Notes
Turbincarpus schwarzii is here recognized at species rank based on its phylogenetic position with respect to the other Turbinicarpus species (Vázquez-Sánchez et al. 2019). Morphological differences can be found in the flowers: they are about 3.5 cm wide and with white perianth segments in T. schwarzii, and c. 2.5 cm wide and with perianth segments hat are magenta in color with white tones at the edge of the tepals in T. schmiedickeanus (Donati & Zanovello 2004).
The recognition of Turbinicarpus polaskii has been the subject of discussion. Taxonomic treatments such as Anderson (2006) and Hunt (2006) treat it as synonym of T. schmiedickeanus subsp. schwarzii. Donati & Zanovello (2004) propose the recognition of this taxon at the subspecific level. Based on the comparison of seedling development and seed characters, they conclude that there are greater morphological similarities with T. schmiedickeanus subsp. macrochele. A molecular analysis is still required in order to assess the recognition of this taxon, as it has not been sampled by Vázquez-Sánchez et al. (2019).A
