    Terrestrial; internodes shorter than broad, drying 3-3.5 cm diam.; cataphylls 9.5- 15 cm long, unribbed, drying dark red-brown, persisting at upper internodes as dense, coarse, dark, mostly longitudinal fibers. LEAVES: Petioles 71- 74 cm long, drying 5-7 mm diam., sulcate at least near base, drying gray, sometimes pale grayish green near base; geniculum 1.8-2.5 x 5-9 cm, concolorous or sometimes brown-red, sometimes minutely ridged or wrinkled; blades cordate with margins broadly convex; somewhat narrowly acuminate at apex (acumen 1.3-2.5 cm long), 59-61.5 × 39-43 cm, 1.3-1.5 times longer than broad, ca. 0.8 times the length of the petiole, drying gray-green above, reddish gray below; anterior lobe 42.5-45 × 19-23 cm at midpoint; posterior lobe 20-22 × 14-15 cm; sinus broadly spathulate, 15-16 cm deep; midrib narrowly rounded, drying 1-2 mm wide, slightly paler above, thicker than broad, sometimes acute, concolorous to slightly darker below; primary lateral veins 6-8 per side, 2-5 cm apart, departing midrib at a (40°-) 50°-60° angle, +/- straight or slightly arching to a collective vein, somewhat prominent above, prominent below; basal veins 7-9 per side, 1st pair free or almost free to base, 6th and 7th coalesced to 5.5-6.5 cm; posterior rib naked 5.5-7.5 cm along sinus; collective veins sometimes arising from one of the lower basal veins, sometimes from about the middle of the blade, somewhat less prominent than primary lateral veins, 3-7 mm from margin. INFLORESCENCE peduncle 28-31 cm long, drying ca. 5 mm diam., drying grayish red or yellow-brown; spathe erect, green, lanceolate, 10.5-15.5 (-19) × 2-2.4 (-5.3) cm; spadix dark purple, curved away from spathe, slightly stipitate (stipe 5-6 mm long), 9.5-16 cm long, drying 6-7 mm diam.
