SUMMARY
Epiphytic or terrestrial; stems to 25 cm long, 1-2 cm diam.; leaf scars obscured by persisting cataphylls; roots long, thin; cataphylls coriaceous, 12-20 cm long; drying reddish brown (B & K Yellow-red 4/7.5), persisting intact. LEAVES erect to erect-spreading; petioles (17-)25-62 cm long, ca. 4 mm diam., terete; geniculum 2-2.5 cm long; blades ovate to ovate triangular, moderately thick, long-acuminate at apex, deeply lobed at base, 21-36 cm long, 11.5-20 cm wide, broadest at point of petiole attachment or just above; anterior lobe 13.5-27 cm long, the margins rounded; posterior lobes 6-11.5 cm long, from apex of sinus to outermost point; the sinus hippocrepiform, rounded at apex; upper surface semiglossy with conspicuous raphide cells, lower surface drying matte; midrib raised above and below; basal veins 4-5 pairs, the first, sometimes second free to the base, the second to fifth coalesced 0.6-4.5 cm, raised above, prominently raised below; posterior rib naked, the inner margin weakly turned up; primary lateral veins 3-5 per side, departing the midrib at a 45-60° angle, sunken above, raised below, drying scarcely more conspicuous than lesser veins on upper surface, more prominent below, lesser veins visible on drying; collective arising from the first or second basal vein or sometimes from the third, 5-8 mm from margin, sunken above, raised below. INFLORESCENCE more or less erect, much shorter than leaves, peduncle 4÷30 cm long, 4÷6 mm diam., one-fifth to two-thirds as long as petioles; spathe subcoriaceous, green, ovate-elliptic, 3-5 cm long, 1.5-4.5 cm wide, broadest near the middle, rounded at apex, rounded to more or less obtuse at base, held erect at anthesis; stipe to 4 mm long; spadix white, becoming red- violet, short, cylindroid (scarcely tapered) to globose, 2-5.3 cm long, 7.5-20 mm diam. midway, flowers 4-lobed, ca. 1.5 mm long, 2.5 mm wide, the sides straight to weakly sigmoid; ca. 8 flowers visible in the principal spiral, ca. 12 flowers visible in the alternate spiral; tepals glossy, the lateral tepals ca. 0.6 mm wide, the inner margin rounded, the outer margin 3-4-sided; pistils raised, emergent; stamens held over and obscuring pistil; anthers white, 0.8 mm wide (dry). INFRUCTESCENCE erect-spreading; spathe reflexed; spadix 4-6 cm long, ca. 3.5 cm diam.; berries orange to red-orange, oblong-elliptic, 1.3-1.5 cm long, 5-5.5 mm diam., mesocarp white, gelatinous, with raphide cells; seeds 1-2, pale green to yellow, 4.3-4.5 mm long, 2.3-2.8 mm wide, appendaged at apex, surrounded by a clear mucilaginous sac.
