    General Description
    Terrestrial to 1 m tall; stems 2.5-3 cm diam.; internodes very short; leaf scars to 2 cm wide; roots few, moderately thin, descending; cataphylls coriaceous, sometimes tinged with purple, 5-9 cm long, emarginate and long-apiculate at apex, drying dark tan (B & K Yellow 6/7.5), weathering into longitudinal fibers and persisting. LEAVES with petioles arching, subterete, sometimes narrowly and bluntly sulcate, or weakly flattened adaxially, 12-46 cm long; geniculum 0.7-1.1 cm long; blades medium thick, narrowly ovate to ovate-triangular, gradually long-acuminate at apex, deeply lobed at base, 20-43 cm long, 12-27 cm wide, broadest at base or midway between base and point of petiole attachment, the margin broadly undulate; anterior lobe 15-32 cm long, margin broadly convex, posterior lobes 4-14.5 cm long; sinus hippocrepiform to spathulate or parabolic, rounded to acute at apex; both surfaces semiglossy; the midrib convexly raised above, raised and conspicuously more acute below; basal veins 4-6 pairs, prominulous above, and below, third to sixth coalesced 2-3.5 cm, posterior rib straight to weakly curved, almost completely naked, the outer margin turned conspicuously upward; primary lateral veins 3-5 per side, departing midrib at ca. 50° angle, straight to weakly arching to collective vein, sunken above, flat to prominulous below; lesser veins visible, ± flat above and below; collective vein arising from the first basal vein, sunken above, raised below, 8-12 mm from the margin. INFLORESCENCE usually longer than leaves, spreading to pendent; peduncle 25-84 cm long, 2.5-3.5 mm diam., terete, at least twice as long as petioles; spathe coriaceous, green, sometimes tinged with violet-purple, oblong-lanceolate to narrowly ovate-triangular, 5.5-13 cm long, 1.5-3.3 cm wide, gradually long-acuminate at apex, narrowly inrolled to 2.5 cm long, rounded to subcordate at base, inserted at 45°-60° angle on peduncle; spadix green turning dark violet-purple to brownish at anthesis, 4.8-12.2 cm long, 5-12 mm diam. at base, 3-6 mm diam. at apex; flowers rhombic to sub-4-lobed, 3.3-4.1 mm in both directions, the sides straight to gradually to jaggedly sigmoid; 6-7 flowers visible in the principal spiral, 6-8 flowers visible in the alternate spiral; tepals matte, weakly punctate, minutely papillate with scattered droplets, lateral tepals 2-2.5 mm wide, the inner margins broadly convex; pistils green, weakly exserted just before anthesis; stigma elliptic, conspicuously raised, large stigma drop apparent shortly before stamens emerge; stamens emerging from base in a regular pattern, the laterals first, soon followed by alternates, complete in basal one quarter before the laterals emerge just above midway; anthers cream, held in non-contiguous circle around pistil, ca. 1 mm long, 1-1.1 mm wide; thecae ovoid, slightly divaricate; pollen cream. INFRUCTESCENCE spreading to pendent; the spathe persistent; spadix 11-13 cm long, 1.7-2 cm diam., berries usually developing in basal one half to two thirds; berries bright orange, ± globose, usually with 4 radial ridges, the apex broadly rounded to nearly truncate; mesocarp juicy, somewhat pulpy, orange with numerous raphide cells; seeds 2, obovoid, 6-7.5 mm long, 4.5-6 mm wide, 3-4 mm thick, depressed at apex.
    It occurs in wet cloud forests on usually steep slopes.
