Taxonomy
The first description as Cereus pomanensis was made in 1897 by Frédéric Albert Constantin Weber in Karl Moritz Schumann's complete description of cacti.[6] The specific epithet pomanensis refers to the occurrence of the species near Pomán in the Argentine province of Catamarca. Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Harrisia in 1920.[7] Further nomenclature synonyms are Eriocereus pomanensis (F.A.C.Weber) A.Berger (1929) and Echinopsis pomanensis (F.A.C.Weber) Anceschi & Magli (2013).
