The genus
Rhodocactus (A.Berger) F.M.Knuth has been brought into synonymy with this genus, as well as different orthographic variants: Peirescia Zucc. (orth. var.), Peireskia Steud. (orth. var.) and Perescia Lem. (orth. var.).

Uses


The genus is not of great economic importance, the most common usage being as hedges;
they are easily transplanted and quickly grow into an impenetrable thicket, as well as flowering prolifically. Being more tolerant of moisture than more succulent cacti, they can be used as rootstock for grafting of
Zygocactus to create miniature trees.
