    General Description
    Epiphytic or terrestrial, sometimes epipetric; stem short or elongate, to 60 cm long, 1-3 cm wide; leaf scars inconspicuous, obscured by root mass, 1 cm high, 1.2 cm wide; roots numerous, dense, spreading, green to whitish, smooth to densely pubescent when dried, short, bluntly tapered, 1-7.5 cm long, (1)2-4 mm diam.; cataphylls membranous to subcoriaceous, lanceolate, prominently 1 -ribbed throughout, 5.5-12 cm long, acuminate at apex with subapical apiculum 1-2 mm long, light green, drying thin, yellowish to pale tan (B & K yellow 7/5), persisting ± intact, eventually as fine linear fibers. LEAVES erect to erect-spreading; petioles (2.5)5-15 cm long, 4-9 mm diam., subterete to C-shaped to D-shaped, flattened to narrowly or obtusely sulcate adaxially, the margins blunt, rounded abaxially, the surface dark green, pale-speckled; geniculum slightly thicker than petiole, 1-2.5 cm long; sheath for 3-4 cm long; blades subcoriaceous, narrowly to broadly elliptic to broadly oblanceolate to narrowly obovate, acute to short acuminate at apex (the acumen downturned, inrolled), obtuse to acute or attenuate at base, (1 2)22-55 cm long, 10-19 cm wide, broadest at or above the middle, the margins flat to broadly undulate; upper surface glossy to semiglossy, occasionally matte, medium to dark green, lower surface matte to weakly glossy, moderately to conspicuously paler; midrib above raised and paler than to concolorous with the surface, below prominently and obtusely to acutely raised at base, becoming convexly raised toward the apex and slightly paler than surface; primary lateral veins 10-25 per side, departing midrib at 40-70° angle, straight to weakly arcuate to the collective vein, weakly raised near the midrib, becoming sunken in grooves toward the margin; interprimary veins weakly sunken above, weakly raised below; tertiary veins weakly sunken above, raised below; reticulate veins obscure; collective vein arising from near the base, sunken above, raised below, paler than surface, 5-11 mm from margin. INFLORESCENCES erect, equalling or longer than leaves; peduncle 18.5-54.7 cm long, 3-5 mm diam., 2.5-5 x as long as petiole, green, terete; spathe spreading to reflexed at an acute to almost right angle from spadix, coriaceous to subcoriaceous, light to dark green, sometimes tinged with red or maroon at margins, lanceolate to ovate-lanceolate, sometimes elliptic, 4.5-12.5 cm long, 1-3 cm wide, broadest usually in the lower third (sometimes at or near the middle), inserted at 35- 45° angle on peduncle, abruptly acuminate at apex (the acumen tightly inrolled, 6 mm long), acute to acuminate at base, the margins meeting at 60-80° angle; stipe to 17-20 mm long in front, 0-1 mm long in back; spadix bluish green to green to yellow-green, also reported as creamy and tan, tapered, erect, held at 140-170° angle from peduncle, 4-8.5 cm long, 6-10 mm diam. near base, 3-7 mm diam. near apex; flowers square, 2.4-3.2 mm in both directions, the sides moderately straight parallel to spiral, straight to jaggedly sigmoid perpendicular to spiral; 4-7 flowers visible in principal spiral, 9-11 in alternate spiral; tepals covered with thin, matte, bluish green, waxy bloom, few droplets present at anthesis; lateral tepals 1.3-2 mm wide, the inner margins broadly convex, the outer margins 2-3-sided; pistils weakly emergent at anthesis, matte covered with waxy bloom, green, becoming brown; stigma oblong-ellipsoid, 0.6-0.7 mm long, brushlike and depressed medially before droplets emerge; stamens emerging in a prompt, regular, complete sequence from the base, inclined slightly inward over the stigma; anthers creamy white to orange, 0.5-0.6 mm long, 0.6-0.8 mm wide; thecae oblong-ovoid, scarcely divaricate; pollen white. INFRUCTESCENCE with spathe persisting; spadix 6.5- 8.5 cm long, 1.8-2.5 cm diam., with berries scattered throughout; berries green, becoming red and eventually purple in the apical half, obovoid-oblong to ellipsoid-obovoid, long-acuminate toward the apex, rounded at apex with radial ridges, 7.5-12.3 mm long, 4.2-5 mm diam near base, toward the apex narrowing to 1.7-2.5 mm diam.; pericarp thin, transparent; mesocarp gelatinous with moderate number of raphide cells; seeds 2 per berry, yellowish, oblong-ovoid, flattened, 5.3-5.5 mm long, 3 mm diam., 1.5-1.8 mm thick, enveloped by transparent, sometimes amber, gelatinous, sticky substance.
    Tropical moist, premontane wet and tropical wet forest life zones.
