Re: Puzzle Cactus
Grafted. Looks like the stock has branched and is starving it. I'm going to go with Stenocactus.

Re: Puzzle Cactus
It's grafted on Harrisia jusbertii which is a pretty good stock, but it may be a graft that is failing with poor adhesion. Probably best to take it off and root it down.

Re: Puzzle Cactus
Yes, the stock is Harrisia, and the offsets could have done with coming off, which they would have if the plant was mine ! the scion however is not Stenocactus (are they not Echinofossulocatus any more?)

Re: Puzzle Cactus
Could the scion be Matucana madisoniorum? That was my initial gut reaction to finding out it wasn't Stenocactus.
EDIT:
Then again if the plant has somewhat distorted ribs that could explain the random arrangement of spines rather than the Matucana guess.

Re: Puzzle Cactus
The scion is a genus that only occurs in Mexico, where this picture was taken.
