Small, low Mammillaria from southern Mexico with purplish pink flowers. Stems are generally solitary and green, with 0-6 central spines and 20-36 fine radial spines. Axils may have some or no wool. Flowers are bright pinkish purple. Fruit is cryptocarpic. From Oaxaca.

The two subspecies are Mammillaria (Mammillaria deherdtiana subsp. deherdtiana) (8 or more spirals of tubercles, no central spines, 33-36 short radial spines) and Mammillaria (Mammillaria deherdtiana subsp. dodsonii) (8 or fewer spirals, 1-6 dark central spines, 20-21 long radial spines).
