--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual, slender, finely glandular-pubescent (often perennial and tomentose in <i></i></i>var.<i><i> obtectum</i>), with slender taproot. <b>Stems</b> erect, simple or branched at or near base, sometimes with straggling, nonflowering basal shoots, 10–50 cm, softly pubescent, often with a few long, flexuous, woolly hairs at proximal nodes, glandular and somewhat viscid distally; small axillary tufts of leaves usually absent. <b>Leaves</b> marcescent or not, sessile; blade oblanceolate to spatulate in proximal leaves, becoming lanceolate to linear-lanceolate in distal leaves, occasionally elliptic, 10–60 × 3–15 mm, apex acuminate to acute, softly pubescent and glandular, sometimes tomentose. <b>Inflorescences</b> rather open, 3–21(–40)-flowered cymes, ultimately widely branched; bracts herbaceous, lanceolate, glandular-pubescent. <b>Pedicels</b> ascending, sharply deflexed at apex in fruit, 5–20(–35) mm, usually 1–3 times as long as sepals in flower, elongating to 5 times as long as sepals in fruit, longer than capsules, glandular-pubescent and viscid. <b>Flowers</b>: sepals ovate-lanceolate, 4–6 mm, outer sepals herbaceous or with narrow margins, inner with margins ca. as wide as herbaceous center, apex broadly acute to obtuse, glandular-puberulent, hairs shorter than sepal tips; petals oblanceolate, sometimes absent, 3–6(–8) mm, shorter to 1.5 times longer than sepals, apex 2-fid; stamens 10; styles 5. <b>Capsules</b> cylindric, curved, (9–)10–12(–13) mm, 2–3 times as long as sepals; teeth 10, erect, margins convolute. <b>Seeds</b> golden brown, 0.5–0.8 mm diam., shallowly tuberculate; testa not inflated. <b>2n</b> = 34, 36.</span><!--
