LEAVES 18 - 47 cm long with petioles 4 - 11.2 cm long, 2 - 3 mm diam., sharply flattened adaxially with faint medial rib, narrowly rounded abaxially; geniculum 0.5 - 1.5 cm long, slightly swollen, with longitudinal wrinkles and darker than petiole; blades narrowly elliptic, 14 - 24.5 cm long, 3.6 - 5.9 cm wide, 3.3 - 5.1 times longer than broad (averaging 3.9), 1.7 - 4.1 times longer than petiole (averaging 2.3), acuminate at apex, narrowly acute to attenuate at base; midrib concolorous, narrowly and acutely rounded above and below, eglandular above, sometimes glandular along its lower border on lower surface; primary lateral veins 8 - 13 pairs, arising from the midvein at 40° - 50° angles, concolorous and obscure above, very finely raised and barely discernable below, often undulate upon drying; collective veins arising from the base, 2 - 5 mm from the margin, slightly more prominent than primary lateral veins; upper surface drying medium grayish green, semiglossy, minutely aerolate-ridged, eglandular (but with dark removable punctations); lower surface drying medium brownish green, semiglossy, minutely granular-ridged and conspicuously dark glandular-punctate (punctations concave medially). INFLORESCENCE 11 - 41 cm long with peduncles 7.6 - 20.1 cm long (averaging 24.4), 1 - 3 mm diam.; spathe green, usually spreading, sometimes reflexed 2.3 - 3.5 cm long, 3 - 7 mm wide; spadix green, sessile, narrowly long-tapered, 3.4 - 21.2 cm long (averaging 11.9), 3 - 8 mm diam.; flowers rhombic, sometimes mounded, 3(- 4) visible per spiral, 4.1 mm long, 2.5 mm wide; tepals surface papillate, lateral tepals typically much broader than wide, 1.6 - 2.3 mm wide, inner margins slightly rounded, outer margins 2-sided.
