--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, mat-forming. <b>Taproots</b> thickened, woody; crown, many-branched, woody; rhizomes and trailing stems to 60 cm. <b>Stems</b> ascending to erect, ± green, 2–20 cm, densely glandular-hairy throughout, internodes of flowering stems 0.2–2 times as long as leaves. <b>Leaves</b> tightly appressed to spreading, ± evenly spaced, connate proximally, with ± loose, scarious sheath 0.1–0.7 mm; blade straight to recurved, ± green, flat, prominently 1-veined abaxially, broadly lanceolate to linear, 5–20 × 0.5–1.5 mm, ± rigid, margins rounded, scarious in proximal 1/3–1/4, apex green to purple, acute to acuminate or spinescent, navicular with small mucro or spinescent, dull, stipitate-glandular; axillary leaves present proximally to throughout. <b>Inflorescences</b> (3–)6–30-flowered, open cymes; bracts lanceolate to subulate, usually scarious. <b>Pedicels</b> 0.2–2 cm, stipitate-glandular. <b>Flowers</b>: hypanthium disc-shaped; sepals 1–3-veined, narrowly lanceolate to lanceolate or ovate (herbaceous portion narrowly lanceolate to lanceolate or ovate), 3–6(–7) mm, not enlarging in fruit, apex often purple, acute to acuminate or spinescent, not hooded, stipitate-glandular; petals obovate, 0.5–1.6 times as long as sepals, apex rounded, entire. <b>Capsules</b> on stipe ca. 0.1–0.2 mm, ovoid, 5 mm, usually shorter than sepals. <b>Seeds</b> reddish brown to dark brown, oblong-elliptic with hilar notch on 1 end, 1.5–2.7 mm, tuberculate; tubercles low-rounded.</span><!--

|discussion=<p>Varieties 4 (4 in the flora).</p><!--
--><p><i>Minuartia nuttallii</i>, <i>M. decumbens</i>, <i>M. rosei</i>, and <i>M. stolonifera</i> form a complex that, together with the eastern species <i>M. caroliniana</i> and <i>M. michauxii</i>, comprise sect. Sclerophylla Mattfeld. The four western species all have capsules that contain one to three(?) large (1.5–2.8 mm) seeds; unfortunately, these plants appear to be collected only rarely in fruit.</p><!--
--><p><i>Minuartia nuttallii</i> includes four varieties, which can, for the most part, be easily recognized. There is some overlap between <i></i>var.<i> gracilis</i> and <i></i>var.<i> fragilis</i> in western <i>Nevada</i> and southeastern Oregon, where some plants exhibit prominently arcuate-spreading leaves (as in <i></i>var.<i> fragilis</i>) and weakly veined sepals (as in <i></i>var.<i> gracilis</i>).</p>
