    General Description
    Epiphytic; stem short, 1-2.5 cm diam.; roots few, descending, pale greenish, ± smooth, slender, 3-5 mm diam.; cataphylls moderately coriaceous, narrowly lanceolate, 7.5-36 cm long, acute at apex with subapical apiculum, medium green, drying tan, persisting as fine linear fibers. LEAVES spreading to pendent; petioles 1-35 cm long, 3-6 mm diam., terete to subterete, weakly flattened to flattened or rounded adaxially, rounded abaxially, the surface weakly pale-speckled; geniculum thicker and paler than petiole, 0.5-1 cm long; blades subcoriaceous to moderately coriaceous, strap-shaped to narrowly oblong-elliptic, long-acuminate at apex (the acumen weakly apiculate), narrowly acute to obtuse to narrowly rounded at base, (35)83-142 cm long, 3.5-10 cm wide, broadest at or near the middle, the margins weakly undulate; upper surface semiglossy, dark green, lower surface semiglossy to glossy, paler; midrib above acutely raised at base, becoming weakly sunken toward the apex, below prominently higher than broad at base, becoming convexly raised toward the apex and paler than surface; primary lateral veins more than 15 per side, departing midrib at ca. 55° angle, ± straight, obscure to weakly sunken above, somewhat raised and darker than surface below; interprimary veins numerous, almost as conspicuous as primary lateral veins; tertiary veins obscure above, somewhat darker than surface below; reticulate veins prominulous above and below; collective vein arising from near the base, sunken above, weakly raised and darker than surface below, more prominent than primary lateral veins, 3-4 mm from margin. INFLORESCENCES with peduncle to 39 cm long, ca. 9 mm diam., slightly longer than petiole, several-ribbed on drying; spathe spreading, subcoriaceous, pale green, linear-lanceolate, to 29 cm long, ca. 1.5 cm wide, broadest near the base, inserted at 70° angle on peduncle, acuminate at apex (the acumen minutely inrolled), acute at base; spadix brown (fide labels) probably greenish purple, sessile, very narrowly cylindroid, slightly tapered at apex, to 60 cm long, 7-8 mm diam. near base, ca. 4 mm diam. near apex; flowers (dry) rhombic, (2.7)3.4-4.5 mm long, 1.8-2.2 mm wide, the sides jaggedly sigmoid; 7-8 flowers visible in principal spiral, 5-6 in alternate spiral; tepals epunctate, smooth; lateral tepals 2.2-5 mm wide, the inner margins convex; pistils rectangular, green; stigma oblong, ca. 0.7 mm long; filaments retracting on drying. INFRUCTESCENCE to more than 30 cm long, probably with orange berries.
