Linum subteres
Linum schiedeanum
Linum subteres is most closely related to L. vernale; it has lemon yellow petals, rather than orange to salmon-colored with a maroon base, and relatively thick, crowded, broad basal leaves (C. M. Rogers 1984). Leaves on the proximal half of each stem are closely spaced and imbricate; distal branches and inflorescence are widely spaced and subtended by closely appressed, relatively long, narrow leaves or bracts, giving the upper part of the plant a leafless look.

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.
