--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, forming loose clumps, from elongate rhizomes. <b>Stems</b> erect or straggling, branched, square, 10–35 cm, glabrous but angles minutely papillate-scabrid. <b>Leaves</b> sessile; blade green to yellowish green, never glaucous, linear to very narrowly elliptic, widest at or beyond middle, 0.8–4 cm × 1–3 mm, not coriaceous, base attenuate, apex acuminate to acute, glabrous to sparingly ciliate at base, margins minutely papillate-scabrid; proximal leaves shorter and wider. <b>Inflorescences</b> terminal, widely divaricate, 2–many-flowered cymes; bracts lanceolate, 1–5 mm, scarious, apex acuminate. <b>Pedicels</b> straight or somewhat arcuate, commonly 3–30 mm, glabrous or scabrous. <b>Flowers</b> 5–9 mm diam.; sepals 5, obscurely 3-veined, ovate-elliptic, 2–4 mm, margins scarious, apex acute, glabrous; petals 5, 2–3.5 mm, ± equaling sepals; stamens 5–10; styles 3, ascending, ca. 1 mm. <b>Capsules</b> blackish purple or straw colored, ovoid-conic, 3–6 mm, much longer than sepals, opening by 6 valves; carpophore absent. <b>Seeds</b> brown, broadly reniform, 0.7–0.8 mm diam., slightly rugose. <b>2n</b> = 26.</span><!--

|discussion=<p><i>Stellaria longifolia</i> often is confused with forms of <i>S. longipes</i> but differs in having leaves that are widest at or above the middle and in having the angles of the stem and/or the leaf margins minutely papillate-scabrid. The capsules can be either straw colored or black. Plants with black capsules have been named var. atrata.</p><!--
--><p>Hybrids with <i>Stellaria borealis </i>subsp.<i> borealis</i> often occur; see note under that species.</p>
