Note

Parodia gibbulosaSN|5819]]SN|5810]] was a provisional name used by Ritter in 1958, but even if the plants was widespread in cultivation it remained undescribed. Meanwhile Brandt validly published "P. gibbulosoides" in 1971. At last nine years later Ritter published the description of its “P. gibbulosa”, but it was already too late and this name is universally recognized as a synonym.
