"Hexaedrophorus" comes from the Greek "hexa" = six and "hedra" =plane, seat
and "phoros" = carrying, for the six angled tubercles.
A solitary and quite variable cactus with flattened stems from San Luis Potosi, Tamaulipas, Nuevo Leon and Zacatecas areas of Mexico. Many local forms are known, often formally described, that differ in stem, spine or flower morphology. Because of the large variability of the species in the whole distribution area, none of these are recognized today. Depressed or globose, bluish , olive-green, or greyish-green eventually tinged in pink or purple, 2-5" tall , 8" in diameter (eventually grows a little taller in cultivation). Spines are usually strong and variable in length depending on the plant often difficult to distinguish as centrals and radials. Flowers are silvery-white or rarely pinkish with more or less magenta midribs, up to 10 in diameter. Easy to cultivate but very slow growing. The plant in the collection is planted in a 4" pot.
