Taxonomy

The first description as Echinocactus haynii was made in 1850 by Christoph Friedrich Otto in Joseph zu Salm-Reifferscheidt-Dyck's Cacteae in horto Dyckensi cultae anno 1849.[4] Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Matucana in 1922.[5] Other nomenclature synonyms are Mammillaria haynei (Otto in Salm-Dyck) Ehrenb. (1844), Cereus haynei (Otto in Salm-Dyck) Croucher (1878), Borzicactus haynei (Otto in Salm-Dyck) Kimnach (1960), Arequipa haynei (Otto in Salm-Dyck) Krainz (1963) and Echinopsis haynei (Otto in Salm-Dyck) Molinari (2015)
