    Known only to northern Perú at 430-800 m in Premontane wet forest transitioning to Tropical (P-wf/T) life zone.
    General Description
    Epiphytic; stems drying dark brown; leaf scars 5-6 mm × 1-1.5 cm; internodes short, drying 1-1.5 cm diam.; cataphylls 4.2-8.2 cm long, drying reddish brown, persisting at upper nodes as almost intact to pale linear fibers near apex, as a reticulum near base, eventually deciduous, acute to acuminate at apex. LEAVES: Petioles 4.5-18.5 cm long, drying 2-3 mm diam., sharply sulcate above, drying light green to brown-yellow; geniculum slightly thicker than petiole, darkened, 7-12 mm long, drying 3-4 mm diam.; blades +/- elliptic, obtuse to rounded or emarginate at apex, cuneate to slightly attenuate at base, 14-22 cm long, averaging 17.9 cm, 4.4-8.9 cm wide, averaging 6.2 cm, 2.5-3.1 times longer than broad, averaging 2.9 times longer, broadest at or slightly above middle, revolute at margins; upper surface drying yellowish green; lower surface brownish green, tinged with gray, glandular-punctate; midrib convex, sometimes flat, sometimes sunken above, drying ca. 0.5-1 mm diam., concolorous, narrowly convex below, drying 1-2 mm wide, concolorous; primary lateral veins 6-7 per side, about 1.2-2.2 cm apart where they arise from the midrib, arsing at a 30°-35° angle from the midrib, straight to the collective vein, concolorous, sometimes drying sunken with an irregular ridge along both margins, sometimes slightly raised above, slightly loop-connected above and below; interprimary veins almost as conspicuous as primary veins, usually one, sometimes two between each primary vein; collective veins arising from near base, concolorous, more prominent than primary veins, 5-11 mm from margin. INFLORESCENCE with peduncle 17.5-26 cm long, averaging 22.8 cm, drying 1-4 mm diam., reddish brown; spathe reflexed-spreading to reflexed, red or purple, sometimes tinged with green, oblong, 2.8-3.5 cm × 5-7 mm, held at a 155°- 180° angle on peduncle, acute or apiculate at apex; spadix purple or dark red, cylindrical, curved away from spathe, spreading to 45°- 90° angle, 7-14.5 cm x 5-9 mm. Flowers ca. 3 × 2 mm, 3-4 visible per spiral, lateral tepals 2 mm wide, margins 2-sided. INFRUCTESCENCES 8.6 cm long, drying 1.6 cm diam., setting berries in lower 1/2 to 3/4 of its length, berries pink.
    Premontane wet forest transitioning to Tropical (P-wf/T) life zone.
    Characterized by small, yellowish green, elliptic blades with rounded to emarginate apices and prominent collective veins. It is very similar to A. tsamajainii, which also has small, yellowish green, elliptic blades, but that species has blades that are narrowly acute or even weakly acuminate at the apex.
