LEAVES erect to spreading; petioles 2.5-9.5 cm long, 5-8 mm diam., sharply quadrangular to angularly D-shaped to occasionally subterete, flattened to broadly sulcate adaxially, sharply 1-3-ribbed or sometimes rounded abaxially, the surface minutely pale-speckled; geniculum paler and thicker than petiole, 0.7-l(2) cm long; blades subcoriaceous, oblong-oblanceolate to oblanceolate to oblong-ovate, long-acuminate at apex, acute to obtuse to narrowly rounded at base, 24-83 cm long, 6-26 cm wide, broadest at or above the middle, the margins weakly and broadly undulate; upper surface matte to glossy, medium green, lower surface semiglossy to glossy, paler, drying greenish to greenish brown; midrib flat at base, becoming sharply and narrowly raised toward the apex above, raised and sharply 2-ribbed or prominently convex-raised at base below, becoming convex to flat toward the apex; primary lateral veins 8-16 per side, departing midrib at 40-50° angle, arcuate-ascending, narrowly raised above, less so and darker than surface below; interprimary veins less conspicuous than primary lateral veins; tertiary veins obscure above. darker than surface below; collective vein arising from near the apex or absent, 2-9 mm from margin. INFLORESCENCE erect-spreading to arching-pendent, shorter than or equalling leaves; peduncle 14-48 cm long, 2-6(9)x as long as petioles, green to reddish, weakly striate, terete to subterete, faintly ribbed; spathe spreading to reflexed, subcoriaceous, light green, sometimes tinged with purple, narrowly lanceolate, 5.5-9(13.5) cm long, 0.7-1.3(2) cm wide, broadest near base, inserted at 45-90° angle on peduncle, long-acuminate at apex (the acumen inrolled), obtuse to subcordate at base; spadix green to green tinged with red to pale reddish to reddish violet or purplish, oblong-cylindroid to long-tapered, 5-15 cm long, 4-10 mm diam. near base, 2.5-4 mm diam. near apex; flowers rhombic to weakly 4-lobed, 1.4-2.8 mm long, 1.8-3 mm wide, the sides smooth to jaggedly sigmoid; 5-9 flowers visible in principal spiral, 5-12 in alternate spiral; tepals matte to weakly glossy, minutely and densely papillate and pale punctate; lateral tepals 1.2-1.5 mm wide, the inner margins straight to broadly convex, somewhat erose, the outer margins 2-4-sided; pistils prominently to weakly raised, weakly glossy, papillate, green to white; stigma 0.4-0.5 mm long, brushlike; stamens emerging in slow progression from the base in a complete sequence, the laterals preceding the alternates by 6-34 spirals, the 3rd stamen preceding the 4th by 1-12 spirals, arranged in a circle around pistil; filaments translucent, 0.5 mm long, 0.4 mm wide; anthers yellow to white, 0.5-0.6 mm long, 0.5-0.8 mm wide; thecae broadly to oblong-ovoid, not divaricate; pollen yellow fading to white, sweet-scented. INFRUCTESCENCE spreading; spadix to 26 cm long, with berries scattered throughout; berries cream to greenish yellow or pale orange, oblong-ovoid to ovoid-ellipsoid, acute at apex, 4-7.8 mm long, 3.3-4.2 mm diam.; pericarp thickened; seeds 2 per berry, pale yellow with numerous pale, granular raphide cells on the surface, oblong-ovoid, slightly or not at all flattened, 2.6-3 mm long, 1.5-1.8 mm diam., 1-1.3 mm thick, with a transparent, gelatinous, sticky appendage.
Southern Costa Rica and Panama, occurring principally on the Caribbean slope. It also occurs on the Pacific slope in the Fortuna area of Chiriquí Province in Panama.
Wetter parts of tropical moist forest, as well as in tropical wet, premontane wet, and lower montane wet forest.
