This evergreen, perennial cacti is spherical to shortly columnar in shape and does not possess spines. Usually growing to around 20cm in height, this species is grey-green in colour, possibly developing a red-purple tinge with good, strong sunlight. It has between 3-7 distinct, raised ribs (on average 5) running vertically around the plant surface and produces yellow, daisy-like flowers. These measure approximately 5cm in diameter and may take a red colouration in the centre. Originating from northeastern Mexico, this species requires high levels of sunlight and dry conditions to thrive.
