--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> perennial, cespitose, dull green to olive when dry, to 4.2 dm, not glaucous; rhizomes scarcely discernable. <b>Stems</b> simple, often purplish, almost wiry, with very narrow or scarcely discernable wings, 0.9–2 mm wide, usually glabrous, margins usually entire to denticulate apically, similar in color and texture to stem body. <b>Leaf</b> blades usually glabrous, bases not persistent in fibrous tufts. <b>Inflorescences</b> borne singly; spathes mostly purplish, glabrous to slightly scabrous (in southern populations), keels entire; outer 34–52 mm, 14–31 mm longer than inner, usually tapering evenly towards apex, margins basally connate (0.7–)1–2.7 mm; inner with keel evenly curved to occasionally gibbous basally, hyaline margins 0.1–0.3 mm wide, apex acuminate to acute, ending 0.5–3.2 mm proximal to green apex. <b>Flowers</b>: tepals dark blue or bluish violet, occasionally white, bases yellow; outer tepals 9–12.5 mm, apex emarginate to rounded, aristate; filaments connate ± entirely, stipitate-glandular basally; ovary similar in color to foliage. <b>Capsules</b> tan to light brown with purplish tinge apically, ± globose, 3.2–5.5 mm; pedicel spreading to erect. <b>Seeds</b> globose to obconic, lacking obvious depression, 0.8–1.5 mm, usually granular. <b>2n</b> = 32.</span><!--

|discussion=<p><i>Sisyrinchium mucronatum</i> can be a difficult species to identify, especially in the north. Herbarium specimens seem to indicate that morphologically it may approach <i>S. septentrionale</i> in central Canada, and narrow specimens of <i>S. montanum</i> in the northeast. Fresh material, however, reveals that <i>S. septentrionale</i> tends to have much paler flowers with no emarginate apices and much longer outer spathes, and that <i>S. montanum</i> usually has much wider stems, leaves, and bracts, and the outer tepals have emarginate to retuse apices. Southeastern populations of <i>S. mucronatum</i> tend to be more scabrous while northwestern populations have less purple in the spathes.</p>
