|discussion=<p>Species ca. 50 (2 in the flora).</p><!--
--><p>Although the taxonomy of <i>Rhinanthus</i> in the Old World is complex, the taxa found in North America are reasonably distinct. The subapical teeth on the adaxial corolla lip have been described as galea or nipples; the term teeth is used in this account. Leaf measurements are for mid-stem leaves; calyx features are for post-anthesis calyces.</p><!--
--><p>The European species <i>Rhinanthus</i> serotinus (Schönheit ex Halácsy & H. Braun) Oborný has been reported from Maine (E. Hultén and M. Fries 1986); the authors have found no specimens to substantiate this report. If it were to be encountered in North America, it would key to <i>R. major</i>, from which it can be distinguished by having narrowly triangular bracts and glabrous calyces as in <i>R. minor</i>.</p>
