    Distribution

    Anthurium macphersonii is endemic to Premontane rain forest (bp-P) of the Western Cordillera of north western Colombia. Within the department of Antioquia, all collections occurred in the adjacent municipios of Frontino and Urrao. This species might range further to the south into the Municipio Salgar and beyond, but collections from that area begin to diverge in a variety of features and might represent other species or hybrids.
