All the US and some of the Canadian material belongs to Empetrum eamesii subsp. atropurpureum (Fernald & Wiegand) D.Löve which has been regarded as a separate species by some authorities[5] but not others.[3][4]

Empetrum eamesii is a low-lying, evergreen 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.
