SUMMARY
Epiphyte; stems 5-10 mm diam., internodes short (at least near apex); leaf scars inconspicuous; roots few; cataphylls moderately thin, 11-12.5 cm long, drying intact, faintly reddish brown, the bases of the fibers persisting. LEAVES with petioles 11-30 cm long, ca. 4 mm diam., sulcate adaxially; geniculum ca. 1 cm long; blades drying greenish, moderately thin, weakly bullate, ovate-triangular to narrowly triangular or sub-3-lobed, narrowly acuminate at apex (the acumen flat), prominently lobed at base, to 32 cm long, 6.7-22 cm wide, broadest at the base; anterior lobe 22-30 cm long, the margins slightly convex to concave; sinus arcuate with a decurrent petiole, broader than deep, ca. 3 cm deep; both surfaces drying conspicuously veiny, matte to semiglossy above, semiglossy below; midrib raised on both surfaces; basal veins 6 or 7 pairs, the uppermost free, the third and higher coalesced 1.5-2.5 cm, the posterior rib weakly curved, naked more than 1 cm; primary lateral veins ca. 15 per side, departing midrib at 40-50° angle, weakly arcuate to the collective vein; interprimary and secondary veins drying scarcely less prominent than the primary lateral veins; tertiary and reticulate veins drying prominulous below; collective veins arising from the lowermost basal veins, 1-6 mm from the margin. INFLORESCENCE erect, shorter than the leaves; peduncle 16-22 cm long, terete; spathe moderately thin, light green to pinkish green, lanceolate, 6-11 cm long, 1.2 cm wide, acuminate at apex, acute at the base, weakly decurrent, inserted at 45° angle on peduncle; spadix sessile, yellow to green, gradually tapered, 6-12 cm long, 3.5-5 mm diam. at the base, 2-2.5 mm diam. (dry) near the apex; flowers rhombic to sub-4-lobed, 1.8-2 mm long, about as broad as long, 6-11 flowers visible in the principal spiral; tepals weakly glossy, densely punctate, with raphide cells on drying, the lateral tepals 1-1.4 mm wide, the inner margin broadly rounded, the outer margin with the 2 sides convex; pistil not emergent; stamens weakly emergent, anthers 4-5 mm long, 5-6 mm wide; thecae ovate, moderately divergent. INFRUCTESCENCE not seen.
