Cactus ID please

[eco]

Please take the time to look at 4 pics of mine. Cacti aren't my strong point at all but after a recent visit to Bolivia I'm hooked.

Two of the pics (shorter spined cacti) I'm almost sure are San Pedro. Just check me on that. Also, what species is the longer spined cacti?

Wow!

Where is the location these are growing in and do you know if they are natural to that area or if they are introduced?  Did you take these on a trip?  Or are these is the States (Michael prays deeply)?

If they are photos from South America I'll suspect introduced, but the location might be helpful.  

The first two photos (the shorter spined one and the small branch) appear to be like IcarosDNA's T. peruvianus.  No T. pachanoi there.

The ones with the thick spination look like the standard T. peruvianus.

I like the one without the thick spines.  I wish I could get a clipping or two of those for sure...but I doubt it...since I am broke as I can possibly get.

Michael, the short spined one looks a lot like the WOH peruvianus that I have. PM me and maybe we can trade.

Nice photos! It interests me to see cacti growing in a natural state,i infer from what you said that these pics were taken in Bolivia.

      I wonder what natural pests they have there,they do not look ravaged in any great way. That bundle of columns has been there perhaps for a while,it has pups it seems,growing out of them. Also spotted another coloumnar cacti in the back of one of the stands,looked many ribbed.

      Can you describe where in Bolivia these photos were taken,elevation,that sort of thing? The setting,jus for guessing,looks 'temporate' to semi-arid,noticed the tree in the background,and grass(?) all around.

     One of these days I will do some general reading,and determine the ranges of these cacti, my own best approach. I sure get tired of seeing cacti in pots,I may experiment and place some in the ground. Or do as Eu..... suggested in another post, pots in the ground.

Ok, I should have given more info and I wont even be able to give it all now... maybe later tonight. It's not from the States or from Bolivia. The pics were actually taken in southern South Africa which is where I'm from. I'll post more info on the actual weather conditions of the place when I can. But for the time being.. it's very hot there, with very little humidity and it's a serious wine producing region that sources water from a relatively nearby and large river. It's in the region where most succulents are found.

Thanks for all the replies. Appreciate it.

Edit: and I think that means they're introduced... we don't get cacti here only other succulents.

As I understand it,cacti are not native. thats why some go-arounds w/Hoodia. That makes even more interesting.

A little more info on the weather in that part of south africa...
Temperatures: cool wet winters (2 - 25 °C) and hot dry summers (10 - 38° C).

And for interest sake here are two pics of what the locals in Bolivia termed San Pedro. I unfortunately never came across wild Trichs in bolivia even though I was pretty much on the look out for it. But I did come across tons and tons of cuttings (like in the pics) and quite a lot of dried pieces in street stalls and markets.
