    General Description
    Epiphyte or terrestrial; stem creeping or erect, to ca. 1m long, slender, brittle; internodes 1-7 cm long; leaf scars 1-1.5 cm diam.; roots 3-5 per node; cataphylls ca. 2.5 cm long, drying light tan, briefly persisting intact, then deciduous. LEAVES persisting at upper 5-6 nodes; petioles terete or obscurely and narrowly sulcate, 8-19 cm long, to 2.5 cm diam.; geniculum ca. 1 cm long; blades narrowly ovate to ovate triangular, subcoriaceous, long-acuminate at apex (the acumen moderately flat and apiculate), lobed at base, 12-22 cm long, 7-13 cm wide, broadest near the base; anterior lobe 11-15 cm long, the sides straight to weakly convex; posterior lobes 5-8 cm long (from apex of sinus to outermost point); sinus parabolic or hippocrepiform, obtuse to round at apex; both surfaces matte, upper surface velvety; the midrib acutely raised above and below, basal veins 4-6 pairs, 3-5 of them coalesced 1.5-4 cm; flat to prominulous above and below; primary lateral veins 6-7 per side, departing midrib at 40-50° degree angle, straight to collective vein, flat above, prominulous below, obscure above, darker than surface below, lesser veins obscure above, visible below; collective vein arising from the first basal vein, 3-10 mm from margin. INFLORESCENCE erect to spreading; peduncle 18-30 cm long, 2-5 mm diam., terete, longer than the petioles; spathe green, moderately thin, oblong-lanceolate, 5-10 cm long, 11-15 mm wide, broadest near the base, acuminate at apex, rounded at the base, inserted at ca. 40° angle on peduncle, the sides sometimes rolled under; stipe 1-3 mm long; spadix green, 5.7-12 cm long, 4-6 mm diam.; flowers rhombic, 2-2.2 mm long (dried), 1.7-1.8 mm wide, 5-7 flowers visible in the principal spiral; tepals semiglossy, drying with a few conspicuous raphide cells clearly visible, lateral tepals 1.2-1.6 mm diam., the inner margin broadly rounded; pistil not emergent; stamens emerging from the base in a relatively complete sequence with the lateral stamens preceding the alternates by only a few spirals; anthers ca. 0.8 mm long, 1 mm wide (dried), held just above the tepals and inclined inward over the pistil; thecae narrowly ovate, scarcely divaricate; pollen white. INFRUCTESCENCE spreading; spathe persistent; spadix to ca. 15 cm long, 2.5 cm diam.; berries dark violet purple, ovoid, exserted and colored before maturity, narrowly rounded at apex; seeds not studied.
