Mammillaria bombycina (silken pincushion cactus) is native to Jalisco and Aguascalientes states, in western central Mexico. Because of illegal collecting, the wild population is considered to have a vulnerable status.

It grows to 20 cm (8 in) tall and spreads indefinitely via offsets. The bulbous tubercles, surrounded by downy white hairs, have short white spines and much longer brown curved spines. Circular clusters of deep pink flowers are borne on the upper surface in spring and summer.
