|discussion=<p>In the United States, <i>Flaveria bidentis</i> often occurs on ballast and waste ground near wharfs and the shore, locations that suggest its introduction from sailing vessels. The species is widespread and well established in South America, where it is thought to be native. Its floral structure appears to be the least advanced among the annual species of <i>Flaveria</i>, the heads being in somewhat scorpioid arrays. Distinguishing characteristics are 3(–4) phyllaries, 2–8 florets per head, reduced ray corollas, pubescent stems, and lanceolate-elliptic, bluish green, sometimes pubescent leaves. <i>Flaveria bidentis</i> is probably most closely related to <i>F. campestris</i> and <i>F. trinervia</i>.</p>
