--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>grayish green to silvery, 3–15 cm, sericeous to lanuginose. <b>Stems</b> mostly 2–10; branches proximal and distal (distal opposite or, sometimes, appearing alternate when unequal), rarely none. <b>Leaves</b>: largest 7–15 × 2–4 mm; capitular leaves subtending glomerules, also visible between and surpassing heads. <b>Heads</b> in strictly dichasiform or pseudo-polytomous arrays (sometimes appearing monochasiiform), cylindric to ± ellipsoid, 3.5–4.5 mm, heights 2–3 times diams. <b>Receptacles</b> broadly or narrowly conic, 0.4–0.6 mm or ± 0.9–1.1 mm, heights 0.5–0.7 or 2–2.4 times diams. <b>Pistillate</b> paleae imbricate, longest 2.5–4 mm. <b>Staminate</b> paleae ± 3, apices erect to somewhat spreading, ± plane. <b>Functionally</b> staminate florets 2–4; ovaries partly developed, 0.4–0.6 mm; corollas hidden in heads, actinomorphic, 1.4–2 mm, glabrous, lobes equal. <b>Bisexual</b> florets 0. <b>Cypselae</b> ± angular, obcompressed, mostly 0.9–1.2 mm.</span><!--

--><p>Intermediates between the two varieties of <i>Diaperia prolifera</i> occur where their ranges meet in central Texas and central Oklahoma. The strictly dichasiform or pseudo-polytomous branching pattern of <i>D. prolifera</i> is distinctive and diagnostic within the genus. Specimens of <i>D. prolifera</i> from introductions around a wool mill in South Carolina (G. L. Nesom 2004c, as Evax prolifera) are as yet undetermined to variety and are not included in the distributions below.</p>
