Flowers of Mammillaria pondii subsp. maritima

Mammillaria pondii initially grows individually and later forms small groups. The individual shoots are cylindrical and up to 30 centimeters long and 3 to 7 centimeters in diameter. The smooth warts are conically arranged. The axillae have bristles. One of the 4 to 5  central spines is always stiff and strongly hooked, whitish with a dark brown tip and about 2.5 centimeters long. The 20 to 30 slender radial spines are white, sometimes brown in color. The flowers are up to 5 inches long, red and crooked. Sometimes the stamens protrude. The fruits are red.

Mammillaria pondii is still treated as Cochemiea in the English original . Lüthy (1995) lists the species Mammillaria maritima and Mammillaria setispina as subspecies of Mammillaria pondii , which are not very different .
