Taxonomy
The first description as Echinocactus spiniflorus by Karl Moritz Schumann was published in 1903.[4] The specific epithet spiniflorus is derived from the Latin words spina for 'sting' or 'thorn' and florus for '-flowered' and refers to the scales on the flower tube of the species. Curt Backeberg placed the species in the genus Acanthocalycium in 1936.[5] Further nomenclature synonyms are Echinopsis spiniflora (K. Schum.) A. Berger (1929), Spinicalycium spiniflorum (K. Schum.) Frič (1935, nom. inval. ICBN article 43.1) and Lobivia spiniflora (K.Schum.) Rausch (1987).
