Epiphyte or terrestrial, 30-90 cm tall; stems 1-1.5 cm diam.; the internodes very short; roots short, 3.5 mm diam.; leaf scars obscured by persisting cataphylls; cataphylls 4-7 cm long, drying reddish-brown weathering into coarse fibers. LEAVES spreading; petioles 15-45 cm long, 3-5 mm diam., obscurely and narrowly flattened adaxially sometimes with a faint medial rib; geniculum ca. 1.5 cm long, tinged purplish; blades subcoriaceous, lanceolate to ovate-lanceolate or oblong-elliptic, 20-30(50) cm long, 4-12 cm wide, long-acuminate at apex, cuneate at base; both surfaces semiglossy with black glandular punctations, more conspicuously so on lower surface; midrib narrowly and convexly raised above, becoming more acute at apex, prominently raised below; the primary lateral veins 15-25 per side, departing the midrib at 35° angle, sunken in valleys above, raised below; lesser veins obscure; collective vein arising from near the base, relatively straight, extending to the apex, 5-15 mm from the margin. INFLORESCENCE ± erect, shorter than leaves; peduncle 26-60 cm long; spathe green, oblong-lanceolate, 4.3-8.5 cm long, 0.8-1.9 cm wide, broadest at base, abruptly cuspidate at apex; spadix gray- or greenish-white, 4.5-9.5 cm long, 5-7 mm diam. at base, 4-5 mm diam. at apex; flowers rhombic to 4-lobed, 3-3.3 mm long, 3.3-3.6 mm wide, the sides straight to broadly sigmoid; ca. 5 flowers visible in the principal spiral, ca. 8 flowers visible in the alternate spiral; tepals glossy, smooth, the lateral tepals ca. 2 mm long, the inner margin convex; the pistil emergent; stigma green, elliptic, ca. 3 mm long; stamens emerging 1 or 2 at a time, exserted on fleshy, flattened filaments; anthers while, held just above tepals, 0.5-0.8 mm in both directions; thecae not divaricate; pollen white. INFRUCTESCENCE pendent; spadix to 15 cm long; berries violet-purple, ovoid to globose, ca. 3-5 mm wide; mesocarp pulpy; seeds white, broadly ellipsoid, to 4 mm long, 3 mm wide, 2 mm thick, flattened.
