Terrestrial or hemiepiphytic; stems short, internodes (1)3-6 cm diam.; cataphylls 19-30 cm, drying reddish brown, weathering into fibers, persisting at upper nodes. LEAVES with petioles erect-spreading, 75-130 cm long, equal to or up to 1.5 times longer than blade, 10-15 mm diam., square or sometimes D-shaped in cross section, with thin, brittle, spreading wings at corners, medium green and semiglossy; geniculum 2 cm long, square in cross-section with winged margins, undulate; blades pendent, ovate, sagittate, narrowly acuminate with acumen slightly down-turned, prominently and deeply lobed at base, 72-120 cm long, 30-70 cm wide, 1.5-3 times longer than broad, broadest at point of petiole attachment, semiglossy and dark green above, weakly glossy to matte and slightly paler below, both surfaces drying brown (B&K: yellow 4/5; RHS #165 A: Beech Brown); anterior lobe 60-90 cm long, 20-35 cm wide, nearly 3 times longer than broad, margins nearly straight, sometimes undulate; posterior lobes 25-30 cm long, 20-35 cm wide, nearly as broad as long, rounded at apex, sinus spathulate to obovate, 15-30 cm deep; midrib slightly raised above, quadrangular to round-raised below with thin, spreading wings at corners towards base, drying with an acute medial rib; basal veins 7-9 pairs, slightly raised in deep valleys above, narrowly acute to knife edged below, ca. the first 5 branching from posterior rib in 2-3 cm increments, the remainder branching from the same point where naked portion of rib ends, posterior ribs naked for 8-15 cm; primary lateral veins 23-28 per side, weakly raised in deep valleys above, acutely raised below, departing midrib at 55-60° angle, ascending nearly straight to collective veins; collective veins arising from the 4th-6th basal veins, prominently raised below; tertiary veins prominently raised and darker than surface below. INFLORESCENCE with peduncle spreading, 40-65 cm long, ca. 1 cm wide, terete to square in cross-section, sometimes with thin, spreading wings; spathe white, lanceolate, 9-15 cm long, 1.5-2.5 cm wide, reflexed, inserted on peduncle at 60° angle, gradually acuminate at apex, the margins meeting acutely at base; spadix sessile to stipitate, stipe 3-8 mm, dark violet-purple or maroon, cylindrical, (14)25-30 cm long, 1 cm wide, erect, held at ca. 90° angle to peduncle; flowers rhombic, 12-14 visible in principal spiral, 2 mm long, 1.6 mm wide, the sides straight, lateral tepals 0.6 mm wide, 1.3 mm long, inner margins convex; pistils weakly exserted. INFRUCTESCENCE with purple berries which are white at the base.
