The first description as Cereus versicolor was made in 1931 by Erich Werdermann and Curt Backeberg. The specific epithet is derived from the Latin word versicolor for 'colorful' and refers to the differently colored thorns. Curt Backeberg placed the species in the genus Haageocereus in 1936.[2] A nomenclature synonym is Binghamia versicolor (Werderm. & Backeb.) J.West (1932, incorrect name, ICBN article 11.4).
