Herbs, perennial, cespitose, yellowish green to olive when dry, to 4.5 dm, not glaucous. Stems apparently simple, wiry, wings present as slight ridges, 0.5–1 mm wide, glabrous, margins minutely denticulate, similar in color and texture to stem body. Leaf blades glabrous, bases not persistent in fibrous tufts. Inflorescences usually paired, closely subtended by long, bractlike leaf that often obscures first (inner) inflorescence, sessile or second (outer) with branch to 6.6 mm; spathes often purplish, glabrous, keels entire; outer 12.1–14.7 mm, 0.9 mm shorter to 2.7 mm longer than inner, usually tapering evenly towards apex, margins distinct or connate basally to 1.5 mm; inner with keel straight or evenly curved, hyaline margins 0.2–0.4 mm wide, apex acute to occasionally obtuse, ending 0.2–1.4 mm proximal to green apex. Flowers: tepals pale blue to bluish violet, bases yellow; outer tepals 7.7–12 mm, apex emarginate, aristate; filaments connate ± entirely, glabrous; ovary similar in color to foliage. Capsules tan or light brown, ± globose, 2–3.3 mm, glabrous; pedicel loosely erect or spreading. Seeds globose to obconic, lacking obvious depression, 0.8–1.2 mm, rugulose.
