    General Description
    Description based on dried material only. Epiphytic on rotten logs; stem unknown; cataphylls ca. 7 cm long, apparently persisting as weathered pale fibers. LEAVES erect-spreading; petioles 34.5- 42 cm long, 6-7 mm diam., sulcate with the margins apparently acute, apparently acutely l –ribbed abaxially; geniculum ca. 1 cm long; sheath 4.5 cm long; blades subcoriaceous, broadly elliptic, acuminate at apex, long-attenuate at base, 57-61 cm long, 18-19.5 cm wide, broadest at or near the middle, the margins flat, both surfaces yellow to olive-green; midrib convexly raised above, prominently raised and apparently acutely angled toward the base below; primary lateral veins 12-16 per side, departing midrib at 50-80° angle, slightly arcuate to the collective vein, weakly raised above and below; interprimary veins much less to almost as conspicuous as primary lateral veins; reticulate veins weakly raised; collective vein arising from the base, equally as prominent as primary lateral veins, 10-16 mm from margin. INFLORESCENCES erect; peduncle 74-93 cm long, 4-5 mm diam., 1.8-2.4 x as long as petiole, green, terete; spathe spreading to reflexed, subcoriaceous, green, lanceolate, 10-12 cm long, 1-1.3 cm wide, broadest near the base, inserted at ca. 20° angle on peduncle, acuminate at apex (the acumen with apiculum 4 mm long, inrolled and recurled), prominently decurrent for 2-3 cm at base; spadix "creamy," probably somewhat greenish (post anthesis), cylindroid, sessile, 6-11 cm long, 4 mm diam.; flowers square, ca. 4 mm in both directions; 5-6 flowers visible in principal spiral, 4-5 in alternate spiral; tepals with conspicuous pale raphide cells; lateral tepals 1-2 mm wide, the inner margins broadly rounded, the outer margins 2-sided; anthers 0.8-1 mm long, 1.4-1.8 mm wide, inclined over the pistil; thecae ovoid, slightly divaricate.
