General: Evergreen, creeping, semiwoody herb or subshrub; stems long, slender, weakly rooting, thinly hairy and often also glandular, producing numerous short (less than 10 cm tall), more or less erect, leafy stems or branchlets with 2-4 pairs of leaves.
Leaves: Opposite, simple, short-stalked, egg-shaped to nearly circular, with a few shallow teeth along the upper half, 7-25 mm long, 5-15 mm wide, leathery, dark green above, paler below, glabrous or the stalks and margins of the leaf bases often fringed with long hairs.
Flowers: Inflorescence of nodding pairs of flowers on slender, erect, Y-shaped stalks that terminate the leafy branchlets; base of flowers cradled by two tiny bracts; corollas slenderly funnel-shaped, 9-16 mm long, pink to whitish, flaring above to 5 lobes, hairy in the throat; styles about as long as corollas, with a tiny knoblike stigma; stamens 4.
Fruits: Dry 1-seeded achenes (nutlets), flanked by a pair of tiny glandular bracts.
Notes: Two subspecies occur in BC:
1. Corollas 9-11 mm long, narrowly bell-shaped, flaring from within the calyces, tubes very short or sometimes absent................... ssp. borealis
1. Corollas 10-16 mm long, funnel-shaped, tubes about equalling or surpassing the calyces...................ssp. longiflora (Torr.) Hult.
Mesic forests in the lowland and montane zones; ssp. longiflora common throughout BC; ssp. borealis infrequent in extreme NW BC; ssp. borealis - circumboreal, N to AK and YT, ssp. longiflora - N to AK, YT and NT, E to NF and S to IN, NM and CA.
A shade-tolerant/intolerant, submontane to subalpine, circumpolar evergreen shrub (transcontinental in North America). Occurs predominantly on moderately dry to fresh soils within boreal, cool temperate, and cool mesothermal climates. Scattered to plentiful in mossy understories in coniferous forests on watershedding sites: on moist and wet sites it inhabits topographic prominences, on nutrient-rich sites it is restricted to decaying coniferous wood; persists on undisturbed cutover sites. Commonly associated with Cornus canadensis, Goodyera oblongifolia, Hylocomium splendens, Kinbergia oregana, and Vaccium parvifolium. Characteristic of Moder and acidic Moder humus forms.
