|discussion=<p>Species 1.</p><!--
--><p><i>Coelophragmus</i> was described as consisting of two species. The type of one, C. umbrosus O. E. Schulz (1924), belongs in <i>Dryopetalon</i> and is conspecific with the type of <i>D. runcinatum</i> A. Gray (1853). Because removal of that species does not constitute effective lectotypification of the genus name, <i>C. auriculatus</i> O. E. Schulz is designated here as type of <i>Coelophragmus</i>.</p><!--
--><p>Although <i>Coelophragmus auriculatus</i> was originally described as <i>Sisymbrium</i> auriculatum and recognized as such by every North American botanist, including E. B. Payson (1922) and R. C. Rollins (1993), the species clearly is not a <i>Sisymbrium</i> (S. I. Warwick et al. 2002, 2006b), a genus almost exclusively restricted to the Old World. <i>Coelophragmus</i> is recognized herein as a monotypic genus, and its affinities are nearest <i>Dryopetalon</i> (I. A. Al-Shehbaz et al. 2006). It is unique among all North American genera of the family by having fruit septums deeply partitioned between seeds.</p>
