    Ranges from Brazil (Acre, Amazonas, Mato Grosso, and Rondônia) to Bolivia (La Paz, Pando, and Santa Cruz), Paraguay (Amambay) and Peru (San Martín).

    General Description
    Epiphytic or epilithic; stem 10-30 cm long, 2.5-6 cm diam.; leaf scars ca. 4 cm wide; roots dense, ascending or descending, whitish green, shortly pubescent, short or elongate, tapered, 4-6 mm diam.; cataphylls coriaceous, 5-20(27) cm Iong, obtuse to acute at apex, drying reddish brown (B & K yellow-red 4/5), persisting as a reticulum of fibers, the epidermis drying thin and flaking off, revealing the thin, reddish brown, hairlike fibers beneath. LEAVES erect to spreading, reported to 2 m long; petioles (7.5)10-40(50) cm long, 4-20 mm diam., U- to C-shaped, narrowly and obtusely sulcate adaxially with the margins blunt, rounded to rarely 1-2-ribbed abaxially, the surface pale-speckled; geniculum thicker than petiole, becoming fissured transversely with age, 0.5-2 cm long; sheath ca. 3 cm long; blades coriaceous, obovate to oblanceolate or elliptic to broadly elliptic, acuminate to obtuse at apex (the acumen inrolled or downturned), acute to attenuate (rarely long-attenuate), or obtuse at base, (24)40-125(200) cm long, (6)20-55(66) cm wide, broadest at or near the middle, the margins prominently and broadly undulate; upper surface matte to semiglossy or weakly glossy, dark green, lower surface matte to weakly glossy, concolorous with the upper surface or slightly paler; midrib flat to angular at base, becoming prominently and convexly raised (almost round-raised, with narrow sulcus along each side) and narrowly angular toward the apex above, prominently thicker than broad to weakly 2-3-ribbed at base, becoming prominently and convexly raised toward the apex below; primary lateral veins (4)7-15 per side, departing midrib at (30)45-65° angle, ascending ± straight to the margin or slightly arcuate-ascending, prominently and convexly raised above and below, more so below; interprimary veins obscure; collective vein arising from near the apex or absent, if present flat to weakly sunken above, flat to weakly raised below, 4-6 mm from margin. INFLORESCENCES erect to erect-spreading; peduncle (2)6-32 cm long, 3-9 mm diam., 0.2-0.3 x as long as petiole, plain green or heavily to slightly tinged with red, purple, or maroon, terete to ribbed abaxially; spathe semi-erect to spreading to reflexed or rolled up, subcoriaceous to coriaceous, violet purple or green tinged with purple, lanceolate to broadly lanceolate, (4)5-26(29) cm long, (0.5)l-3.5 cm wide, broadest near the base, inserted at 40-55° angle on peduncle, acute to long-acuminate at apex (the acumen inrolled), obtuse to acute or sometimes slightly decurrent at base, the margins meeting unequally, thick, rolling down at edges; stipe 1-20 mm long in front, 1-3 mm long in back; spadix green to dull maroon to green tinged with violet to violet-purple, tapered to cylindroid, longer than peduncle, (7)10-46 cm long, 10-20 mm diam. near base, 3-10 mm diam. near apex, broadest at the base; flowers square to rhombic, 1.5-2.5 mm long, 1.1-2.5 mm wide, the sides ± straight to jaggedly sigmoid; (8)10-16(18) flowers visible in principal spiral, 6-10 in alternate spiral; tepals matte, minutely and densely papillate; lateral tepals 0.6-1.2 mm wide, the inner margins straight to convex, the outer margins 2-sided; pistils emergent, weakly raised before the stamens emerge, reddish to dark purple; stigma linear, 0.2-0.6 mm long; stamens emerging in a regular sequence from the base, the laterals preceding the alternates by ca. 5 spirals; filaments holding anthers above the tepals; anthers orange, ca. 0.6-0.8 mm long, 0.8- 0.9 mm wide, inclined over and obscuring the pistil; thecae ellipsoid to obovoid, not divaricate; pollen yellow to orange fading to cream, yeasty-scented. INFRUCTESCENCE erect to pendent; spathe deciduous, leaving a coarse scar; spadix 5-25 cm long, 1-3 cm diam., the apical ? withered, fruits developing in the lower ? only; berries red, oblong-obovoid, slightly rounded at apex (the stigma button-shaped), 8-12 mm long, 3-6 mm diam.; mesocarp juicy, sweet, translucent; seeds 1-2 per berry, brown, densely speckled with translucent dots in rehydrated specimens, oblong to ovoid, 5-6 mm long, 2-3 mm diam., 1.5-2 mm thick, with sticky appendage at the apex (forked in rehydrated specimens).
