    Distribution

    Anthurium pulverulentum ranges from Colombia (Cauca, Choco, Narino, Valle del Cauca), Ecuador (Cafiar, Carchi, Cotopaxi, El Oro, Esmeraldas, Guayas, Imbabura, Los Rios, Manabi, Napo, Pichincha), at elevations of 350-2,300 m (primarily from elevations above 1,400 m, but a few collections, especially those from Esmeraldas, are from elevations lower than 800 m), in Premontane moist forest, Premontane wet forest and Premontane rain forest life zones. It is apparently common at La Planada, with specimens collected in both primary and secondary regrowth forests, as well as along the margins of an old pasture along Sendero La Vieja. This species is a member of sect. Polyneurium, and it is recognized by its internodes longer than broad and weakly and finely transverse-ridged, its large, moderately thin, velvety leaf blades with many, closely spaced, deeply sunken primary lateral veins as well as by the inflorescence with a long, slender green spathe and its narrowly long-tapered bluish green spadix. Anthurium pulverulentum can be confused with A. subcoerulescens, which differs primarily in having basal lobes directed prominently outward, and in having a narrower anterior lobe. The latter does not occur at La Planada.
