    General Description
    Stem to 12 cm long, 2-3 cm diam.; leaf scars obscured by cataphylls, 0.8-1 cm high, 1.4-1.7 cm wide; roots numerous, descending to spreading, green, scurfy, weakly pubescent, slender and elongate, 10-1 1 cm long, 3-5 cm diam.; cataphylls subcoriaceous, lanceolate, 3-7 cm lon-g, rounded at apex with a subapical apiculum, green tinged reddish, drying tan to brown (B & K yellow 6/5), persisting as a reticulum of fibers with apex remaining intact, eventually deciduous. LEAVES erect spreading; petioles 5-24 cm long, 3-5 mm diam., D-shaped to somewhat triangular, flattened, sometimes with a medial rib adaxially, the margins sharply raised, rounded to obtusely 1-ribbed abaxially, surface sometimes minutely pale-speckled; geniculum slightly thicker than petiole, ca. 0.7 cm long; blades subcoriaceous, ovate-elliptic, acute at apex (the acumen slightly inrolled), acute to obtuse to usually semirounded to subcordate (sometimes acute to obtuse) at base, (15)19-41 cm long, 6-17 cm wide, broadest at or below the middle, the margins broadly undulate; both surfaces matte to semiglossy, dark to medium green above, somewhat paler below, brown to green on drying; midrib acutely raised at base, becoming flat toward the apex above, prominently convex at base and slightly paler than surface below; primary lateral veins (3)4-8 per side, departing midrib at 45-50° angle, weakly arcuate-ascending, slightly acutely raised above, somewhat convexly raised below; interprimary veins obscure; reticulate veins obscure; collective vein arising from near the base or in the upper ? of blade, weakly sunken above, raised below, 5-10 mm from margin. INFLORESCENCES erect to erect-spreading; peduncle (17)26-36 cm long, (2)3-5 mm diam., 1.5-7.7 x as long as petioles, green tinged with red-violet or purple, terete, sometimes sulcate; spathe reflexed-spreading or sometimes recurled, subcoriaceous to coriaceous, deep red-violet to dark purple (B & K purple 2/7.5 ), oblong-lanceolate, 2-6.2 cm long, 1.2-1.8 cm wide, broadest near the base, inserted at 30-35° angle on peduncle, abruptly acuminate to cuspidate at apex (the acumen inrolled), rounded to obtuse at base, the margins meeting at 180° angle; spadix red-violet to violet-purple (B & K purple 2/7.5), tapered to somewhat cylindroid, sessile, erect, straight, 3.5-9 cm long, 5-9 mm diam. near base, 3-4 mm diam. near apex, broadest at the base flowers f square to rhombic or 4-lobed, 2.2-3.2 mm long, 2.1-3.5 mm wide, the sides straight to smoothly sigmoid, 5-6 flowers visible in principal spiral, 8-9 in alternate spiral; tepals smooth to weakly papillate, matte, weakly punctate; lateral tepals 1-2 mm wide, the inner margins ± straight to convex, the outer margins 2-sided; pistils emergent, dark red-violet; stigma ellipsoid to linear, 0.5-0.7 mm long, brushlike; stamens emerging in a regular sequence from the base, laterals emerging almost to the apex before alternates emerge; filaments exserted, ca. 0.5 mm, 0.6 mm wide; anthers reddish to purple-violet, 0.4-0.8 mm long, 0.6-1 mm wide, inclined over the pistil; thecae ellipsoid to oblong, 0.3 mm wide, not divaricate; pollen cream-yellow (B & K yellow 9/2.5), fading to white. INFRUCTESCENCE with spathe persisting; spadix 4.3 cm long, 0.9 cm diam.; berries deep wine-red, ± ovoid, rounded at apex, 4.5-5 mm long, 3-3.5 mm diam.
    Tropical dry forest life zone.
    Known only from Peru in San Martin Department in the vicinity of Tarapoto.
