LEAVES: Petiole 3.8-13.7 cm. long; sheath usually more than half total petiole length; blade obliquely ovate to oblong-ovate, 6.6-19.3 cm. long, 3.8-10.2 cm. broad, 1.5-2.4 cm. times longer than broad, shortly acuminate to cuspidate, base rounded, subcordate, obtuse or subacute; pellucid glands sparse to frequent, variable in size, punctate or linear and up to 0.4 cm. long; primary lateral veins forming looping inframarginal veins, at least in upper half of blade. INFLORESCENCES: (3-)4-8(-12), usually 4, inserted on a very short sympodium; all peduncles except the first subtended by lanceolate bracts; peduncle 3-8.5 cm. long. Spathe slightly constricted centrally when closed, green, 2-4 cm. long, 0.5-0.9 cm. in diameter when closed, boat-shaped and gaping at anthesis. Spadix subequal to spathe; staminate part 1.5 cm. long, 0.55 cm. in diameter; pistillate part 0.5-0.6 cm. long, with naked basal stipe 0.2-0.7 cm. long, 0.25 cm. in diameter. Pistils densely congested, subprismatic; stigma sessile, circular, excentric. INFRUCTESCENCE: Berries obovoid to ellipsoid, 0.8-1.1 cm. long, 0.6-0.7 cm. in diameter (when dried), glossy red; mature inflorescences usually with less than 4 berries.
