Mammillaria tetrancistra is characterised by its many (20 to 60) small, white to brown radial spines, which completely cover the green stem, while the 1 to 3 or 4 central spines are red, hooked, angled outwards and much longer. The plant forms small clusters, usually with fewer than ten stems but sometimes as many as 30. The maximum length of each stem is 6 inches. Pink flowers appear in spring or summer, followed by bright red fruits, 1 inch long, with a pit at the upper end, left by the residual petals.
