Schumann describes 3 varieties, all apparently from Mendoza, which we have merged 

 into the species. Plants as seen in the field show even greater variation than is called for 

 in Schumann's descriptions, but they all evidently grade into one another.

 former was described as depressed, 12 to 15 inches in diameter, only 4 to 5 inches high, and 

 with 28 ribs. The type locality was Bellavista, Chile. It should be compared with 

 Eriosyce sandillon and its relatives.* Echinopsis dumeliana Cels (Salm-Dyclc,^Cact. Hort.
