    General Description
    Terrestrial, deeply rooted among rocks, less frequently epipetric in thin soil on rocks; stems 1-2 cm diam.; leaf scars 1.7 cm wide; cataphylls subcoriaceous, 3-4 cm long, obtuse at apex with subapical apiculum, pale red-violet with pale green speckles, drying brown (B & K Yellow 5/2.5), splitting and persisting. LEAVES erect to spreading; petioles 7-16 cm long, 4-6 mm diam., terete, green or pale red-violet with green speckles; geniculum 1-1.5 cm long; blades ovate, moderately coriaceous, abruptly to gradually acuminate at apex, deeply lobed at base, 11-25.5 cm long, 6.5-17 cm wide, broadest at middle or just below, the margin flat, drying conspicuously undulate; anterior lobe 6.5-18 cm long, the margins convex; posterior lobes 2.5-9 cm long; sinus spathulate to obovate, the lobes sometimes overlapping, acute at apex; upper surface matte, velvety, dark green, lower surface paler, matte; midrib convexly raised, diminishing at apex above, raised below; primary lateral veins 3-5 per side, raised above, flat below; interprimary veins conspicuous; basal veins 4-5 pairs, free to base or sometimes the third to fourth veins coalesced, the first curving to apex, the second to fourth arcuate-ascending to margin, loop-connecting; collective vein arising from first basal vein; all veins clearly outlined by white or greenish white area. INFLORESCENCE erect-spreading, longer than leaves; peduncles 16-38 cm long, 2-4 mm diam., terete, green tinged with red-violet, longer than petioles; spathe chartaceous, pale green tinged with violet-purple near margins (B & K Yellow-green 6/7.5), lanceolate, 3.7-6.5 cm long, 1-1.5 cm wide, broadest at base, narrowly acuminate at apex, obtuse at base, inserted at 40°-70° angle on peduncle; stipe to 5 mm long in front, to 2 mm long in back; spadix green, tinged with violet-purple sometimes appearing brown (B & K Yellow-green 5/5 to Yellow 4/10), 4.7-7.5 cm long, 4-7 mm diam. at base, 3-3.5 mm diam. at apex; flowers sub-4-lobed to square, 3.8-5 mm long, 3.2-5 mm wide, the sides jaggedly sigmoid; 3-4 flowers visible in the principal spiral, 5-8 flowers visible in the alternate spiral; tepals matte, papillate, densely and conspicuously punctate, large droplets visible as stamens emerge, lateral tepals 2.8-3.1 mm wide, the inner margin weakly concave; the pistils weakly emergent usually as soon as spathe opens, green; stigma elliptic, 0.6-1 mm long, brushlike, exserted with large droplets 2-3 days before stamens emerge; stamens emerging rapidly from base on flattened, translucent filaments 1 mm long, 1.5 mm wide, lateral stamens emergent to midway before alternates appear, retracting and held just above tepals; anthers yellow, 0.4-0.8 mm long, 0.7-1.5 mm wide, thecae elliptic, not divaricate, pollen cream fading to white. INFRUCTESCENCE with bright orange, subglobose berries, ca. 1.5 mm long; mesocarp mealy, seeds not seen.
