofficial national anthem.

Empetrum Eamesii
''Empetrum eamesii'', common name purple crowberry, is a North American species of dwarf evergreen shrub. Description The species forms a low-lying shrub with prostrate stems, forming a mat on the ground. Leaves are alternate or in whorls. Flowers are solitary near the tips of branches, each with 3 white petals. Fruits are spherical, pink or red in subsp. ''earnsii'', purple to reddish-purple in subsp. ''atropurpureum.'' Taxonomy All the United States and some of the Canadian material belongs to ''E.'' ''eamesii'' subsp. ''atropurpureum'' (Fernald & Wiegand) D.Löve, which has been regarded as a separate species by some authorities but not others. Distribution and habitat It is native to eastern Canada and the northeastern US. It has been reported from sand dunes, rocky outcrops, and alpine heath in Québec, Nova Scotia, Prince Edward Island, Maine, New Hampshire, Vermont, New York State, the Upper Peninsula of Michigan, Minnesota (Cook County), Newfoundland & Labrad ...

Ericoideae
Ericoideae is a subfamily of Ericaceae, containing nineteen genera, and 1,790 species, the largest of which is ''Rhododendron'', followed by Erica. The Ericoideae bear spiral leaves with flat laminae. The pedicel is articulated and the flowers are pendulous or erect, and monosymmetric, with an abaxial median sepal. The carpels are free and the anthers lack appendages. The capsule is septicidal.

Tristan Da Cunha
Tristan da Cunha (), colloquially Tristan, is a remote group of volcano, volcanic islands in the South Atlantic Ocean. It is one of three constituent parts of the British Overseas Territories, British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, with its own constitution. The territory consists of the inhabited island Tristan da Cunha, which has a diameter of roughly and an area of ; the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. , the main island had 250 permanent inhabitants, who all carry British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel of a weather station on Gough Island. As there is no airstrip on the island, the only way of travelling to or from Tristan is by ship.
