Stems branched or rarely simple, with 1–2(–3) nodes, 0.7–2 mm wide, glabrous, margins usually entire, similar in color and texture to stem body; first internode 2–10 cm, usually shorter than leaves; distalmost node with 1–2 branches. Leaf blades glabrous, bases not persistent in fibrous tufts. Inflorescences borne singly; spathes green, obviously wider than supporting branch, glabrous, keels usually entire; outer 13–32.2 mm, 2–8.2 mm longer than inner, tapering evenly towards apex or occasionally slightly constricted proximal to apex, margins basally connate 2.3–6.7 mm; inner with keel evenly curved to straight, hyaline margins 0.2–0.3 mm wide, apex acute, occasionally erose, ending 0.3–4.6 mm proximal to green apex. Flowers: perianth flaring distally, campanulate basally; tepals maroon or pink to lavender-rose with purple stripes, or yellow with rosy purple bases; outer tepals 5–11 mm, apex acute, rarely aristate; filaments connate basally, occasionally to 1/2 their length, basally inflated and stipitate-glandular 0.5–0.8 mm; ovary similar in color to foliage. Capsules tan with purplish sutures and sometimes apex, ± globose, 2.1–4.2 mm; pedicel spreading to recurved. Seeds ± globose, sometimes with slight depression, 0.5–1 mm, rugulose. 2n = 32.
