This is a small ploschadochka, from which grow spines, hairs, or bristles. Euphorbia, which are often confused with cacti, have no areola, they have the spines grow directly from the plant body.
A round cactus, the areola of which are not located on edges, and protruding dermal papilla, and gives abundant root growth is likely to be mamillaria or Rebutia. They can be distinguished until flowering. Have mammilyary flowers appear around the top, Rebuzzi – near the base of the body of the cactus.
