Origin and Habitat: Echinocactus parryiSN|938]]SN|938]] is endemic of Chihuahua, Mexico (extent of occurrence of less than 20,000 km2)
Altitude: 1100 to 1300 metres above sea level.
Habitat: Grows on mountain foothills on rocky and gravely slopes in a very dry deserts environment mostly in xerophyllous scrub. Echinocactus parryiSN|938]]SN|938]] grows solitary or in spreading clumps and is locally abundant. Illegal collection, rock mining and extraction of construction materials affect some subpopulations.

Description: Globose depressed or shortly cylindrical, remarkably similar in morphology to E. polycephalus but distinct by the manner of growth and whiter spines. This Echinocactus is usually solitary but can branches spontaneously under normal conditions.
Stem: Glabrous, greyish-green, 20 to 30 cm high and 25 to 40 cm. in diameter (but typically under 35 cm in diameter)
Areoles: Roundish, with abundant greyish wool.
Ribs: Approx 13, acute. The juvenile Echinocactus looks quite different from the mature specimens. In fact, as with other Echinocactus and Ferocactus seedlings, the rib structure is not yet completely apparent, and they have pronounced tubercles making them look superficially like Mammillarias.
Spines: Dense, stout, angled, and ringed, chalky white to greyish-pink that turn a darker (redder) colouring when sprinkled with water. The spines almost obscure the plant bodies and restrict the small yellow flowers from opening fully.
Flowers: Yellow. They appear in summer.
Fruits: Woolly
