Mammillaria dioica is most widespread along the San Diego coast, but is also found in the Anza Borrego Desert area, as well as Baja California in Mexico. Spines are white except for the central fishhook spine, which is deep red, and longer than the others, though still generally shorter than some similar species. Stems are medium sized, up to 6 inches tall, and about 2 inches across, and may be solitary or part of clusters of up to 50 members. The flowers are the most distinctive feature of the plant owing to the deep red stripes through the middle of the undersides of the otherwise pale yellow petals.
