Simple or cespitose, globular or somewhat depressed or sometimes short-columnar, 9 cm. high or 
more, sometimes 12 cm. in diameter; ribs 10 to 15, broad at base, somewhat tubercled, especially 
above, acutish; areoles elliptic, 10 mm. long; spines 7 to 10, all radial, spreading, somewhat flattened,

3.5 to 4 cm. long, pinkish to nearly white, short-campanulate; inner perianth-segments oblong, 
3 cm. long, obtuse or acute; scales on the ovary broad and rounded, their margins scarious. 
Type locality: Not cited. 
Distribution: Reported from Brazil, Uruguay, Paraguay, and Argentina. We know 
it definitely from Argentina, where it was collected by Dr. Rose in 1915, in Cérdoba. — 
Schumann (Gesamtb. Kakteen 405. 1898) describes briefly the three following varie- 
ties: albispinus, parisiensis, and hybopleurus. 
Echinocactus ourselianus Monville (Salm-Dyck, 
Cact. Hort. Dyck. 1849. 34. 1850) is cited by 
Schumann as a synonym of this species, but it was 
never published; the name was attributed to Cels 
by Salm-Dyck. Its variety albispinus (Monats- 
schr. Kakteenk. 5: 111. 1895) is sometimes met 
with.
