I want to also start a discussion on jointing and odd termination issues.
I'll start out with some extremes and deal with it more when I have time and a decent conection to upload a bunch more images
Cristation is the most extreme terminal weirdness I know of
The upper left is the pachanoi from Ecuador at the HBG
The right is a JuulXperuvianus from Sacred Succulents
The lower left is a photo by Evil Genius (who gave me permission to use this image) showing an unlabelled crest that MIGHT be a macrogonus crest. Note the occasional presence of tiny awlshaped solitary centrals and grey felting.
However this is pretty odd too.
This thing is a Harry Johnson collection he called aff. huanucoensis. That is about all that is known about it. I've not yet seen its flowers.
Normal tip is on the left but check out what is going on on the right. Pay particular attention to the constrictions, partial jointing, total jointing and odd scarring as well as that weird lack of effective areole separation that occurred at the apical meristem on the column on the left in the right hand image.
I will revisit this again with many more images taken of different plants. Some are posted here already.
Look also at the HBG macrogonus pictures I have posted under How to recognize a macrogonus for some more instances of jointing behavior and watch for constrictions, complete & partial jointing and that odd scarring.
Please add images of jointed cacti as this is going to get not just weird but interesting.
I have some ideas but far more questions than answers.
