--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual. <b>Taproots</b> filiform to somewhat thickened. <b>Stems</b> erect to widely spreading, green or purple, 4–30 cm, stipitate-glandular distally, internodes of all stems 1–5 times as long as leaves. <b>Leaves</b> sometimes overlapping proximally, ± evenly spaced, connate proximally, with loose, scarious sheath 0.3–0.7 mm; blade straight to variously curved or coiled, green or purple, concave, 1–3 veined, linear, 5–40 × 0.2–0.4 mm, flexuous, margins not thickened, often scarious, sometimes ciliate or stipitate-glandular, apex green to purple, acute, navicular, dull, glabrous to stipitate-glandular; axillary leaves present proximally. <b>Inflorescences</b> 7–15+-flowered, open cymes; bracts subulate, scarious. <b>Pedicels</b> 0.2–4 cm, stipitate-glandular. <b>Flowers</b>: hypanthium disc-shaped; sepals 1(–3)-veined, midvein often more prominent than lateral veins, ± ovate (herbaceous portion lanceolate to oblong-lanceolate to narrowly ovate), 2.5–3.7 mm, not enlarging in fruit, apex often purple, obtuse to acute, not hooded, stipitate-glandular at least proximally; petals ovate, (1–)1.7–2.1 times as long as sepals, apex broadly rounded, entire or irregularly dentate. <b>Capsules</b> on stipe 0.3–0.5 mm, broadly ovoid, 4 mm, longer than sepals. <b>Seeds</b> reddish brown, winged, orbiculate with radicle not prolonged, compressed, 1.3–2 mm, tuberculate; tubercles low, elongate.</span><!--

|discussion=<p>The winglike margins on the seeds of <i>Minuartia douglasii</i> are unique among North American members of the genus; <i>M. howellii</i> and <i>M. tenella</i>, the other members of sect. Greniera (Gay) Mattfeld, do not share this feature.</p><!--
--><p>Plants with petal apices usually emarginate rather than entire and obtuse and often shorter than in typical plants have been recognized by some as var. emarginata.</p>
