--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> annual, 5–60 cm, glabrous. <b>Stems</b> ± spreading or ascending, or branches from base prostrate. <b>Leaves</b>: blade linear to linear-oblanceolate, 8–20 × 0.7–2.3 mm. <b>Inflorescences</b>: open panicles or racemes. <b>Pedicels</b> 8–25 mm. <b>Flowers</b> homostylous; sepals ovate, 3–5 mm, margins glabrous, apex acute; petals usually blue, rarely white, obovate, 5–14 mm; stamens 3–5 mm; anthers 0.4–1.3 mm; staminodia present; styles distinct, 1–3 mm; stigmas capitate. <b>Capsules</b> broadly ovate to subglobose, 4–6 mm diam., apex obtuse, segments persistent on plant, margins ciliate. <b>Seeds</b> 3–5 × 1.2–1.6 mm. <b>2n</b> = 18.</span><!--

|discussion=<p>In a study of pollination in <i>Linum pratense</i>, G. E. Uno (1984) observed that petals dropped soon after anthesis and the persistent sepals quickly moved inward, pressing the dehiscing anthers against the receptive stigmas. Small bees and flies were seen to visit flowers even after the petals fell. Uno noted sepals closing in both <i>L. lewisii</i> and <i>L. rigidum</i>, but in these species the stamens tend to be somewhat shorter than the styles so self-pollination was less likely.</p><!--
--><p>C. M. Rogers (1984) wrote that some plants of <i>Linum pratense</i> intergrade with <i>L. lewisii</i> in areas where their ranges overlap; however, in most of its range, <i>L. pratense</i> is the only blue-flowered <i>Linum</i>, and can be distinguished from the occasional plant of <i>L. bienne</i> or <i>L. usitatissimum</i> by its lack of cilia on the inner sepals and its capitate stigmas.</p>
