Epiphyte; stems 10-20 cm long, 5-10 mm diam.; roots thin, descending; leaf scars hidden by cataphylls; cataphylls thin, 1-3 cm long, drying tan, weathering into longitudinal fibers. LEAVES erect-spreading; petioles 3.5-19 cm long, 1-2.5 cm diam., sharply and deeply sulcate (the sulcus rounded to flattened with an obscure medial rib near apex), round, dark glands scattered on surface; geniculum 2-15 mm long; blades subcoriaceous, elliptic to lanceolate, sometimes arched along midrib and downturned at apex, long acuminate, obtuse at base, (4-) 7-14 cm long, (1.3-)2.5-8.5 cm wide, broadest at middle or in lower one-fourth of blade; semiglossy on both surfaces, the upper surface with depressed, black glands, the lower surface with reddish brown glands; midrib sharply raised at base above, flat toward middle, sunken at apex, raised below; primary lateral veins (3-)4-7 per side, departing midrib at 40-45° angle, etched into surface above, prominulous below; collective vein arising from base, etched into surface above, raised below, secondary collective vein arising from the base, usually running out to margin near middle or below. INFLORESCENCE erect-spreading; peduncle 11.2-26 cm long, ca. 2 mm diam., sometimes tinged red-violet, equalling or twice as long as petioles; spathe thin, green, tinged red-violet, narrowly ovate, 2-5.2 cm long, 0.9-1.6 cm wide, broadest near middle or just below, inserted at 65° angle on peduncle, becoming reflexed with the margins turned up; stipe 3-17 mm long; spadix deep maroon (B & K Red-purple 2/10-3/10), 1-4.2 cm long, 4-6 mm diam. near base, 2-3 mm diam. near apex; flowers weakly 4-lobed, 2.5-4 mm long, 2.7-3.2 mm wide, the sides straight parallel to spirals, sigmoid perpendicular to spirals, 3-4 flowers visible in the principal spiral, 5-6 flowers visible in the alternate spiral; tepals matte, densely papillate, lateral tepals 1.5-1.7 mm wide, the inner margins straight to convex; pistils emergent, glossy, green, sometimes tinged reddish; stigmas linear, 0.6-0.7 mm long; stamens emerging in a prompt, complete sequence from the base, laterals first, exserted fully above edge of tepals, promptly retracting below edge of tepals, the laterals usually fully retracted before alternates emerge; anthers white, ca. 0.5 mm long, ca. 0.7 mm wide, held flat over edge of pistil before retracting; thecae ovate, not divaricate; pollen white. INFRUCTESCENCE with spadix ca. 4 cm long, 1 cm diam. (to 2.3 cm with berries exserted); berries orange to red, depressed-globose to obovoid, depressed and darker reddish at apex, 4-5 mm long, 5-6 mm diam.; mesocarp fleshy, gelatinous; seeds 2-3(-4), tan, 2-2.2 mm long, 1.5-1.7 mm wide, 1 mm thick.
