--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> annual; taproot slender. <b>Stems</b> arising directly from the root, erect to spreading, solid, not fistulose or disarticulating into ringlike segments, sparsely glandular-pubescent. <b>Leaves</b> usually quickly deciduous, basal, rosulate; petiole absent; blade spatulate to obovate, margins entire. <b>Inflorescences</b> terminal, cymose, uniparous due to suppression of secondaries; branches dichotomous, not brittle or disarticulating into segments, round, sparsely glandular-pubescent; bracts 3(–5), positioned to side of node or perfoliate and completely but unequally surrounding node, connate nearly completely, triangular to ovate or oblong, awned, sparsely glandular-pubescent. <b>Peduncles</b> absent. <b>Involucres</b> 1–3 per node, tubular, cylindric, (2–)3–4-angled, slightly ventricose on the angles in some; teeth (2–)3–4, awn-tipped. <b>Flowers</b> 1(–2) per involucre; perianth white to pink, campanulate when open, cylindric when closed, pubescent abaxially; tepals 6, connate ca. 1/3 their length, monomorphic, entire or erose to fimbriate apically; stamens 6–9; filaments free, glabrous; anthers pink to red, oblong. <b>Achenes</b> mostly included, brown to black, not winged, globose-lenticular, glabrous. <b>Seeds</b>: embryo straight. <b>x</b> = 19.</span><!--
