Aerial stems erect. Leaves mainly basal and distributed along the stems (a few cauline leaves present along taller stems); alternate; dying annually and non-persistent (blades), or marcescent (petioles). Stipules present; 0.8–15 mm long; 1.5–5(–8) mm wide; sheathing; brown, or white, or colourless; glabrous; apex truncate. Petioles 4–45 mm long; glabrous (usually), or hairy (sometimes short-hairy margins and veins); pubescent (when hairs present). Petiole hairs shorter than the diameter of the petiole; spreading, or erect (when present); curved, or wavy (when present). Leaf blade bases rounded (basal leaves), or attenuate (stem leaves). Blades 4–50(–80) mm long, 3–10 mm wide, appressed to the stem or spreading, oblong or elliptic, flat, appearing single-veined. Blade adaxial surface highly glossy, glabrous. Blade abaxial surface hairy, hairs tomentose, hairs sparse, hairs white and rust-coloured, hairs wavy, hairs spreading. Blade margins slightly revolute. Blade apices acute.

Pedicels absent. Flowers per inflorescence 10–80; small; bisexual (often sterile in arctic plants). Sepals conventional (tepals); 5; free; 0.7–1.5 mm long; 1.5–3 mm wide; pink, or white; petaloid; accrescent (slightly). Calyx glabrous. Petals absent. Stamens 3–5; stamen filaments glabrous. Anthers 0.3–0.4 mm long. Ovary superior; carpels 3; syncarpous. Ovaries glabrous. Styles 2–3 (fused at the base and branching into 2–3 long branches with stigmatic tips); free; 0.8–1.8 mm long. Stigmas per ovary 2, or 3 (per flower). Placentation basal. Ovules per ovary 1. Fruit sessile; with calyx persisting; dry; an achene; ovoid; brown; 1.7–3 mm long; 1–1.8 mm wide; surface appearing veinless; not distinctly flattened; indehiscent. Achenes trigonous.

Indigenous knowledge. An Inuit name for this species is sapangaralannguat and means "imitation small beads". The starchy rhizome of this species is called uqpigait, and can be eaten raw, but since it is slightly astringent, it is better eaten cooked (Ootoova et al. 2001). Eva Aariak (personal communication, 2006) claimed that in her experience the "nut" was always eaten raw. In Alaska, the roots are eaten raw in summer (Lantis 1959).
The rootstocks, although slightly astringent, are rich in starch and have a sweet, nutty flavour (Porsild 1953).
Called "Inuit nuts" in Iqaluit, they have a taste like almonds (Sherry Sadler, personal communication, 2003). Other names for this plant are turlait, tuqtait, and inuit qaqquangangit. The Inuit eat the leaves and bulbils as well (Mallory and Aiken 2004).
Ecology and habitat. Substrates: hummocks, around the margins of ponds, along streams, river terraces, lakeshores, tundra, slopes, ridges, cliffs; dry, moderately well-drained areas; rocks, gravel, sand, till.

General notes. This species is treated under the name Bistorta in several references such as Flora of North America (Freeman and Hinds 2005), Flora Europaea, and Flora Nordica.
Russell (1940) performed ecological studies on arctic vegetation and found that Oxyria digyna and Persicaria vivipara (Polygonum viviparum) showed adequate carbon assimilation for increased growth, but that low temperature and low nitrogen supply curbed the growth rate. Savile (1972) suggested that these restrictions halted growth soon enough to ensure adequate seed production in the short summer.
"This bistort often grows in areas of high soil fertility, near animal dens, bird nesting sites, or human habitations. The pecan-shaped rhizomes have long been used by the Inuit, and the leaves and bulbils were often eaten. The bulbils are also sought by ptarmigan and small seed-eating birds" (Burt 2000, p. 60).
Kellman (1882) stated that according to people in Chukotka, the rhizomes of this plant must be collected immediately after the snow leaves the ground and before the first leaves appear. Only the rhizome, which is the size on an unshelled peanut, is used. To find and collect it in spring is no easy task, but Kellman reported that the people he observed had surprisingly good results. Elven (personal communication, 2005) noted that it is easy to find, as the withered leaves remain over winter.
