  ## Description
  
  Mammillaria painteri is characterized by small, spherical mounds that sprout conical or cylindrical tubercles. The globose mounds, or stems, are dark green and can range from one to eight centimeters in height and diameter. In its monstrous form, Mammillaria painteri forma mostruosa, it can grow to be larger than that. The mounds may be clustered together or singular. It typically has white or pale light yellow flowers. Rarely, it will sometimes produce light pink or magenta flowers as well. The flowers are shallow and funnel-shaped.
  
  This species is known to withstand temperatures down to at least -2 or -5 degrees Celsius if kept completely dry. It is not known to do well in direct, intense sunlight, mainly in summer months. It is also sensitive to red spider mite.
