    General Description
    Epiphytic or epilithic; stem to ca. 25 cm long, ca. 2.5 cm diam.; roots dense, spreading to erect-ascending, pale greenish white, ca. 4 cm long, 3- 5 mm diam.; cataphylls narrowly coriaceous to subcoriaceous to nearly membranous, lanceolate, sometimes hooked in the upper part, weakly l-ribbed near apex, 11-18 cm long, acuminate at apex with a subapical apiculum ca. 6 mm long at apex, drying dark brown to reddish brown (B & K yellow-red 3/ l0), persisting ± intact, ultimately deciduous. LEAVES erect; petioles (2)8-16 cm long, 10-1 5 mm diam., erect, D-shaped to ± quadrangular, shallowly sulcate adaxially, with thin, erect margins, prominently and unevenly 3-8-ribbed abaxially; geniculum somewhat thicker and slightly paler than petiole, 1-2 cm long; blades coriaceous to subcoriaceous, usually oblanceolate to ± elliptic, sometimes narrowly obovate, acute at apex, narrowly acute to narrowly rounded (less often rounded-subtruncate) at base, (30)40- 110 cm long, (13)18-36 cm wide, broadest above the middle, the margins moderately undulate; both surfaces semiglossy, upper surface medium green (B & K yellow-green 6/7.5), drying greenish to grayish brown; lower surface moderately to conspicuously paler greenish to reddish brown (B & K yellow-green 7/10); midrib flat with medial rib at base, becoming broadly acute toward the apex below, drying reddish brown; primary lateral veins 10-17 per side, departing midrib at 50-65° angle, ascending ± straight or slightly arcuate to near the margin, prominently and convexly raised above, less so below; tertiary veins scarcely visible above, slightly darker than surface below, prominulous and raised on both surfaces when dried; reticulate veins not visible below when fresh, weakly visible when dried; collective vein arising from near the apex, less prominent than primary lateral veins, 5-10 mm from margin. INFLORESCENCES arching-erect to spreading; peduncle 30-75 cm long, 5-9 mm diam., 2-4.4(11) x as long as petiole, green, sometimes purple-speckled, usually subterete, sometimes 1-ribbed; spathe reflexed, subcoriaceous, green tinged with violet-purple, narrowly oblong-ovate or oblong-elliptic 5.5-14 cm long, 1.4-3.5 cm wide, inserted at 10-70° angle on peduncle, gradually to abruptly acuminate at apex, acute to obtuse at base; spadix dark purple-violet (B & K red-purple 2/5), sometimes green tinged purple-violet, sessile or subsessile, subcylindroid or weakly tapered, 5.5-16 cm long, 7-9(12) mm diam. near base, 5-7(9) mm diam. near apex; flowers rhombic, 2-3.3 mm long, 2.4-3.5 mm wide, the sides ± straight parallel to spiral, sigmoid perpendicular to spiral; 5-9 flowers visible in principal spiral, (3)6- 10 in alternate spiral; tepals matte to semiglossy weakly to conspicuously and densely punctate, forming large nectar droplets on surface at anthesis; lateral tepals 2-2.3 mm wide, the inner margins straight; pistils weakly emergent, green tinged with violet-purple; stigma broadly ellipsoid, 0.5-0.6 mm long, brush-like, droplets appearing 5-8 days before stamens emerge; stamens emerging rapidly in a scattered pattern throughout, sometimes those at apex emerging first, held barely above level of the tepals, sometimes erect when dried; anthers purplish brown to purple-violet, 0.8- 1 mm long, 0.8-1.1 mm wide, in a tight cluster obscuring pistil; thecae oblong-ellipsoid, ± divaricate; pollen purplish (B & K purple 6/10). INFRUCTESCENCE pendent; spathe persisting at least in early fruit; spadix to 30 cm long, 2.5 cm diam.; berries red, obovoid, 7-8 mm long, ca. 5 mm diam.; pericarp with numerous raphide cells; mesocarp transparent, gelatinous; seeds 2 per berry, white, oblong-ellipsoid, ca. 4 mm long, ca. 1.3 mm diam.
    This species is distinguished by its short, cylindrical, violet-purple spadix held erect at anthesis, by its tendency to form globular droplets on the tepals, by its purplish pollen, its bright red berries, and by the petioles, which are broadly sulcate adaxially and usually prominently several-ribbed abaxially.
