Description
Mammillaria heyderi var. macdougalii is a broad, flattened cactus that grows on hillsides in the desert grassland above 4000 ft elevation. The large yellow flowers usually open in a wide ring. In good habitat, an old plant may reach a diameter of 10 inches yet be less than 2 inches high. The large, silvery fruit are enjoyed by birds and rodents during the arid fore summer before the Monsoon. Compare with Mammillaria grahamii.
