Herbs, perennial, cespitose, pale olive green when dry, to 3.4 dm, rarely glaucous. Stems branched, with 1–2 nodes, 1.7–3.2 mm wide, glabrous, margins white or translucent-cartilaginous; first internode 11–41 cm, longer than leaves; distalmost node with 2 branches. Leaf blades glabrous, bases not persistent in fibrous tufts. Inflorescences borne singly; spathes green, obviously wider than supporting branch, glabrous, keels entire to denticulate; outer 14–18 mm, 3.8 mm shorter to 0.5 mm longer than inner, tapering evenly towards apex, basally connate 4–7 mm; inner with keel evenly curved to straight, hyaline margins 0.5–0.8 mm wide, apex abruptly broadened, ending 0.5–2.3 mm proximal to green apex. Flowers: tepals bluish violet, bases yellow; outer tepals elliptic to oblanceolate, 9–12 mm, apex rounded to slightly emarginate, aristate; filaments connate ± entirely, stipitate-glandular basally; ovary similar in color to foliage. Capsules beige to tan, globose, 4.3–6 mm; pedicel erect to ascending. Seeds globose to obconic, lacking obvious depression, 0.8–1.3 mm, rugulose. 2n = 32.
