    Distribution

    Anthurium boosianum is at present known only from the western slopes of the Andes in Ecuador with collections from western Ecuador in Carchi Province and in Pichincha Province on the slopes of Volcan Pichincha in Lower montane wet forest and Premontane wet forest life zones. It is certainly to be expected in the intervening area between Esmeraldas and Pichincha on the western slopes of the Andes as well as in adjacent Colombia in Narino Department at 1,000 m in a Premontane rainforest life zone.
