Notes
The proposal by Lüthy & Moser (2002) to recognize this taxon as an independent species of Turbinicarpus schmiedickeanus (Boed.) Buxb. & Backeb. is followed. The trees of Vázques-Sánchez & al. (2019) show that T. jauernigii is not related to T. schmiedickeanus, in which it used to be included as a subspecies. The anatomy of the spines of T. jauernigii Gerhart Frank indicates that the spines have compact sclerenchyma, thick-walled fibers which make up spines that are hard, rigid to sub-rigid, mostly pungent (Mosco 2009). This character is shared with other species such as T. gielsdorfianus (Werderm.) John & Říha or T. lophophoroides (Werderm.) Buxb. & Backeb., but not with T. schmiedickeanus, which has non-pungent, papyraceous spines. A
