Ariocarpus retusus

Ariocarpus is a unique genus in the Cactus Family native to northeastern Mexico and across the border into Texas. The hard tubercles making up the stem look almost leaf-like, and because of this people often do not realize it is a cactus. The flower color in Ariocarpus retusus ranges from white to faintly blushed with pink to deeper pink.
