General Description

Appressed hemiepiphyte, climbing to 5 m high; stems usually 1.5-3 m long; roots elongated, to 5 mm diam., epidermis drying dark brown, smooth, semi-glossy, weakly folded, sometimes flaking; internodes 2-6 cm long, 2-6 cm diam.; epidermis drying smooth but folded and wrinkled, light brown to yellow-brown and closely longitudinally wrinkled; cataphylls unribbed, 25-28 cm long. LEAVES with petioles subterete, obtusely and weakly flattened adaxially (30)46-102 cm long, drying dark brown, to ca. 1 cm diam. midway, sheathed (8)14-23 cm when subtending an inflorescence; blades narrowly ovate-cordate to ovate-triangular, 40-67 cm long, 25-57 cm wide, subcoriaceous, weakly bicolorous, dark green and semi-glossy above, slightly paler and weakly purple-tinged below, drying light grayish green to grey or dark yellow-brown above, light yellowish green to yellow-brown below, abruptly acuminate at apex, prominently lobed at base, the lobes mostly broadly rounded, incurved toward sinus; sinus hippocrepifonn to arcuate or closed; midrib ± flat above, drying weakly raised, medially sunken toward apex, convex and paler below, drying convex and paler; primary lateral veins 4-8 per side, usually alternating with interprimary veins (these only slightly less prominent than primary lateral veins), arising at a steep angle then spreading at 55-75°, weakly sunken above, drying weakly raised and slightly paler above, convex and paler below, drying convex, much paler and yellowish-brown; basal veins 6-10 per side, 1-2 free to the base, the 3rd pair coalesced with higher order veins 3.5-11 cm; posterior rib nearly straight, 11-17.5 cm long, naked 2.5-4 cm along the sinus; minor veins moderately visible; secretory ducts visible, intermittent; lower surface weakly granular at 30 X magnification. INFLORESCENCES 2-7(12) per axil, producing a strong sweet scent of citrus; prophylls pink, 2-ribbed, one rib blunt, the other acute; peduncles pale green to pink, 8-21(25) cm long, drying 3-7 mm diam., gray-brown; peduncle & spathe flattened dorsiventrally; spathe 7.5-10 cm long, scarcely differentiated into tube and blade; outer surface at first pale green to yellowish, with salmon-colored flush, becoming deep salmon to red-orange, sometime greenish to yellow-green on tube and peach-colored to orange on blade, sometimes reported as yellow, orange or red throughout, drying reddish brown; inner surface whitish or cream, suffused with peach or cream-pink above middle; spadix ± cream-colored, 6-9.5 cm long; pistillate portion pale green, 2.5-3 cm long in front, 9-10.5 mm diam. midway, about as wide as the sterile male flowers; pistils pale green, with elongate protruding style 6-8 mm long, 0.4 mm diam., directed toward the apex, articulated and falling off just above the ovary with age; stigmas globular, ca. 1 mm long, 1.3-1.4 mm diam. at apex, slightly narrower on ovary, the apex almost circular to irregularly angular, often 5-sided, the margin thick and raised; locules 8-9; ovules 1 per locule, borne in a gelatinous envelope 0.7-0.8 mm long; ovules 0.35 mm long, funicle much shorter than ovule; staminate portion 4.2-6 cm long, barely or not at all constricted, with the sterile portion obscure, 6-9 mm diam., broadest in lower 1/3; sterile staminate portion short, inconspicuous, slightly narrower than fertile portions; staminate flowers 1.4-1.7 mm diam., 4-5-androus. Berries pale green to orange; seeds oblong-elliptic, brown on drying, 1.5-1.6 mm long, 0.6-0.7 mm diam.

Diagnostic Description

The species is recognized by its thick internodes, often longer than broad and drying with a smooth, light brown epidermis, as well as by its narrowly ovate-cordate blades with pale-drying major veins. More critical for recognition are the clusters of numerous, small, more or less pale orange inflorescences in one or more leaf axils, and especially the unusual pistils that have long, protruding, tapering styles.


The species occurs in Tropical wet forest (bmh-T), Premontane wet forest (bmh-P) and Premontane pluvial forest (bp-P).


It ranges from Colombia to Ecuador, along the Pacific slopes in Colombia (Cauca, Chocó and Nariño Departments) and along the lower Pacific slopes of the Andes, at 30-1,100 m elevation, in Ecuador (Cotopaxi, El Oro, Esmeraldas, Guayas, Los Ríos and Pichincha Provinces).
