Typifications of some species names in Anthurium section Pachyneurium (Araceae).

During a taxonomic study of Anthurium sect. Pachyneurium, it was found that the names of four species required typification. Verification of the protologues and cited collections is discussed and typifications are proposed as follows: the illustration is designated as the neotype of Schott. A lectotype is designated for G.S.Bunting since the holotype, cited in the protologue at MY, was not found there. An epitype is selected for Schott because the lectotype illustration of J.M.C. Vellozo () lacks sufficient detail to determine it unambiguously to species in A. sect. Pachyneurium. A lectotype is selected for Hook.f., a synonym of .
