Terrestrial or epiphytic; internodes 1-1.5 cm long; 1.3-2.0 cm diam.; cataphylls 5--6 cm long, drying reddish brown, persisting intact at uppermost nodes, as a loose reticulum of tan or red fibers lower; petioles terete, (22-) 31-56 (-80) cm long (averaging 40.1 cm), 2-5 mm diam. at middle; blades ovate-elliptic, weakly cordate, caudate-acuminate at apex, weakly cordate at base, 19.5-37 cm long, 10-24 cm wide (averaging 28.7 x 18.5 cm), 1.5-2 times longer than broad, from half as long as to 1.1 times longer than the petioles, broadest between point of petiole attachment and middle, convex at margins, moderately thin; both surfaces glossy, drying olive; anterior lobe 19-38 cm long; posterior lobes 2-6 cm long, 2-6.5 cm wide; sinus arcuate to triangular, .5-5 cm deep, 3-5 cm wide; midrib convex, narrow, and scarcely paler above, round-raised, moderately paler and weakly ribbed below; basal veins 4--6 pairs, free to base; primary lateral veins over 20 per side, departing midrib at 45°--60° angles, ascending to collective vein, quilted-sunken above, narrow and pleated-raised below; tertiary veins in part sunken above, raised below; collective vein arising from base, 2-4 mm from margin. INFLORESCENCES erect, shorter than leaves; peduncle 22-55 cm long, 2-4 mm diam. at middle; spathe reflexed-spreading, chartaceous, green to violet-purple, lanceolate, 4-9 cm long, 1.0-1.5 cm wide; spadix reddish violet to maroon, moderately glossy, sessile, oblong, 8-21 cm long, 4-5 mm diam.

Anthurium longicaudatum ranges from Colombia (Narino) to Ecuador (Carchi, Cotopaxi, Esmeraldas, Imbabura, Pichincha) at elevations of 900-2,450 m in Premontane wet forest, Premontane rain forest, and Tropical moist forest life zones. It is moderately common in the regrowth forest at La Planada.
