    Distribution
    Known only from a region of premontane wet forest-basal belt transition in extreme southwestern Costa Rica. It will no doubt be found elsewhere in Costa Rica and Panama on the Atlantic slope.
    General Description
    Terrestrial, to 1 or more m tall; stem usually less than 50 cm long, 2.5-5 cm diam.; leaf scars conspicuous, 2-4 cm wide; roots few, descending, green, with flaky or scaly epidermis when dried, often short and blunt, ca. 5 mm diam.; cataphylls coriaceous, hooked, faintly 1-ribbed at apex, 9-12 cm long, apiculate at apex, dark purple to maroon (B & K purple 2/7.5), drying brown tinged with reddish purple, persisting intact or semi-intact, eventually deciduous. LEAVES erect to spreading; petioles 40-150 cm long, 5-10 mm diam., stiff and firm, bluntly D-shaped to subterete, weakly and shallowly sulcate to flattened adaxially, rounded (sometimes with few faint ridges) abaxially, the surface green, sometimes with dark purple tinge spreading from the base; geniculum thicker and paler than petiole, 2-3 cm long; blades subcoriaceous, ovate, gradually acuminate at apex (the acumen downturned, long-apiculate), cordate at base, 44-100 cm long, 33-50 cm wide, broadest below or near the middle, the margins shallowly undulate, flat to revolute; anterior lobe 32-80 cm long, the posterior lobes 12-21 cm long, directed inward, rounded at apex; sinus usually narrowly triangular to closed, sometimes with overlapping lobes; upper surface matte to semiglossy, medium green, lower surface semiglossy, slightly paler; midrib above acutely raised at base, becoming sharply and narrowly raised toward the apex and paler than surface, below convexly raised at base, becoming sharply acute toward the apex; basal veins 5-9 pairs, not coalesced, sharply and narrowly raised above, less so below; primary lateral veins 9-20 per side, departing midrib at 35-50° angle, slightly arcuate-ascending, faintly loop-connecting, sharply raised above, less prominently and paler than surfaces below; interprimary veins few, narrowly raised above and below, paler than surface above; tertiary veins flat to weakly sunken above, somewhat raised below, paler than surface above and below; reticulate veins scarcely visible above, scarcely raised below, prominulous when dried on both surfaces; collective vein arising from 2nd basal vein, slightly sunken above, slightly raised below, obscure above when dried, slightly raised and paler than surface below, 2-6 mm from margin. INFLORESCENCES erect, much shorter than leaves; peduncle sometimes absent or to 20 cm long, 4-5 mm diam., 0.2-0.4 x as long as petiole, dark purple, terete; spathe spreading-reflexed to twisted, coriaceous, dark purple tinged with preen (B & K red-purple 2/7.5), ovate-lanceolate, 6.5-15 cm long, 1.6-3.5 cm wide, broadest near base, inserted at 45° angle on peduncle, abruptly acuminate at apex (the acumen inrolled), rounded to subcordate at base, the margins meeting at 90-180° angle and stiffly rolled under; spadix deep red-violet to purple (B & K purple 2/7.5), cylindroid-tapered, 4-14 cm long, 7-9 mm diam. near base, 4-5 mm diam. near apex; flowers rhombic to square, 2.6-3 mm long, 1.5-3.5 mm wide, the sides ± straight; 4-6 flowers visible in principal spiral, 5-8 in alternate spiral; tepals matte, densely greenish punctate, minutely papillate; lateral tepals l .9 mm wide, the inner margins straight to convex; pistils not emergent, rectangular, minutely and barely exposed and somewhat glossy, violet-purple (also reported as white); stigma slitlike; stamens emerging slowly from the base, in a regular progression, weakly exserted then retracting, grouped in a tight cluster above pistil; filaments flattened, translucent, 0.3-0.5 mm long, 0.6-0.7 mm wide; anthers yellow, 0.5-0.6 mm long, 0.7-0.9 mm wide, inclined over pistil; thecae ellipsoid, scarcely divaricate; pollen yellow (B & K yellow 9/5), sweet-scented; INFRUCTESCENCE with spathe usually persisting; spadix to 35 cm long, 2.5 cm diam., bearing berries in the basal portion only; berries pinkish with metallic sheen, darker in the apical third, obovoid, acute to rounded at apex, 9-10 mm long; pericarp thin; seeds 2 per berry, light brown, flattened, 6 mm long, 5 mm diam., 2 mm thick.
    Habitat
    Premontane wet forest-basal belt transition.
