|discussion=<p>Species 19 (1 in the flora).</p><!--
--><p><i>Antirrhinum</i> is sometimes treated as a larger genus including both the species of Mediterranean Europe and the species of western North America (D. M. Thompson 1988). Here, the North American species are treated in five genera, <i>Howelliella</i>, <i>Mohavea</i>, <i>Neogaerrhinum</i>, <i>Pseudorontium</i>, and <i>Sairocarpus</i>, believed to be more closely related to one another than to the European species (D. A. Sutton 1988). There is not yet enough evidence to resolve these relationships; DNA sequence data seem to indicate that the European and North American species are sister groups and that there are at least two groups of closely related species among the American taxa (R. K. Oyama and D. A. Baum 2004; M. Fernández-Mazuecos et al. 2013).</p><!--
--><p><i>Antirrhinum</i> is distinguished from the segregate genera by the radially symmetric seeds, terminal (versus oblique) styles, and flowers more than 2 cm.</p>
