    General Description
    Epiphyte; leaf scars obscured by dense roots and persistent cataphyll fibers; roots numerous, 2-5 mm thick; cataphylls moderately thin, 5-7 cm long, acuminate at apex, quickly turning reddish brown, weathering to subpersistent fibers. LEAVES spreading; petioles 4-19 cm long, 5-9 mm wide, stiff, almost triangular, sharply acute abaxially, broadly and sharply sulcate adaxially with a faint medial rib; geniculum 1-2 cm long; blades oblong-elliptic, coriaceous, slightly arched along the midrib, acute to abruptly short-acuminate at apex (the acumen minutely apiculate), acute at base, 24-40 cm long, 6-11 cm wide, broadest near the middle or slightly above, the margin flat or broadly undulate; upper surface glossy, lower surface semiglossy, with moderately dense, dark glandular punctations; midrib convexly raised above, narrowing and diminishing towards apex, sharply acute below, usually with a distinct, erect rib; primary lateral veins 20-35 per side, departing midrib at ca. 60° angle, slightly sunken above, obscure below, more or less straight to the collective vein; collective vein arising from the base, mostly straight, 5-7 mm from margin, slightly sunken above, obscure below. INFLORESCENCE erect-spreading, shorter to longer than the leaves; peduncle 6-44 cm long, 4-8 mm wide, sharply triangular, the sharpest margin continuous with the decurrent edges of spathe, flexible to more or less stiff; spathe coriaceous, yellow-green, sometimes tinged purplish (B & K Yellow-green 7/10) at anthesis, lanceolate-elliptic to broadly lanceolate or oblong-elliptic, 3-11 cm long, 2.2-4.1 cm wide, broadest near point of insertion, short-acuminate at apex (the acumen hooked), acute and slightly inequilateral at base, decurrent 5-15 mm, inserted at 70° angle on peduncle, spreading, meeting on peduncle at 60-90° angle; the stipe 1-3 mm long in back, 6-9 mm diam., darker green than peduncle; spadix pale green (B & K Yellow-green 7/10) at anthesis, 7.5-16.5 cm long, 8-13 mm diam. at base, 5-9 mm diam. at apex; flowers square or rhombic to weakly 4-lobed, 3-4.1 mm long, 2.5-3.9 mm wide, ca. 6 flowers visible m the principal spiral, ca. 5 flowers visible in the alternate spiral, the sides straight to shallowly sigmoid; tepals green, semiglossy, the lateral tepals 2-2.2 mm wide; pistil weakly emergent at anthesis, pale green, the stigma oblong, with minute droplet just before pollen is visible, the droplets remaining after pollen appears; stamens never fully exserted, squeezing minute amounts of pollen out between tepals and pistil, the pollen held at edge of droplet; pollen white. INFRUCTESCENCE spreading to pendent, the spathe much shorter than the spadix, spreading; spadix 12-24 cm long, to 2.5 cm diam.; berries subglobose, flattened at apex, pale lavender white, ca. 7 mm long, 6-7 mm wide, 4-5 mm thick, with a whitish circular area ca. 2 mm wide around the stigma; seeds 6, narrowly ovoid, white, ca. 2 mm long.
