|discussion=<p>Plants of Orthosia scoparia may appear densely leafy or completely leafless and may bear flowers in either condition. The flowers of O. scoparia are smaller than those of the regionally co-occurring species of Metastelma and Pattalias and, unlike those in Metastelma, the corollas of O. scoparia are completely glabrous. Orthosia scoparia just enters South Carolina (Beaufort County), where it is rare and considered to be of conservation concern.</p>
