    General Description
    Terrestrial, or caespitose on rocks, sometimes epiphytic; stems 9-30 cm long, 1.5-2.5 cm diam.; roots numerous, dense, spreading to descending, white to green, whitish or brown on drying, ± smooth, thick and short to slender and elongate, weakly tapered at apex, 2-4 mm diam.; cataphylls subcoriaceous, 8-9(16) cm long, acuminate and apiculate at apex, pale green, drying tan, persisting intact, eventually as a reticulum of fibers. LEAVES erect to erect-spreading; petioles (8)16-42 cm long, 5-15 mm diam., broadly triangular, convex adaxially with weak medial ridge, the margins prominently and sharply raised, almost winged, bluntly to sharply angular abaxially, the surface conspicuously pale short-lineate; geniculum slightly thicker and paler than petiole, 1-2 cm long; blades moderately coriaceous, broadly lanceolate to oblong-elliptic to oblanceolate, long-acuminate at apex (the acumen short-apiculate), acute to obtuse at base, (31)40-70(82) cm long, (5)9-28 cm wide, broadest at or above the middle, the margins flat to broadly undulate; upper surface glossy, dark green, lower surface glossy to semiglossy, conspicuously paler; both surfaces matte when dried, green to brown; midrib prominently convex at base, becoming higher than broad toward the apex above, pale short-lineate and paler than surface, prominently and sharply acute-raised below, raised above and below when dried, paler than surface below, same as surface above; primary lateral veins numerous, ca. 20-30 per side, departing midrib at 50-75° angle, straight-ascending, weakly visible above and below when fresh, slightly raised on both surfaces when dried; interprimary veins almost as conspicuous as primary lateral veins; tertiary veins weakly visible when dried; collective vein arising from near the base or in the upper third of the blade, slightly more prominent than primary lateral veins when fresh below, equally as prominent as primary lateral veins when dried, 2-13 mm from margin. INFLORESCENCES erect to spreading, shorter than leaves; peduncle 23-50(62) cm long, 3-7 mm diam., sharply 2-3-ridged, 2-3 x as long as petiole, green heavily tinged with red-violet at base, faintly red-violet toward the apex; spathe reflexed-spreading, subcoriaceous, green tinged with red-violet (B & K yellow-green 6/7.5), linear-lanceolate to lanceolate, 6-10 cm long, 0.4-1.5 cm wide, broadest near the base or in lower third, inserted at 60- 70° angle on peduncle, long-acuminate at apex (the acumen inrolled), acute at base, the margins meeting at 90° angle; spadix brownish purple (B & K red-purple 2/ 10) to dark purple, rarely dark olive-green, cylindroid to weakly tapered, sessile or stipitate 1-2 mm, erect, 5.5-16 cm long, 5-6 mm diam. midway; flowers ± square to 4-lobed, 1.9-2.5 mm long, 2-2.4 mm wide, the sides jaggedly sigmoid; 4-6 flowers visible in principal spiral, 8-10 in alternate spiral; tepals matte to semiglossy, densely papillate; lateral tepals 0.7-1.2 mm wide, the inner margins straight, the outer margins 2-sided, sometimes weakly 4-sided; pistils raised but not emergent, or held slightly above the tepals, green; stigma ellipsoid, 0.4 mm long, brushlike; stamens emerging shortly above the tepals, laterals emerging almost to the apex before alternates emerge; filaments fleshy, translucent or purplish, 0.5-0.8 mm long, 0.4-0.8 mm wide; anthers yellow to purplish, 0.3-0.6 mm long, 0.4-0.7 mm wide, inclined over the pistil; thecae oblong, drying ovoid, scarcely divaricate; pollen white to yellow-orange fading to tan. INFRUCTESCENCE with spathe persisting; spadix 8-22 cmlong, 0.5-1.4 cm diam.; berries reddish to dark purplish violet, ovoid, exserted, acute at apex, drying 4.2-6 mm long, 2- 2.5 mm diam.
    Ecuador on the western slopes of the Andes, and in Nariño, Colombia.
    Premontane wet and premontane moist forest.
