Sulcorebutia breviflora (Cactus)

 It is an hemispherical cactus. In the past it was defined as a solitary cactus, however, nowadays it can also be found in the form of a central sphere surrounded by many smaller offsets, which makes it the characteristic of the species of this genus. It is very famous for its beautiful bright yellow flowers, which bloom abundantly in the period between spring and summer.
