General Description

Epiphyte or occasionally terrestrial; stems usually less than 30 cm long, occasionally to 1 m long; roots numerous, scattered along stem; cataphylls moderately thin, 15-25 cm long, narrowly acuminate at apex, drying tan (B & K Yellow-red 9/10) usually deciduous, with a few thin fibers sometimes persisting. LEAVES moderately thin; petioles 25-73 cm long, 3-7 mm diam., terete, sometimes weakly sulcate; geniculum 1.5-2 cm long; blades hastate-trilobate, erect or spreading from the erect petioles, 20-65 cm long, 10-43 cm wide, gradually to abruptly acuminate at apex, prominently lobed at base; anterior lobe 21-55 cm long, constricted near base; posterior lobes nearly orbicular (or rarely oblong), some times directed conspicuously upward from point of petiole attachment; sinus usually spathulate or hippocrepiform sometimes parabolic, usually rounded at apex; both surfaces semiglossy to glossy; midrib obtusely raised above, sunken toward apex, prominently raised below; primary lateral veins 15-30 per side, departing midrib at 45°-50° angle, sunken above, raised below; lesser veins less conspicuous; basal veins 5-9 pairs, 3-4 coalesced 1-4.5 cm; posterior rib naked, weakly turned up along outer margin; collective vein arising from one of the lowermost basal veins and extending to apex, 3-7 mm from the margin. INFLORESCENCE erect, shorter than leaves; peduncle (5)11-20(32) cm long, 4-6 mm diam., terete; spathe moderately thin, pale green, some-limes tinged reddish, oblong-lanceolate, 6.3-19 cm long, 2.7-3.5 cm wide, abruptly acuminate at apex, rounded at base, inserted al 60° angle on peduncle; spadix golden yellow (B & K Yellow-red 8/10), 7-18 cm long, 7-9 mm diam. midway, tapered to 4-6 mm at apex; the flowers sub-4-lobed, 2.5-3 mm long, 2.9-3.3 mm wide, the sides ± straight to jaggedly sigmoid; 6-9 flowers visible in the principal spiral, 6-10 flowers visible in the alternate spiral; tepals yellow, glossy, lateral tepals 1-1.5 mm wide, the inner margin convex; pistils weakly emergent, pale green, translucent; stigma linear, ca. 0.3 mm long, brushlike and glistening as anthers emerge; stamens emerging in scattered manner slowly from base to apex, exserted to ca. 1.3 mm on white or translucent, flat filaments, the exserted portion of the filaments ca. 0.3 mm long, ca. 0.5 mm wide; anthers yellow, 0.5-0.6 mm long, 0.7-0.9 mm wide; thecae divaricate; pollen golden yellow. INFRUCTESCENCE arching-pendent: the spadix to 23 cm long; berries pale green, ovoid, 5-7 mm long; seeds 2, greenish-white, 2.6-3 mm long, 2.3-2.5 mm wide, 0.8-1 mm thick.

Habitat

Tropical wet, premontane rain, and lower montane rain forest.

Distribution

Known from Costa Rica to Colombia and Ecuador. In Costa Rica, the species ranges from Bijagua in the north to Tapanti in the south on the Atlantic slope. In Panama the species occurs on both slopes.
