|discussion=<p><i>Flaveria campestris</i> is distinguished by subglomerulate capitulescences with 5–6(–8) florets per head, subtended by 3 leafy bracts, keeled phyllaries, and linear-lanceolate leaves with serrate or spinulose-serrate margins, and its distribution. The prevalence of <i>F. campestris</i> fluctuates greatly from year to year, generally depending on the existence of wet, saline habitat.</p>
