Subshrubs, creeping, not mat-forming, rhizomatous or stoloniferous; adventitious-roots absent. Stems decumbent, branches ascending, 5–20 cm, lanate, glabrescent. Leaf-blades (pale green abaxially, bright green, glaucous adaxially), obovate to oval or orbiculate, 1.5–4.5 cm, base cuneate to rounded, margins serrate (teeth bristle-tipped), (slightly revolute), apex acute to rounded or obtuse, rarely mucronate, surfaces sparsely hairy (hairs unbranched). Inflorescences axillary, solitary flowers or with 2–3 nodding flowers per node; bracts reddish, cordate, distinctly concave, 1–2 mm, not exceeding sepals, ciliate marginally. Pedicels pinkish, 1–3 mm, lanate; bracteoles absent. Flowers: sepals 5, connate 1/2 to nearly their entire lengths, white, cordate, 2.5–3.5 mm, ciliate marginally; petals 5, connate nearly their entire lengths, white, 8–10 mm, adaxial surface lanate-hairy, corolla urceolate, lobes 1 mm; filaments (pinkish), slightly widened proximally, lanate-tomentose; anthers with 2 apical awns (awns not bifurcating), dehiscent by subterminal pores proximal to awns. Fruits bright red to reddish violet, 6–9 mm wide. 2n = 44, 88.


Phenology: Flowering Jun–Sep; fruiting Sep–Jan.
Habitat: Mixed woodlands, mesic forests, dry, acidic woodlands, powerline rights-of-way, roadbanks, old pastures, coniferous woodlands, maritime heathlands, montane heath balds, bogs and fens, usually in acidic and/or sandy soils
Elevation: 0-1500 m
