Epiphyte; stems 20 cm or more long, 1.5-3 cm diam.; internodes 1-2 cm long; leaf scars 1-1.5 cm wide; roots green to brownish, ca. 5 mm diam., smooth, descending; cataphylls subcoriaceous, brittle, 13-18.5 cm long, tinged violet, the epidermis cracking, acuminate at apex, held around petiole, drying tan, persisting more or less intact, ultimately deciduous. LEAVES spreading to pendent; petioles 10-44 cm long, 7-9 mm diam., weakly flattened to shallowly and sharply sulcate adaxially, sometimes faintly 1-2-ribbed abaxially, the epidermis turning gray to tan and cracking; geniculum 2-4 cm long; blades coriaceous, oblong to oblong-elliptic or oblong-ovate, acuminate at apex, rounded to shallowly lobed at base, (25-)39-85 cm long, (6-)9-18.5 cm wide, broadest near middle or just below; anterior lobe 38-81 cm long, the margins straight to weakly convex; posterior lobes 1-5.5 cm long (from apex of sinus to outermost point); sinus parabolic to hippocrepiform or sometimes spathulate; the surface matte, midrib acutely raised above, diminishing toward apex, convexly raised below; basal veins 3-5 pairs, usually free to the base, flat to prominulous above and below; primary lateral veins 12-20 or more per side, departing midrib at 30-35° angle, weakly sunken above, flat to prominulous below, interprimary veins flat above and below, lesser veins obscure; collective vein arising from the first basal vein, sunken above, prominulous below, 3-5 mm from margin. INFLORESCENCE spreading, shorter than leaves; peduncle 11-32 cm long, 5-9 mm diam., terete, one-third to one-half longer than petioles; spathe subcoriaceous, pale green, tinged red-violet at edges, lanceolate, usually brittle, 5-12.5 cm long, 1.5-2.2 cm wide, broadest at middle or below, acuminate at apex, rounded to acute at base, the margins weakly turned up, thin and cracking; spadix medium green (B & K Yellow-green 6/7.5), slightly tapered toward apex, 6-21.5 cm long, 5-11 mm diam. near base, 4-7 mm diam. near apex; flowers square to 4-lobed, 2.2-3.2 mm long, 2-2.7 mm wide, the sides sigmoid, 7-9 flowers visible in the principal spiral, 5-7 flowers visible in the alternate spiral; tepals semiglossy, minutely papillate, lateral tepals 0.7-1.9 mm wide, the inner margins straight and flat; pistils scarcely emergent, pale greenish white; stigma ca. 0.4 mm long; lateral stamens emerging nearly to apex of spadix before third and fourth stamens emerge; anthers white, 0.4-0.6 mm long, 0.3-0.7 mm wide, held over and covering pistil; thecae ellipsoid, not divaricate, pollen white. INFRUCTESCENCE with obovoid-ellipsoid, purple berries, ca. 6 mm long, 3-3.5 mm wide; mesocarp gelatinous with linear raphide cells; seeds 2, 2.8-3 mm long, ca. 2 mm wide, with minute appendage at apex, longer appendage at base.
Found in the Puntarenas Province of Costa Rica, Panama and Colombia (Chocó). In Panama it has been collected principally in Coclé Province in the vicinity of El Valle and north of El Copé. One sterile collection from Veraguas (Croat 27782) may also be this species.
