    Epiphyte, sometimes secondarily terrestrial; stems 18-30 cm long, 1-1.5 cm diam., branching, creeping, elongate; internodes 0.8-2 cm long; roots numerous, dense, 3-4 mm thick, directed downward; cataphylls thin, 6-11 cm long, gradually long-acuminate at apex (the acumen 2-4 cm long and inrolled) drying tan, persisting, di-lacerating. LEAVES spreading; petioles 5-22 cm long, 4-7.5 mm diam., narrowly, deeply, and acutely sulcate, rounded abaxially; geniculum 1.5-2 cm long; blades lanceolate to oblong-lanceolate, thin to medium thick, gradually long-acuminate at apex (the acumen acute or very minutely inrolled), acute to attenuate at base, 13-30 cm long, 4-7.5 cm wide, broadest slightly below the middle; the upper surface glossy, dulling with age, lower surface glossy or semiglossy; midrib raised, triangular above, diminishing to ward apex, convexly raised below; primary lateral veins 11-16 per side, departing midrib at 55°-65° angle, sunken above, raised below, straight to arcuate-ascending, loop-connecting; collective vein arising from the base or the first or second pair of lateral veins, 3-4 mm from margin, sunken above, raised below. INFLORESCENCE erect-spreading; shorter to longer than leaves; peduncles 20-40 cm long, 1.5-3 mm diam., terete, equalling or longer than petioles; spathe medium green (B & K Yellow-green 5/ 10), linear-lanceolate, 4.5-8.5 cm long, 4-9 mm wide, broadest near the base, long-acuminalc at apex, acute at base inserted at a 50°-70° angle on peduncle; stipe 3 mm long in front, 1 mm long in back, 4-5 mm diam., or spadix sessile; spadix greenish-yellow at base, paler at apex (B & K Yellow-green 8/5 to 6/7.5), 4.5-10 cm long, 3-6 mm diam. at base, 2-4 mm diam. at apex; flowers rhombic, 1.7-2.8 mm wide in both directions, the sides sigmoid; 5-6 flowers visible in the principal spiral, 5-10 flowers visible in the alternate spiral; tepals glossy to matte, papillate, green to greenish-yellow, brown in fruit, the lateral tepals 0.8-1 mm wide, the inner margin thin, turned up against pistil; pistils slightly emergent, green, at first covered by tepals and flat, rapidly emergent into a pointed mound; stigma 0.3-0.5 mm long, ellipsoid, brushlike, white, exserted. small droplet persisting for 1-2 days before stamens emerge, dry and gray when stamens emerge, usually not emerging in the apical half to third of spadix; stamens emerging rapidly from the base in a regular sequence, laterals first followed by alternates, held at the side of pistil, sometimes contiguous; anthers pale yellow, 0.2-0.3 mm long, ca. 0.4 mm wide; thecae ellipsoid, prominently divaricate, opening bowl-shaped; pollen orange-yellow, fading creamy white; strong sweet aroma present when stigma droplets appear and continuing while pollen is fresh. INFRUCTESCENCE spreading-pendent; the spathe green, intact; spadix 5-9 cm long; berries obovoid to depressed-globose, almost flat at apex, pale yellow-green, to 5 mm long; mesocarp watery, clear, sweet; seeds 2, pale green, flattened, to 2.8 mm long and 2.5 mm wide, each enveloped in a clear, gelatinous substance to 4 mm long.
