Inflorescences 1-5-flowered; bracts 1-4 mm, margins broadly scarious. Pedicels ascending to erect, sometimes divergent in fruit, 2-15 mm. Flowers: sepals 5, midrib ± keeled, ovate, herbaceous portion lanceolate, (2.8-)3-6 mm, apex acute to acuminate; petals 5, 2-6 mm, 3/ 1/ 2 times as long as sepals. Capsules ovoid, 5 mm, ± equaling sepals. Seeds ovoid, 1.5-2.2 mm, tuberculate; tubercles minute, low, rounded. 2n = 48.

Flowering late spring-summer. Moist, shaded slopes, rocky ridges, ultramafic outcrops and summits, shores; 200-3400 m.; B.C., Man., Nfld. and Labr. (Labr.), N.W.T., Ont., Que., Sask.; Calif., Colo., Conn., Idaho, Mass., Mich., Mont., N.Mex., Ore., Utah, Vt., Wash., Wis.; Asia.
