Yet another cacti identification request (updated)
    #4150492 - 05/08/05 04:17 PM (11 years, 6 months ago)

Hopefully the resident gurus are still up to our favorite game - Identify the Cactus. Bonus points for blindfolded guessing.

I took a stroll through my neighbourhood, and found quite a few columnar cacti. I eliminated all those that had hypertrophized trunk from which branches grew, and also those that seemed to have very small ribs. I do not know how to further identify a species (or at least eliminate the possibility of its being a trichocereus pachanoi/peruvianus/bridgesii), so here are the pictures:

Plant A:



Plant B:









Plant C:





Plant D:





And just to flaunt what I believe is an unusually large cactus (the distance is probably too great to enable identification), Plant E:

Bonus round - what is this? A nymphaea worth salvaging from this remarkably malodorous pond?

Thanks to all participants!

Looks like your hosting website does not allow image linking, why don't you upload those pics to the shroomery?

I would say plant B is a Trichocereus (something). But I'm no expert.

B would be safe to say.

And in the bottom left hand corner of the pic of the vary large cacti i think might be one also.

D could be Myrtillocactus geometrizans. It would be easier to ID the plant in flower.

Thanks to all who replied.
I've added a few more views of Plant B, which seems the most promising. One of the pictures is of the trunk - I'm somewhat concerned that one can discern what appears to be a half-buried wooden trunk, which to the best of my current understanding, would disqualify it from being a trichocereus.

As for the fine specimens A and C: how do you determine they're a cereus and not a stenocereus? I'm assuming you've decided they're not trichocereus due to the thinness of the ribs?
I just might try bio-assaying a stenocereus.

And D - what are the tell-tale signs of it being M. geomtrizans?

There already exists a good online guide for differentiating trichocerei. It might be prudent to compile all this information into an inter-species guide for distinguishing look-alikes of a different genus. Might do so myself, though I'm not sufficiently experienced to ensure I wouldn't be promulgating misinformation.

(by the way, all those cacti were found growing in public places within a city)

Cereus and Stenocereus are very easy to differentiate. Myrtillocactus geometrizans is a very unique cactus and easy to indentify.

Thanks to all who have replied.
So, I met with Plant B, properly introduced myself, and decided to take it home. I now have one 28cm cutting, plus the top 9cm, the growing tip, of the cactus (which will be given a good home with plenty of sunshine).
Now the conundrum: it weighs a little under 1.5 kg. From various descriptions I've gathered, this is unusually heavy for a 37cm cutting. It hasn't rained for at least two months, and the cutting diameter is not unusually large (8,5cm rib-to-rib).
Does this raise reasonable doubt as to its identification as trichocereus pachanoi?
Also, if hypothetically one were to consume the cactus, and this would be one's first serious psychedelic exploration, should the amount be significantly adjusted due to this weight? Sources cite ~0.12% as being the average percentage of mescaline in a fresh pachanoi, which would be quite a hefty dose for 1.5 kg (1.8 gram freebase [?] mescaline). Drying might provide a better measure of weight, but that would be problematic in my climate (coastal city - high humidity).

Of course not - would never do that. The cacti were growing in a public garden (in this case, in my university's campus, so I even helped fund its cultivation), and the cutting leaves the parent plant healthy and regrowing.
I did spot a huge potential trichocereus growing on private property, and I would certainly only take a cutting if permission were given.
