Well it's obviously no ordinary Bridgesii. But I'd say it leans more on the Bridgesii side. Since these are sort of mystery cuts, you can't really be sure. Although the only other cactus I've seen long spines like that have been on macrogonus.. Cut a little piece off the end and taste it, see how bitter it is.

I bought these three at a Home Depot a few days ago. They were labeled as Trichocereus species. The flowers have dried up but it looks like they were yellow. Trichocereus grandiflorus? Some kind of hybrid?

 

I want to try eating a little bit to see if it tastes super bitter like pachanoi, is that a bad idea?

@Clammus I don't think those are real flowers. They are corn flowers that have been hot glued to the cactus, eventually they will fall off. And yea, Fresh brewed got it, those are grandiflorus or some form of grandiflorus hybrid.  You should be able to find out what cultivar after they flower for real.

Hi all! Could I please get an ID on this enormous cactus I happened upon in a yard in SE Florida? The pics are all of the same cluster from different angles, including a pic of the babies on the sunny edge (seedlings or clones?).

The application of your expertise will not go unappreciated ;)

Oh shoot, are those pics annoyingly large? Let me know and I will resize. I'm on an iPhone so hard to tell but I think they're big files.

Not 100% but I think it's a "Cereus hildmannianus". Very popular cactus with amazing flowers.

 

It's definetely a Cereus.

 

Edit: Comparing your pictures with google results for "Cereus hildmannianus" I think it's indeed that cactus.

I do have one source saying the Cereus hildmannanius has eight vertical ribs. Now even on some of those very thick, old, tall columns - six ribs max. Many were four-ribbed.

I am not claiming that it's a cereus hildmannianus, Cybilospin...

It's just a guess =).

 

But...

 

Your source is wrong.

C. Hildmannianus has indeed 4-6 ribs, produces very short to none spines and can get massive. (Source: Edward F. Anderson)

All of this is true with the cacti in your pictures.

 

But...

 

I am not an Cereus expert!

It's still only a guess, but not an 100% identification.

Many other cacti genus can have a huge variety depending on their location. There are san pedros for example who look like bridgesii because the specimen growing on higher altitudes make much longer spines. Same for many ariocarpus and lophophora, where form and flower color can drastically change just because of their location.

 

Hope I could help you a little bit

Hi everyone !!
 
Please, someone can recognize those cactus ?
 
First one could be a pachanoi ? I bought them at La Paz (Bolivia) on "Calle de las Brujas" street
post-114145-0-76891500-1454383724_thumb.
 
Last one could be a peruvianus ? I took them from "La Isla del Sol" at Titicaca lake in Bolivia

Thanks a lot !!

No Pedros on both pictures. The cacti on picture two look like 15+ year old Trichocereus Peruvianus to me also.
And the cacti on picture one look also like T. Peruvianus to me, but it's also possible that you have T. Bridgesii instead judging by the spines.

Edit: A sharp close up pictures of the spines could help a little bit.

Hi Neptunechild ..

thanks for your response !!

 

Here is a pic from first ones (pachanoi) years ago

pedros.jpg

 

 

Both cactus got more than 10 years old

 

Someone told me years ago this .. 

 

Trichocereus peruvianus is Torch
Trichocereus pachanoi is San Pedro
Trichccereus brigesii is Bridgesii

 

Is it correct ?

 

Thanks in advance !!

Weird how long spines they have produced ove the years. Do I guess right that you live at higher altitudes?
San Pedros spines get longer the higher the altitude is they are growing on, so maybe that's the reason why they don't look like typcial pachanoi.
Can't help more then this...after seeing the young cuttlings, it may be indeed pachanoi after all!

Yes Pachanoi is San Pedro and Torch is the Peruvianus.

Maybe it is because high moisture ?

What do you think about this extraction method ?
