Flowers: In terminal 1- to 12-flowered clusters; flower stalks 1-4 cm long, usually glabrous; corollas deep pinkish-rose, saucer-shaped, 1-2 cm wide; calyces deeply 5-lobed, lobes egg-shaped, 2-3 mm long, glabrous or occasionally sparsely and minutely fringed; stamens 10, held in sacs on petals until full bloom, densely hairy just above the base, otherwise glabrous.

Notes: Two subspecies are recognized in BC:
1. Leaves oval to broadly elliptic, usually less than 2 cm long, and less than 2 times as long as wide; calyces less than 7 mm wide; plants occurring E of the Coast-Cascades Range in BC and usually at high elevations..............ssp. microphylla
1. Leaves lance-shaped, usually 2.5 cm long or longer, and 2.5-4 times as long as wide; calyces more than 7 mm wide; plants of coastal BC and intermittently inland, usuallyat low to moderate elevations..................ssp. occidentalis (Small) Taylor & MacBryde
