Turbinicarpus saueri comprises eight subspecies included in this taxonomic treatment. According to Lüthy & Moser (2002), these subspecies differ mainly by floral and stem morphology: large stems and flowers with white perianth (T. saueri subsp. ysabelae); small stems and flowers with pale pink perianth (T. saueri subsp. nelissae), stems with numerous spines (T. saueri subsp. knuthianus), and stems with few spines (T. saueri subsp. nieblae). Four of the eight subspecies were included in the phylogenetic analysis of Turbinicarpus, but no close relationship was shown between the subspecies (Vázquez-Sánchez & al. 2019), they were intermixed with other Turbinicarpus species, suggesting they might actually merit species rank. Still, the relevant nodes were unsupported or weakly supported. Therefore, a more comprehensive study phylogenetic / taxonomic study of all eight subspecies would be required to arrive at a better understanding of species-limits in this group. The four subspecies sampled by Vázquez-Sánchez & al. (2019) are here provisionally accepted at species rank.A
