Plants annual or biennial, highly variable in size from inconspicuous to moderately robust, not mat-forming. Leaves in single rosette; petiole obscure to absent; blade oblanceolate to spatulate, 5-30 × 3-10 mm, base obscurely narrowing to stem, margins often ciliate, surfaces glabrescent to hairy, hairs straight. Scapes 1-5(-10), 1-10(-15) cm, glabrescent, puberulent, or, sometimes, stipitate-glandular. Inflorescences 5-20-flowered; involucral bracts narrowly lanceolate to linear-lanceolate, relatively narrow. Pedicels erect to arcuate, slender, unequal, 0.3-6 cm. Flowers: calyx narrowly campanulate, with prominent ridges, 3-5 mm, lobes erect, broadly lanceolate, apex acute; corolla tube equaling or shorter than calyx, limb to ca. 3 mm diam. Capsules ± equaling calyx, 3-5 mm. 2n = 20. Flowering spring-early fall. Open areas with sandy, gravelly soil in grassland, shrub, forest, and tundra communities; 0-3500 m; Greenland; Alta., B.C., Man., Nfld. and Labr.

Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Delicate upright, annual 1-30 cm tall, with a clustered stem. Leaves: Basal, with blades 5-20 mm long, sessile, blades lanceolate, glabrous to pubescent. Flowers: Inflorescence with lanceolate to linear-lanceolate bracts; white or pink flowers; calyx 2.7-4.7 mm long, glabrous or with occasional white or reddish-brown hairs, the lobes shorter than or barely equaling tube; corolla longer than or equal to the calyx. Fruits: Valvate capsule. Ecology: Found on gravelly stream beds, in moist ground of springs or meadows, mountain parks, or open coniferous forests from 5,000-12,000 ft (1524-3658 m); flowers April-September. Notes: Told apart from A. occidentalis by the lanceolate to linear-lanceolate involucral bracts, and the corolla being longer than the calyx. The former is also found at all the lower elevation from 1000-8000 ft (305-2438 m). Ethnobotany: Taken for internal pain, as a life medicine, for venereal disease, as protection from witches, and sometimes steeped to make a beverage. Etymology: Androsace from Green name for sea-plant from Greek andros, a man, male and sakos, a shield, while septentrionalis means or or pertaining to the north.
