SUMMARY
Epiphytic; stem erect; cataphylls coriaceous, 17- 51 cm long, lanceolate, obtuse to mucronate at apex, light green, drying light tan (B & K yellow-red 9/ l0), persisting with the apex remaining intact. LEAVES spreading; petioles 14-63 cm long, 7- 12 mm diam., quadrangular, flattened to broadly and sharply sulcate adaxially, the margins sharply raised, sharply 2-3-ribbed abaxially; geniculum thicker and paler than petiole, becoming fissured transversely with age, (1.3)2-7 cm long; blades coriaceous, oblong-lanceolate to oblong or oblongtriangular, rounded to obtuse to acuminate at apex, rounded to truncate at base, 37-140(160) cm long, 8-38(45) cm wide, the margins undulate; upper surface matte to semiglossy, medium green, lower surface semiglossy to glossy, paler; midrib obtusely angular at base, becoming narrowly raised toward the apex above, prominently higher than broad at base, becoming prominently convexly raised toward the apex below, paler than surface above and below; primary lateral veins more than 20 per side, departing midrib at 45-75º angle, prominently and narrowly raised above and below; tertiary veins obscure above, raised and darker than surface below; collective vein arising in the lower half of the blade, sunken above, raised below, less prominent than primary lateral veins, 2-3 mm from margin. INFLORESCENCES spreading, shorter than leaves; peduncle 13-25 cm long, 0.6-0.7 x as long as petiole, terete; spathe usually recurled and twisted, prominently reflexed, subcoriaceous, green or violet-purple, narrowly ovate to oblong-lanceolate,10.5-32 cm long, 3-7 cm wide, inserted at 45º angle on peduncle, acuminate at apex, rounded to subcordate at base; spadix yellow-green, long-tapered, 16-38 cm long, 9-12 mm diam. near base, 6-7 mm diam. near apex; flowers rhombic to 4-lobed, 2.5-4 mm in both directions, the sides sigmoid; 7-1 1 flowers visible in principal spiral, ca. 9 in alternate spiral; tepals matte to semiglossy; lateral tepals ca. 2.7 mm wide, the inner margins convex; pistils emergent, green, violet-purple at apex; stigma ellipsoid, ca. 1 mm long, stamens emerging promptly throughout length of spadix in a complete sequence, grouped in a circle around the pistil; anthers 1 -1.1 mm long, 1 -1.2 mm wide; thecae oblong to narrowly ovoid, slightly divaricate; pollen cream. INFRUCTESCENCE with spadix to 50 cm long; berries probably orange at maturity, oblonglinear, acute to blunt at apex, 10-14 mm long, ca. 3.5 mm diam.; seeds 2 per berry, 3.4-3.6 mm long, ca. 1.6 mm diam., with a minute appendage at both ends.
