Ariocarpus kotschoubeyanus LRM280

This is kotschoubeyanus very close to Ted Anderson’s type locality east of Entronique Huizache, SLP.  It grows in a typical ‘kot’ gypsum mud silt plain with open, low vegetation.  It is the ‘standard kot’ without varietal name, but in practice it is little different except, perhaps, for the darker flower than vars. macdowellii or albiflora.
