description

Mammillaria setispina has a gray-green plant body that sprouts from the base, creating larger groups. The individual shoots are up to 30 centimeters long and 3 to 6 centimeters in diameter. The individual warts are conical in shape. The axillae are woolly. About 1 to 4  central spines are 2 to 5 inches long. In contrast, the 10 to 12 radial spines are unevenly flexible and whitish in color with dark tips. The 5 to 6 centimeters large zygomorphic flowers are scarlet red. The stamens stick out strongly. The fruits are dark red and 2 inches long. The seeds are black.
