Notes

Turbinicarpus has been found to be polyphyletic in the molecular studies of Bárcenas & al. (2011) and Hernández-Hernández & al. (2011). The most comprehensively sampled dataset of Vázquez-Sánchez & al. (2013) showed Turbinicarpus to fall into three separate clades. Turbinicarpus was re-circumscribed restricted to 11 species, while species with a tuberous root connected to the body with a long, thin neck are now segregated as Rapicactus based on these results. Two further species (T. horripilus (Lem.) V. John & Říha and T. pseudomacrochele (Backeb.) Buxb. & Backeb.) are outside the main Turbinicarpus clade (incl. Gymnocactus) and a new generic name would be needed for them. Recent treatments by Lüthy (2002) and Lüthy & Moser (2002).
