Acaulescent, rosulate herb. Stem thick, internodes short, 3 – 5 cm diam.; roots greyish white to greenish; prophylls weakly two-keeled, 1 – 2 × 1.5 – 2 cm, intermediate cataphylls lanceolate, 4.5 – 5.5 × 0.5 – 1 cm, both kinds persisting as a mass of coarse fibres. Leaves spreading; petioles 4 – 6(– 11) cm long, 0.5 – 0.7 cm diam., Ushaped, flattened with obtuse margins adaxially, rounded abaxially, medium to dark matte green when fresh, surface minutely white-speckled; basal geniculum thicker than the petiole, clear matte green when fresh, 0.6 – 0.8 × 0.7 – 0.8 cm, apical geniculum thicker than the petiole, clear matte green when fresh, 0.8 – 1.5 cm long; sheath 1.5 – 2 cm long; blades chartaceous, elliptic, acuminate at apex, obtuse to truncate at base, 19 – 33.5 × 4.5 – 7.7 cm, broadest at middle or slightly below; the margins very weakly undulate upon drying; upper surface matte, medium to dark green, lower surface matte, paler; both surfaces drying pale brown; midrib slightly prominent above, obtuse to keeled below, in both surfaces densely covered with white speckles; venation poorly visible on both sides in both fresh and dried leaves, primary lateral veins numerous (more than 20), impossible to separate from the interprimary veins, departing midrib at 50 – 65° angle, arcuate, slightly prominent on upper surface, raised below; secondary veins prominulous in both surfaces when dry, reticulate veins almost invisible to slightly raised below; collective vein 5 – 6 mm from leaf margin. Inflorescences usually pendent after anthesis, much shorter than the leaves; peduncle 1 – 2 cm long, 0.5 – 0.7 cm diam., 2 – 4 × shorter than the petioles; spathe erect, chartaceous, ovate, semimatte medium green outside, concolorous or a little glaucous inside, densely whitespeckled on both surfaces when fresh, 3 – 5 × 1.5 – 2.5 cm, broadest near the base, sometimes almost at middle, inserted at 45° angle on the peduncle, cuspidate to acuminate at apex, obtuse at base, spathe margins meeting obtusely to almost at 180°; spadix greenish to greyish green, stipitate for 4 – 5 mm, tapered, 2.6 – 4 cm long, 0.6 – 1 cm diam. at base, 3 – 5 mm diam. at apex, broadest near base; flowers rhomboidal, 3 – 3.5 mm long, 2.8 – 3 mm wide; 7 – 8 flowers visible in principal spiral, 5 – 6 flowers visible in alternate spiral; tepals matte, lateral tepals 0.9 – 1 mm wide, inner margins straight, the outer margins 2-sided; pistils emergent, stigma rounded; stamens not covering the stigma at all, filaments not exerted, anthers 0.5 – 0.7 × 0.4 – 0.6 mm, thecae ovoid, 0.5 – 0.7 × 0.2 – 0.3 mm.
