Astrophytum Myriostigma var. Nudum cv. Kikko Rampo
Astrophytum myriostigma is a quite variable species and several breeds do exist. This rare Japaese cultivar is unmistakable for its pointed tubercles along the ribs edges, in fact its areoles stick out with large notches between them, giving them a saw tooth look. Usually the young seedlings appears nothing special and looks like normal myriostigma, and barely shows any trace of saw teeth, but they start to produce the distinguishing indentation and turn into an amazing adult as they get 3 to 7 years old.
