Leaves with petiole 45–66 cm long, subterete, prominently sulcate adaxially and sometimes with a medial rib adaxially, usually prominently ribbed on drying with up to 9 ribs circumferentially (sometimes stronger ribs alternating with weaker ribs), drying matte, grey-brown; geniculum 1 cm long, remote; blade narrowly oblong-oblanceolate, 71 – 78 × 26 – 34 cm (averaging 74.5 × 30 cm), 2.2 – 2.7 × as long as wide, 2.3 × longer than petiole, gradually acuminate at the apex, moderately bicolorous, dark green and semiglossy above, slightly paler and slightly more glossy below; midrib broadly convex, concolorous above, multi-ribbed, quadrangular and slightly darker brown below; primary lateral veins 7 – 10 pairs, arising at c. 45° angle, narrowly rounded on both surfaces, drying ± concolorous and sometime with acute ridges above, narrowly rounded, darker and often with fine ridges below; tertiary veins drying prominently raised on both surfaces; collective veins arising from one of the primary lateral veins from below the middle to the upper 2/3 of the blade, drying raised on both surfaces. Inflorescence erect, shorter than leaf; peduncle 46 – 92 cm long, 5.5 × longer than spathe, drying reddish brown; spathe 8.4 – 14 × 1 – 1.4 cm, lanceolate, green, drying light brown, matte; spadix 9 – 16.6 cm long, 6 – 9 mm diam., violet-purple, drying purplish brown, sessile or weakly stipitate to 3 mm.
