Taxonomy
The first description as Echinocactus spiniflorus by Karl Moritz Schumann was published in 1903. 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. 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).
