Plants rhizomatous, 1.2–2.7 (–3.3) dm. Leaves: petiole 4–20 mm, channeled adaxially, glabrous; blade dull and light green abaxially, shiny and green adaxially, (10–) 20–47 (–58) × 7–28 (–35) mm, base rounded to acute, apex rounded to acute. Inflorescences (2–) 3–29-flowered; peduncle 10–20 (–25) cm, peduncular bracts absent or 2–7, subulate to narrowly or broadly lanceolate, 3–9 × 1–2 mm, membranous, margins entire or erose-denticulate; inflorescence bracts subulate to lanceolate-ovate or narrowly ovate, ca. as long as pedicels they subtend, 4–9 × 0.4–1.8 mm, herbaceous. Pedicels (1–) 3–7 (–9) mm. Flowers: calyx lobes appressed or spreading in fruit, entirely green or margins hyaline to white or pinkish, 0.5–1.5 × 0.5–1.3 mm, margins erose-denticulate, sometimes obscurely so, apex rounded to obtuse; petals broadly ovate, 4.5–6 × 3–4 mm, margins erose-denticulate or irregularly toothed; stamens 4–8 mm; filament base 0.1–0.3 mm wide; anthers 1.2–1.8 mm, thecae tan or light-brown, pores 0.2–0.5 × 0.2–0.4 mm; ovary smooth; style 3–5 (–7) mm; stigma 1.4–2 mm wide.

Discussion

Plants in open, alpine and arctic habitats often have leaf blades orbiculate to orbiculate-ovate, 10–20 mm, apices obtuse, anthers ca. 1 mm, and styles 3–4.5 mm, and have been called Orthilia secunda subsp. obtusata. E. Haber (1972) concluded that these characters vary too freely among populations to warrant distinction.

The Southern Carrier of British Columbia made a decoction from the roots, which they used as an eyewash (D. E. Moerman 1998).
