General:
Low, matted shrub; stems ascending, 5-40 cm tall, finely hairy and glandular, becoming glabrous.
Leaves:
Alternate, evergreen, spreading-ascending, linear or linear-oblong, 3-15 mm long, 1-2 mm wide, blunt to nearly pointed, deeply grooved beneath, margins appearing to be rolled under, glabrous except margins with small, fine, glandular teeth.
Flowers:
Several to many, in terminal clusters, fragrant, nodding; flower stalks about 2 cm long, finely glandular-hairy; corollas deep pinkish-rose, bell-shaped, 5-9 mm long, glabrous externally, the lobes curved back; calyces reddish, 2-3 mm long, lobes lance egg-shaped, blunt, glabrous except for finely fringed margins; stamens 10, included; filaments glabrous, anthers reddish.
Fruits:
Capsules, nearly globe-shaped, 2.5-3.5 mm long, 3-4 mm wide, glandular-hairy.
Notes:
The hybrid between P. empetriformis and P. glanduliflora is known as P. x intermedia (Hook.) Rydb., and is quite common where the two occur together. The hybrids generally have white to pale rose corollas, and other intermediate characters.

Ecological Indicator Information

A shade-intolerant, sub­alpine to alpine, oxylophytic, Asian and West­ern North American evergreen shrub; distributed equally in the Pacific and Cordilleran regions. Species occurs on moderately dry to fresh, nitrogen-poor soils in alpine tundra and subalpine boreal climates. Common, frequently dominant, in high-elevation, parkland forests and heath communities on water-shedding sites which are often affected by seepage from late-melting snowbanks. Characteristic of alpine communities.
