    General Description

    Appressed epiphyte or sometimes terrestrial; STEMS mostly 1.5-2 m long; internodes short near the apex, longer than broad lower down on the stems, usually 4-10 cm long, 2-2.3(-3) cm diam., dark brown, semiglossy on young stems, soon becoming scurfy, minutely transverse-fissured, drying reddish brown and deeply sulcate; petioles 21-41 cm long (averaging 37 cm), sheathed to the geniculum; sheath deciduous or with the margins fibrous to semi-intact with fragments of epidermis persisting, the margins sometimes incurled; geniculum sharply sulcate with the margins thin and undulate; blades elliptic, abruptly acuminate at apex, acute to obtuse or rounded but weakly attenuate at the base, 30-50 cm long, 15-25 cm wide (averaging 44 X 23 cm), 1.8-2.4 times longer than broad, (1.0-)1.2-1.5 times longer than the petioles, broadest at the middle or below the middle, nearly equilateral to moderately inequilateral, one side 1-3.0 cm wider, subcoriaceous, dark green and semiglossy above, much paler and matte below; midrib much paler and sunken and marginally discolorous above, thicker than broad and slightly paler below; primary lateral veins very numerous, mostly 50-80 per side, 3-8 mm apart, arising often at an acute angle then spreading 70°-95° angles then weakly curved toward the margin, narrowly sunken and weakly quilted above, convex, and slightly paler beneath; interprimary veins sometimes almost as prominent as the primary lateral veins, darker than surface, usually 1 or 2 (sometimes 3, rarely none); minor veins usually 1, sometimes 2 between adjacent primaries and the interprimaries; surface minutely reddish brown dotted, sometimes appearing pale-speckled; INFLORESCENCES solitary, erect; peduncle 15-20 cm long, drying ca. 6 mm diam.; spathe boat-shaped, to 13 cm long, acute at apex, drying dark brown; spadix gray to greenish gray, matte, sessile, 10-14 cm long, drying 14-19 mm diam. Flowers 16-20 per spiral, 1.3-1.5 mm x 1.0-1.3 mm diam.; irregularly trapezoidal to irregularly 6-sided, often with the sides perpendicular to the spirals gradually sigmoid with two opposite corners of the spiral acute and the alternate corners broadly rounded, the surface matte, with a thin, fine, frost-like epidermis; stigma ellipsoid, 0.8-1.0 mm long, 0.3-0.4 mm wide, prominently raised and darker than the surface of the pistil; stamens with anthers 0.8-1.0 mm long, 0.5-0.9 mm wide, thecae not at all divaricate. INFRUCTESCENCES to ca. 2 cm diam. and 20 cm long; seeds, round, only slightly flattened, dark brown, 1 mm diam.
