#arctous

• Arctous — A taxonomic genus of perennial plants in the family Ericaceae, comprising a small number of dwarf, prostrate, deciduous shrub species distributed throughout subarctic, alpine, and circumboreal regions of the Northern Hemisphere. Structurally, the genus Arctous was evolutionarily separated from Arctostaphylos by its thin, serrated leaves that fall in autumn after turning a brilliant bright red, and by its juicy, non-stony drupe fruits.
• Alpine bearberry — The scientific name for the alpine bearberry, a deciduous dwarf shrub in the family Ericaceae, characteristic of arctic tundra and high-altitude alpine meadows. In a structural and biological sense, the Arctous alpinus species stands out for its prostrate branches forming dense ground carpets, serrated leaves turning intense purplish-red before dropping, small, greenish-white flowers, and spherical berries that become glossy-black at maturity, representing an essential trophic resource for migratory birds.
• Arctous ruber — The official binary name or taxonomic synonym for a dwarf shrub species in the Ericaceae family, popularly known as the red bearberry (or Arctostaphylos rubra), structurally adapted to extreme alpine and arctic climates. The plant features deciduous leaves that turn bright red in autumn, small urceolate flowers, and spherical, juicy, dark-red berries that serve as an important food source for mountain wildlife.
