    General Description
    Terrestrial or rarely epiphytic; internodes usually less than 5 mm long at lower internodes, sometimes up to 1.5 cm at uppermost internodes, drying 1.1-2.8 cm diam., tan; cataphylls 6-11 (-18) cm long, unribbed or weakly 1-ribbed, drying reddish or greenish gray, lanceolate, persisting intact at upper internodes only, then quickly deciduous or remaining as small fragments. LEAVES: Petioles (25.5-) 38.5-82 cm long (averaging 56 cm), drying 3-5 mm diam., drying deeply grooved, gray, faintly tinged with red or green, sometimes sulcate adaxially; geniculum terete (or at least not grooved), often slightly darkened, 1.5-2.5 cm long, drying 3-4 mm diam., smooth; blades +/- ovate-cordate, gradually acuminate to acute at apex, often apiculate, lobed at base, 32.5-54 cm long (averaging 41.2 cm), 22-33 cm wide (averaging 25.3 cm), 1.5-1.7 times longer than wide, 0.6-1 (-1.3) times the length of the petiole, usually broadest at or just above the point of petiole attachment, drying dark gray-green, occasionally faintly tinged with red above, paler, light gray-green below; anterior lobe 25-39 cm long, 14-27 cm wide at midpoint, 1.3-2 times longer than wide, 1.9-2.3 (-2.6) times longer than posterior lobe, broadest near base, convex to straight along margins; posterior lobes rounded, 11-17 × 6- 11 cm, sometimes broadest at base, sometimes broadest near middle, directed more or less inward; sinus hippocrepiform to spathulate, 7.5-15 cm deep; midrib almost flat to broadly convex, drying 1-2 mm wide, concolorous or sometimes slightly paler than surface above, narrowly convex, thicker than broad, prominently raised, white, conspicuously paler than surface, sometimes ridged, speckled below; primary lateral veins 7-10 per side, 1-3.5(-4.5) cm apart, departing midrib at a 35°-50° angle, concolorous to slightly paler than surface, convex to narrowly rounded above, much paler, raised below, curving towards margins; basal veins 5-7 per side, with first and second free to base, 4th and higher coalesced 2.5-4 cm, conspicuously paler below; posterior rib naked 2.5-4.5 cm along sinus; collective veins not conspicuous (or if there is one, it arises from the middle of the blade and is then less than 1 mm form margin). INFLORESCENCE with peduncle 20-48.5 cm long, drying 3-4 mm wide, gray to grayish red; spathe usually spreading to reflexed; sometimes green, lanceolate to oblong, 8-12.5 × 0.8-2.1 cm, generally acute at apex; spadix purple or brown, often somewhat tapered, sometimes slightly stipitate (with stipe less than 2 mm), often curved, 5.5-12.5 cm long, drying 4-7 mm diam., 9.7-25 times longer than wide (usually more than 15 times longer than wide). Flowers 2-2.6 × 1.8-1.9 mm, 5-6 visible per spiral; lateral tepals 1-1.2 mm wide, 3-sided, shield shaped.
    It is characterized by greenish-gray drying blades, very pale venation on the lower blade surfaces, and posterior lobes directed more or less inward. The species is similar to A. kusuense, in the shape and color of the blade and venation, but A. kusuense has cataphylls that weather to fibers instead of persisting intact, much longer petioles, wider blades, and spadices with more flowers visible per spiral.
    Premontane wet forest transition to Tropical (P-wf/T), and likely Tropical wet forest (T-wf) as well.
    Known only from northern Perú in the Río Cenepa-Río Santiago region.
