Ariocarpus (Roseocactus) fissuratus 'lloydii', отдавна съществува в природата. Вероятно става дума за някаква японска "пъстра" безхлорофилна форма.

From the western side of the Big Bend Region, and eastwards along the Rio Grande to the confluence with the Pecos (type locality) and beyond almost to the Atlantic coast, also in parts of central northern Coahuila. A much larger growing, more hemispherical plant is found in southern Coahuila near Parras, westwards as far as Nazas in Durango and southwards into northern Zacatecas, this was described as A. lloydii. (Rose 1911) and later as A. fissuratus var. lloydii.. A form intermediate between the two, is found between Cuatrocienegas and Estacion Marte in central Coahuila and has been named A. intermedius.. A. loydii and A. intermedius are now reduced to synonymy under A. fissuratus as part of a North - South cline. A. fissuratus is found on fragmented limestone hillsides and flats in compacted sandyclay soils at altitudes of up to 1200m. A fourth variety, A. f. var. hintonii, which grows much further south in northern San Luis Potosi, is now considered to be a sub-species of A. bravoanus
