|discussion=<p>Corollas of <i>Linum puberulum</i> are broadly bowl-shaped. The filaments and styles are pale pink; the stigmas are dark maroon. The pollen is bright yellow; on herbarium specimens, the anthers are golden yellow to orangish yellow, drying darker. In some flowers of <i>L. puberulum</i>, the styles seem to be eccentric. C. M. Rogers (1968) noted that <i>L. puberulum</i> is the only hairy species of <i>Linum</i> in western North America with united styles; its gray indument and complete false septa differentiate it from <i>L. vernale</i>, which is glabrous and has incomplete false septa. <i>Linum puberulum</i> is fairly common in the Rocky Mountain foothills and high plains; it occurs in the mountains in the eastern Mojave Desert.</p>
