Taxonomic note. The taxonomic boundaries of this species are still object of debate, some authors think that Echinopsis calorubraSN|21048]]SN|21048]] should be placed under the name Echinopsis rauschiiSN|21037]]SN|21064]] H.Friedrich, and should include Echinopsis rojasiiSN|21048]]SN|21042]] Cárdenas. According to Hunt et al. (2006) the concept of E. calorubra also includes Echinopsis cardenasianaSN|21037]]SN|21206]] (Rausch) H.Friedrich.
