--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>3–50[–70] cm. <b>Stems</b> usually 1, erect; branches leafy between proximal forks, remaining grayish to whitish, lanuginose to sericeous. <b>Leaves</b> oblanceolate to lanceolate, largest 14–20(–40) × 3–4(–5) mm, pliant; longest capitular leaves 0.8–1.5(–2) times head heights, acute. <b>Heads</b> mostly in glomerules of 2–10(–13) in racemiform to paniculiform arrays, broadly pyriform to ± cylindric, largest 4–6 × 3.5–5 mm. <b>Phyllaries</b> 0, vestigial, or 1–4, unequal, ± like paleae. <b>Receptacles</b> ± fungiform, 0.4–0.7 mm, heights 0.4–0.5 times diams. <b>Pistillate</b> paleae (except innermost) 2–4(–6) in 1(–2) series, spirally ranked, loosely saccate, incurved 20–60°, scarcely gibbous, not galeate, longest 3.3–4.5 mm, distal 5–10% of lengths glabrous abaxially; bodies ± cartilaginous, ± terete; wings obscured by indument. <b>Innermost</b> paleae ± 8, spreading in 2 series, pistillate. <b>Pistillate</b> florets: outer 2–4(–6) epappose, inner 15–20 pappose. <b>Bisexual</b> florets 3–4; corollas 2.3–3 mm, lobes mostly 4, reddish to purplish. <b>Cypselae</b>: outer nearly straight, ± erect, compressed, 0.9–1.1 mm; inner papillate; pappi of 17–23 bristles falling in complete or partial rings, 2.5–3.5 mm. <b>2n</b> = 28 (Caucasus, Finland, Germany, Slovakia).</span><!--

|discussion=<p><i>Logfia arvensis</i> appears to be basal or nearly so in <i>Logfia</i> and Filagininae (J. D. Morefield 1992); only 2–4 epappose florets are present in most heads. Reports of <i>L. arvensis</i> from Ontario and New York have not been confirmed by me. A report from the Desert National Wildlife Range in southern <i>Nevada</i> (T. L. Ackerman et al. 2003) was likely based on specimens of <i>L. filaginoides</i>. The earliest specimen confirmed from the flora area was from Bonner County, Idaho, in 1934. The label on one nineteenth-century specimen (mixed with <i>Diaperia verna</i>) identifying it as coming from Dallas, Texas, is probably in error; no other collections of <i>L. arvensis</i> are known from in or near Texas.</p>
