|discussion=<p><i>Linum macrocarpum</i> is known only from about 20 populations in Bay, Franklin, and Okaloosa counties in Florida; St. Tammany Parish in Louisiana; Hancock, Harrison, Jackson, and Stone counties in Mississippi; and Baldwin, Escambia, Mobile, and Washington counties in Alabama. Its range overlaps both varieties of <i>L. floridanum</i>, but <i>L. macrocarpum</i> may be distinguished by its larger capsules, larger seeds, and usually taller stems (B. A. Sorrie, pers. comm.).</p>
