forma mostruosa (Monstous form): This plant is a rare oddity with areoles merging to form concentric lines. The epidermis is harder than in the normal Notocactus and cracks easily but this is not a defect and the plant will not suffer for this, and also the fact that the body splits open permits to the plant to develop original and strange shapes.
 

 


 
The fact that the plant's body splits open is not a defect but the peculiar characteristic of this odd plant. All the stems will soon crack permitting the plant to develop original and strange shapes.
