Mammillaria duwei is a species of flowering plant in the cactus family. It is endemic to Mexico, where it occurs only in the state of Guanajuato. It is known from only one location. [1] It is known commonly as the biznaguita. [1]
This is a critically endangered species due to its limited distribution and illegal collecting for trade. There are perhaps 500 mature individuals left in the wild. [1]
