|discussion=<p>As indicated by R. L. McGregor (1985), <i>Camelina alyssum</i> is known from the above states only from old collections, and, apparently, the species has not been collected again during the past five decades. Although we have not examined all of his cited specimens, those on which the Missouri and Nebraska records are based belong to <i>C. sativa</i>.</p>
