Linum puberulum
Linum schiedeanum
Corollas of Linum puberulum 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 L. puberulum, the styles seem to be eccentric. C. M. Rogers (1968) noted that L. puberulum is the only hairy species of Linum in western North America with united styles; its gray indument and complete false septa differentiate it from L. vernale, which is glabrous and has incomplete false septa. Linum puberulum is fairly common in the Rocky Mountain foothills and high plains; it occurs in the mountains in the eastern Mojave Desert.

Linum schiedeanum has yellow, broadly bowl-shaped corollas, yellow stamens, and yellow styles and stigmas. The styles are broadly incurved, following the line of the petals, and are held outside the ring of stamens. Staminodia in L. schiedeanum are low, deltoid, and usually two between adjacent stamens, sometimes one or none. J. R. McDill (2009) reported that L. schiedeanum formed a group (L. schiedeanum group) with four other species with whorled leaves occuring from the Guadalupe Mountains of western Texas south to Veracruz. C. M. Rogers (1984) noted that a compact form of L. schiedeanum from sunny areas might warrant more study.
