The '''Polar Willow''' (''Salix polaris'') is a species of [[willow]] with a [[circumpolar]] distribution in the high [[arctic]] [[tundra]], extending north to the limits of land, and south of the arctic in the [[mountain]]s of [[Norway]] and [[British Columbia]], [[Canada]].
One of the smallest willows in the world, it is a prostrate, creeping dwarf [[shrub]], only 2-3 cm high, and has underground branches or runners in the uppermost soil layers. The [[leaf|leaves]] are rounded-ovate, dark green and have entire margins. It is [[plant sexuality|dioecious]], with separate female and male plants. The [[flower]]s are grouped in short [[catkin]]s each bearing only a few flowers. The [[fruit]] is a brownish and hairy [[capsule (fruit)|capsule]]. The long runners with freely-rooting stems creep in mats of [[moss]]es and [[lichen]]s, which keeps them together and protects them from the wind. It grows as well in open [[gravel]] as closed vegetation.
