Copiapoa hypogea along with C. humilis are the most commonly seen Copiapoas in collections. They flower easily, with characteristic for the genus yellow flowers.
It would be difficult to make an impression of the whole plant from my picture, but that was not the intention either ))

Ariocarpus fissuratus

Summer is almost over and Ariocarpus flowering season has started. A. fissurratus stem is grey and textured like rock, blending to the environment. The fleshy root is much larger then the stem above the ground, and the plant grows almost flat to it's surface.
