Arctous is a genus of plants [1] referred to by the common name "bearberry", [2] a name sometimes shared with certain species of the related genus Arctostaphylos , in particular, A. uva-ursi . Although the two genera are related, certain characters, such as deciduous, marcescent leaves, rugose-reticulate venation, and finely-toothed leaves are more typical of Arctous than Arctostaphylos.

Species within the genus include the following:

Manzanita Common name for many species of genus Arctostaphylos

Manzanita is a common name for many species of the genus Arctostaphylos. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from Southern British Columbia and Washington to Oregon, California, Utah, Arizona, New Mexico, and Texas in the United States, and throughout Mexico. Manzanitas can live in places with poor soil and little water. They are characterized by smooth orange or red bark and stiff, twisting branches. There are 105 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom in the winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible.

Bearberry Common name for several plant species

Bearberries are three species of dwarf shrubs in the genus Arctostaphylos. Unlike the other species of Arctostaphylos, they are adapted to Arctic and Subarctic climates, and have a circumpolar distribution in northern North America, Asia and Europe.

<i>Arctostaphylos</i> Genus of flowering plants in the heath family Ericaceae

Arctostaphylos is a genus of plants comprising the manzanitas and bearberries. They are shrubs or small trees.

<i>Arctostaphylos uva-ursi</i> Species of fruit and plant

Arctostaphylos uva-ursi is a plant species of the genus Arctostaphylos widely distributed across circumboreal regions of the subarctic Northern Hemisphere. Kinnikinnick is a common name in Canada and the United States. Growing up to 30 centimetres in height, the leaves are evergreen. The flowers are white to pink and the fruit is a red berry.

<i>Arctous alpina</i> Species of flowering plant

Arctous alpina, the alpine bearberry, mountain bearberry or black bearberry, is a dwarf shrub in the heather family Ericaceae. The basionym of this species is Arbutus alpinaL..

A tautonym is a scientific name of a species in which both parts of the name have the same spelling, such as Rattus rattus. The first part of the name is the name of the genus and the second part is referred to as the specific epithet in the International Code of Nomenclature for algae, fungi, and plants and the specific name in the International Code of Zoological Nomenclature.

Arbutin Glycoside

Arbutin is a glycoside; a glycosylated hydroquinone extracted from the bearberry plant in the genus Arctostaphylos among many other medicinal plants, primarily in the family Ericaceae. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. Arbutin is therefore used as a skin-lightening agent. Very tiny amounts of arbutin are found in wheat, pear skins, and some other foods. It is also found in Viburnum opulus and Bergenia crassifolia. Arbutin was also produced by an in vitro culture of Schisandra chinensis.

<i>Grevillea alpina</i> Species of shrub in the family Proteaceae from Victoria and southern New South Wales.

The Australian flowering shrub Grevillea alpina has several common names, including mountain grevillea, alpine grevillea, and cat's claws. It is not limited to alpine environments, and in fact is less common at high elevation than low. The species is variable in appearance, with five general forms described: small-flowered, Grampians, Northern Victorian, Goldfields, and Southern Hills forms. It is found in dry forests and woodlands across Victoria and into southern New South Wales. Some forms of the plant are low to the ground, and some become a spreading shrub. The flowers come in many colours, from white to green to shades of red and pink, or a pattern of several colours. The curled flowers are 1 to 3 centimetres in length. It is attractive to nectar-feeding insects and birds.

<i>Vaccinium crassifolium</i> Berry and plant

Vaccinium crassifolium, the creeping blueberry, is a species of Vaccinium in the heath family. It is native to the four southeastern U.S. states of Virginia, North Carolina, South Carolina, and Georgia. It is an evergreen shrub with shiny dark green to bronze leaves.

Mountain cranberry is a common name for several plants and may refer to:

<i>Amara alpina</i> Species of beetle

Amara alpina is a species of beetle of the genus Amara in the family Carabidae. It is native to northern parts of Europe and Asia. It was first described by the Swedish entomologist Gustaf von Paykull in 1790.

<i>Arctostaphylos bakeri</i> Species of flowering plant

Arctostaphylos bakeri is a species of manzanita known by the common name Baker's manzanita. It is endemic to Sonoma County, California, where it grows in the chaparral and woodlands of the North Coast Ranges. It is sometimes a member of the serpentine soils flora.

<i>Arctostaphylos densiflora</i> Species of flowering plant

Arctostaphylos densiflora, known by the common name Vine Hill manzanita, is a very rare species of manzanita. It is endemic to Sonoma County, California, where it is known from only one extant population of 20 to 30 individual plants. These last wild members of the species are on land near Sebastopol which is owned and protected by the California Native Plant Society. In addition, there are five to ten plants of this manzanita taxon growing on private property about a mile away. The local habitat is mostly chaparral on sandy shale soils.

<i>Arctostaphylos obispoensis</i> Species of tree

Arctostaphylos obispoensis is a species of manzanita, known by the common names bishop manzanita and serpentine manzanita, endemic to California.

<i>Philedonides lunana</i> Species of moth

Philedonides lunana, also known as the heath tortrix and Walker’s Lanark tortrix, is a moth of the family Tortricidae. It was first described by Carl Peter Thunberg in 1784 and is found in most of Europe.

Bearberry is three species of shrubs in the genus Arctostaphylos.

<i>Arctostaphylos rubra</i> Species of flowering plant

Arctostaphylos rubra is a species of flowering plant in the heath family and the genus Arctostaphylos, the manzanitas and bearberries. Common names include red fruit bearberry, alpine bearberry, arctic bearberry, red manzanita, and ravenberry. It is native to Eurasia and northern North America from Alaska through most of Canada to Greenland. There is also one population in the contiguous United States, located in the Absaroka Mountains of Wyoming.

<i>Geocaulon</i> Species of flowering plant in the mistletoe family Santalaceae

<i>Epinotia nemorivaga</i> Species of moth

Epinotia nemorivaga, the bearberry bell, is a species of moth in the family Tortricidae. It is found in Europe and Asia.

Spruce broom rust or yellow witches' broom rust is a fungal plant disease caused by the basidiomycete fungus known as Chrysomyxa arctostaphyli. It occurs exclusively in North America, with the most concentrated outbreaks occurring in northern Arizona and southern Colorado on blue and Engelmann spruce, as well as in Alaska on black and white spruce. This disease alternates its life cycle between two hosts, with the spruce serving as the primary host and bearberry serving as the secondary or alternate host. The name for the disease comes from the distinctive “witches broom”, commonly yellow in color, which forms on the spruce after young needles have been infected. Management must be carried out through physical or mechanical methods, such as the pruning of brooms or the removal of the secondary host from the area, because no chemical control measures have yet been determined to be economically effective. Generally, spruce broom rust is seen as a mostly cosmetic issue, and it is very rarely the direct cause of tree death; however, research has shown a reduction in overall productivity and health of infected trees, making it an important issue for logging and timber companies.
