    General Description
    Terrestrial; stem moderately slender, to at least 11 cm long, 0.8-1.5 cm diam.; roots moderately numerous, spreading, green, drying grayish to pale brown, ± villous, especially when young, elongate, somewhat tapered, sometimes branching, ca. 3-25 cm long, 2-8 mm diam.; cataphylls subcoriaceous, lanceolate to broadly lanceolate, 7-13 cm long, acute to rounded at apex, yellow-green, tinged with red, drying brown to reddish brown (B & K yellow-red 4/10), persisting intact to semi-intact, rarely as fine linear fibers, eventually deciduous. LEAVES erect to spreading; petioles 22-42 cm long, 3-6 mm diam., erect to erect-spreading, subterete to broader than thick, bluntly and shallowly sulcate adaxially, rounded abaxially, the surface prominently pale-speckled; geniculum much paler and somewhat thicker than petiole, becoming fissured transversely with age, 0.5-2 cm long; blades coriaceous, linear-oblong, narrowly acute and mucronate at apex, acute to obtuse to narrowly rounded at base, 38-60(100) cm long, 2.2-7 cm wide, broadest at or near the middle (12.6- 17.6 x longer than the petiole), the margins flat to somewhat undulate; upper surface matte to weakly glossy, dark green, lower surface matte, conspicuously paler; both surfaces drying matte, green to yellowish green; midrib convexly raised, paler than surface above, ale-speckled like petiole, higher than broad at base, becoming prominently convex toward the apex below, moderately paler than surface and pale-speckled like petiole; primary lateral veins 18-26 per side, departing midrib at 45-60° angle, straight to arcuate, weakly sunken to obscure above, darker than surface below; interprimary veins obscure above, almost as conspicuous as primary lateral veins below; tertiary veins obscure above, weakly visible below; reticulate veins not visible; collective vein arising from the base, equally as prominent as primary lateral veins, 1-4(6) mm from margin. INFLORESCENCES erect, shorter than leaves; peduncle 27-50 cm long, 2-4 mm diam., 0.8-1.3 x as long as petioles, pale reddish, drying greenish to brownish, terete; spathe spreading-recurled, subcoriaceous, yellow-green tinged with red on the midline, oblong-lanceolate to linear, ca. 3.5- 6.5 cm long, 0.8-1.3 cm wide, broadest near the base, acute to abruptly acuminate at apex (the acumen apiculate, 4 mm long), acute at base; spadix maroon (B & K red-purple 2/5), dark brown when dried, slightly tapered, subsessile, somewhat curved, held at 150° angle from peduncle, 4-10(12) cm long, 4-5(6) mm diam. near base, 2- 3 mm diam. near apex; flowers ± square to almost 4-lobed, 2-2.4 mm in both directions, the sides ± straight to jaggedly sigmoid; 3-6 flowers visible in principal spiral, 6-9 in alternate spiral; tepals matte, very minutely and densely papillate, punctate, with few droplets appearing as stamens emerge; lateral tepals 1-1.2(2) mm wide, the inner margins straight to convex, the outer margins 2- rarely 3-sided; pistils semiglossy, minutely papillate, emergent before stamens emerge, dark maroon; stigma ellipsoid, 0.3-0.7(0.9) mm long, depressed medially; stamens emerging in a regular sequence from the base, arranged shortly above the tepals, the laterals preceding the alternates by 14-15 spirals, held in a circle around the pistil; anthers white, drying white to brown, 0.5-0.7 mm long, 0.6-1 mm wide; thecae ovoid, not divaricate; pollen white. INFRUCTESCENCE not seen.
    Lower montane subtropical moist, lower montane subtropical wet, and subtropical moist forest life zones.
