SUMMARY
Stem thick, internodes short, 4.5-5.5 cm diam.; roots more or less dense, whitish to greenish, smooth; cataphylls lanceolate, 5-7 cm long, 0.6-0.8 cm wide, persisting as a mass of fibres. Leaves erect to slightly spreading; petiole 3.4-4.5 cm long, 0.3-0.5 cm diam., adaxially shallowly canaliculate with acute margins, abaxially rounded, the surface minutely white-punctate in fresh material, medium to dark glossy green; geniculum slightly thicker than the petiole, clear glossy green, 0.5-1 cm long; sheath 1.4-2 cm long; blade coriaceous, linear-elliptic to linear-oblong, acute to shortly acuminate at apex, obtuse to acute at base, 34-57 cm long, 2-4.5 cm wide, broadest at middle or slightly below, margins very weakly undulate in dry material; surface mat, medium to dark green, sometimes slightly glaucous or velvety, lower face mat, slightly paler, densely white-punctate in living plants; both faces drying mat, yellowish brown; midrib slightly prominent above, obtuse to acutely keeled below; venation almost invisible on both faces in living plants, becoming strongly conspicuous after drying, primary lateral veins 24-26 per side in dry leaves, arising from midrib at an angle of 30-50° arcuate, slightly prominent on surface, more so on lower face; interprimary veins slightly less prominent than primaries; tertiary veins prominent on both faces in dried leaves, reticulate veins prominulous when dry; collective vein 3-4 mm from leaf margin. Inflorescences usually pendent, much shorter than the leaves; peduncle 2.5-3 cm long, 0.4-0.8 cm diam., 1.2-1.5 times shorter than the petioles; spathe erect, inserted at an angle of 40-45° on the peduncle, coriaceous, lanceolate, 9.5-10 cm long, 2.3-2.5 cm wide, broadest slightly above the base, sometimes almost at middle, shortly acuminate at apex, obtuse at base, spathe margins meeting obtusely, outside semi-mat, medium green, densely white-punctate in fresh material, inside paler and less densely punctate; spadix brown to slightly purplish, stipitate for 5-6 mm, tapered, 7-9.2 cm long, 0.7-1.5 cm diam. at base, 4-5 mm diam. at apex, broadest near base; flowers rhomboidal, 1.5-2 mm long, 2.5-3 mm wide; 6-8 flowers visible in principal spiral, 6-7 flowers visible in alternate spiral; tepals mat; lateral tepals 0.6-1 mm wide, inner margins concave, outer margins 2-sided; pistils not emergent; stigma ellipsoid; stamens only partially covering the ovary, filaments not exerted, anthers 0.6-0.8 × 0.5-0.8 mm, thecae ovoid, 0.6-0.8 × 0.3-0.4 mm. Infructescence unknown.
