--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> perennials, or subshrubs [shrubs], 10–90+ cm. <b>Stems</b> erect, virgately to divaricately branched. <b>Leaves</b> cauline; proximally opposite (first 2–10+ pairs in early growth, Feb–Apr), otherwise alternate; petiolate; blades (3-nerved) lance-linear to lanceolate (proximal) or ± deltate or ovate to elliptic or lanceolate (distal), margins entire or toothed, faces sericeous to strigillose, sometimes with coarser, erect hairs, usually gland-dotted as well. <b>Heads</b> disciform or discoid (then functionally staminate), in (mostly ebracteate) racemiform to paniculiform arrays [borne singly or loosely aggregated in 2s or 3s]. <b>Involucres</b> ± cup-shaped to saucer-shaped, 3–5+ mm diam. <b>Phyllaries</b> persistent (outer) or tardily falling, distinct, outer (4–)5(–7) in 1 series, ± herbaceous, inner 0–4 (each subtending a pistillate floret), scarious to membranous (accrescent, ultimately ovate to elliptic in fruit). <b>Receptacles</b> convex; paleae cuneiform to linear, membranous, ± villous to hispid distally, sometimes wanting. <b>Pistillate</b> florets (0–)1–4; corollas 0. <b>Functionally</b> staminate florets 5–15+; corollas whitish, funnelform, lobes 5, erect, reflexed, or incurved (anthers distinct or weakly coherent). <b>Cypselae</b> strongly obcompressed, often slightly cucullate, ± obovate to elliptic, margins corky-winged, irregularly toothed, faces smooth or warty, sometimes gland-dotted; pappi 0 (cypselae often each with apical tuft of white hairs). <b>x</b> = 18.</span><!--

|discussion=<p>Species 2 (1 in the flora).</p><!--
--><p>Traits that have been used to distinguish species and/or infraspecific taxa of dicorias in the flora (presence/absence of erect hairs on stems, shape, size, and toothing of distal leaves, size of cypselae, and relative development of inner phyllaries; A. Cronquist 1994) vary and combine so capriciously that I find no justification for recognition of more than a single, polymorphic species in the flora area.</p>
