--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>5–50 cm. <b>Stems</b> erect to spreading or recurved, green when young, soon becoming tan to brown, then nearly black when older, highly branched, twigs glabrous, glandular, usually resinous. <b>Leaves</b> ascending to spreading; blades usually elliptic to oblanceolate, occasionally spatulate, 10–15 × 0.5–1.5 mm, mostly adaxially sulcate, margins entire, midnerves usually obscure to weakly evident, apices acute, apiculate, faces glandular, sometimes irregularly gland-dotted (in shallow pits), resinous; axillary fascicles present, persistent. <b>Heads</b> in congested, cymiform arrays (0.5–2.5 cm wide). <b>Peduncles</b> 0.2–5 mm (mostly ebracteate, glabrous). <b>Involucres</b> obconic, 5.5–7.5 × 2.5–4 mm. <b>Phyllaries</b> 22–30 in 4–5 series, mostly tan, lanceolate to elliptic, 2–6.5 × 0.5–1.2 mm, strongly unequal, outer sometimes herbaceous or herbaceous-tipped (body apices obtuse or truncate to retuse, appendages erect), midnerves not evident or slightly raised, slightly expanded subapically, (mostly margins narrowly membranous, entire) apices acute to acuminate or attenuate, mid often aristate to cuspidate, abaxial faces glabrous, resinous. <b>Ray</b> florets 1–7; laminae elliptic, 3–4 × 0.8–1.3 mm. <b>Disc</b> florets 4–8; corollas 4.5–6.5 mm. <b>Cypselae</b> tan, narrowly oblanceoloid, 4–5.5 mm, glabrous or densely sericeous; pappi tan, 4–5.5 mm. <b>2n</b> = 18.</span><!--
