--><span class="statement" id="st-undefined" data-properties=""><b>Annuals </b>or perennials, 5–100+ cm; taprooted or rhizomatous (roots producing tuberiform swellings in <i>P. grandiflorus</i>). <b>Stems</b> usually 1, sometimes 2–5+, erect, unbranched or branched proximally and/or distally, glabrous or pilosulous. <b>Leaves</b> basal or basal and cauline; basal ± petiolate, distal usually sessile; blades oblong, elliptic, or ovate to lanceolate or linear, margins entire or dentate to pinnately lobed (faces usually glabrous, sometimes pilosulous near margins). <b>Heads</b> borne singly or in loose, corymbiform arrays. <b>Peduncles</b> not inflated distally, sometimes bracteate. <b>Calyculi</b> of 3–13+, deltate to subulate or filiform bractlets. <b>Involucres</b> cylindric, 4–5[–8+] mm diam. <b>Phyllaries</b> 8–21+ in ± 2 series (reflexed in fruit), linear, equal, margins often scarious, apices acute (often thickened or bearing keel-like flaps near tips). <b>Receptacles</b> ± convex, pitted, glabrous, epaleate. <b>Florets</b> (20–)30–150+; corollas yellow to whitish. <b>Cypselae</b> reddish brown to stramineous, bodies ± fusiform, beaks (± concolorous with bodies) ± filiform, fragile, grooves (or broad ribs) 5, faces transversely rugulose, glabrous; pappi (borne on discs at tips of beaks) persistent, double: outer coroniform (of whitish, relatively short, spreading, sometimes curly, hairs), inner of 80–120+, rufous to stramineous, subequal, barbellulate bristles in 2–3+ series. <b>x</b> = 6.</span><!--

|discussion=<p>Species 1, 4, or 5 (4 in the flora).</p><!--
--><p>Some plants from Mexico that have been called <i>Pyrrhopappus</i> multicaulis de Candolle (type from Mexico) may be distinct at species rank from <i>P. pauciflorus</i> (see R. McVaugh 1984).</p><!--
--><p>Almost all botanists who have dealt with the biology or floristics of pyrrhopappuses have remarked similarities among the taxa and/or difficulties with identification of some specimens. Some botanists have noted that “interspecific” hybridizations are common (D. K. Northington 1974; B. L. Turner and K. J. Kim 1990; and works cited therein).</p>
