Arctous
Definition
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.
