Notes

Butterworth & al. (2002) found L. williamsii as sister to Obregonia and L. diffusa (Croizat) Bravo as sister to Acharagma, yet both with only moderate support. In contrast, Lophophora williamsii and L. diffusa were resolved as sisters with moderate support in the study of Vázquez-Sánchez & al. (2013), who also found high support for the sister relationship of Lophophora and Obregonia, justifying generic rank for both.A At present, about four species are known by combination of some characters such as papillae on the epidermis of the stem, the micromorphology of the seed, as well as the concentration of some alkaloids. A detailed population study (morphological, genomic) is required to circumscribe the species and their relationships. B
