Cactus ID

[tripsis]

In my wanderings today I came across this:

Any idea what it could be? Considering the diameter of the stems, I figure it might make a decent, albeit nasty, grafting stock for seedlings.

Wow awesome find !!! not that i know what it is tho, an opunti-oid of some description? that's some nasty ass spin-age!!!

[tripsis]

I guess in retrospect, the spines are similar to some Tephrocactus species. An opuntiad is probably a pretty good guess. It has both glochids and large spines too.

Very interesting find, wish I could help with ID

It almost looks like a monster breed Pereskiopsis

[ferret]

something like a cylindropuntia leptocaulis or tetracanthus? i have a similar thing with barbed and sheathed spines, its a real asshole to bump into

[tripsis]

I think you got it ferret, it looks like Cylindropuntia leptocaulis from the pics I've looked at.

I wonder how it would do as a stock?

should be worth a shot, the piece that I planted definately seemed to grow faster than pereskiopsis. I'd probably try trimming/burning the spines if I was going to try and use it as stock after a pretty traumatic (/comical) experience! let us know how it goes, the plant in my garden definately needs a decent pruning soon..
