Description Robust, rhizomatous herbs; rhizome 2.5–3 cm diameter. Cataphylls absent. Culms sometimes present, if present, 1- to several, erect, lateral, 0.8–5 cm × 3–5 mm, terete to subtrigonous, glabrous, greenish. Leaves basal, crowded and strongly 3-ranked, up to 170 cm long, leaf-blade linear, 150–165 × 2–4 cm, apex very gradually narrowed, base gradually narrowed into sheath, thickly coriaceous, light to dark green, 3-nerved, secondary nerve indistinct, inverse-w in cross-section, indistinctly septate-nodulose when dry, margins coarsely serrulate, pseudopetiole absent, sheath lanceolate, 7–5.5 × 1.8–2.2 cm, apex very gradually narrowed, coriaceous to thickly coriaceous, greenish to mid brown. Involucral bract 3–5, glumaceous, ovate to lanceolate, 2–3 × 0.8–2.2 cm, basal bract longest, obtuse, coriaceous, yellowish brown, glabrous, nerves indistinct. Inflorescence sessile or terminal, elliptic to lanceolate, 1–3 spikes, spikes remaining ± obscured by involucral bracts even at maturity, linear, 1.3–2.0 × 1.5–2.4 cm, greenish brown, distinct when involucral bracts removed, spiciform bracts lanceolate, 1.5–3 × 1–1.5 cm, subcoriaceous, greenish or brown, nerves indistinct; floral bract 6, free, lowest 2 bracts linear to linear lanceolate, 2.0–2.5 × 1 mm flat, glabrous, staminate flowers 3, anthers linear, 8 mm long, filament up to 15 mm long, stigma branches 3, style up to 2 cm long. Fruit obovoid, 1.1 × 0.3 cm, apex apiculate, elongated, base stipitate, exocarp succulent, thin, without sculpturing, dark brown or black, costae absent. [details]
