Monstrose?
What was the name of this cactus?
Was this crested or montrose? What was the name?
Thanks!

And there are more lovely photos from Cactus Jungle by Paula on flickr.
Paula,
It is a Crested form of Myrtillocactus geometrizans
the true form looks sort of like spiny blue cucumbers.
Take care,
Hap
