--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, sometimes mat-forming, green. <b>Taproots</b> filiform to somewhat thickened. <b>Stems</b> erect to ascending, green, 4–30 cm, glabrous, internodes of flowering stems 1–10 times as long as leaves. <b>Leaves</b> overlapping or crowded proximally, variably spaced distally, connate proximally, with tight, scarious to herbaceous sheath 0.2–0.5 mm; blade straight to slightly outwardly curved, green, flat, 1-veined, occasionally 3-veined abaxially, linear to subulate, 4–15 × 0.5–2 mm, flexuous, margins not thickened, scarious, smooth, apex green or purple, mostly rounded, slightly navicular, shiny, glabrous; axillary leaves present among proximal cauline leaves. <b>Inflorescences</b> 7–15-flowered (rarely fewer), open cymes; bracts subulate, herbaceous. <b>Pedicels</b> 0.3–2.5 cm, glabrous. <b>Flowers</b>: hypanthium disc-shaped; sepals prominently 3-veined, ovate to broadly lanceolate (herbaceous portion ovate to broadly lanceolate), 2.5–3.2 mm, to 4 mm in fruit, apex green to purple, acute to apiculate, not hooded, glabrous; petals lancolate to spatulate, 0.5–0.8 times as long as sepals, apex rounded, entire, or petals absent. <b>Capsules</b> on stipe ca. 0.2 mm, ovoid, 3.5–4.5 mm, longer than sepals. <b>Seeds</b> dark brown to black, suborbiculate with radicle prolonged into tiny beak, 0.5–0.6 mm, tuberculate; tubercles low, rounded, somewhat elongate. <b>2n</b> = 30, 60.</span><!--

|discussion=<p>Although sometimes included in <i>Minuartia michauxii</i> [e.g., H. J. Scoggan’s (1978–1979, part 3) treatment of <i>Arenaria</i> stricta], <i>M. dawsonensis</i> is more closely related to the circumpolar <i>M. stricta</i>.</p><!--
--><p><i>Minuartia</i> litorea, known from Quebec and Ontario, may deserve recognition. An unpublished chromosome count suggests that it is a recent allopolyploid derived from <i>M. dawsonensis</i> and <i>M. rubella</i> (L. Brouillet, pers. comm.).</p>
