|discussion=<p>In the flora area, <i>Dryopetalon viereckii</i> is known from Cameron, Hidalgo, Jim Hogg, Kinney, La Salle, McMullen, Starr, Webb, and Zapata counties. It is highly variable in its leaf, fruit, style, pedicel, and petal lengths, density of indumentum, development of auricles, and division of basal leaves. This variation, which is continuous, has been the basis for dividing the species into varieties.</p>
