There is no doubt better place here to post my apologies for dropping out of at least several conversations the last few months but time is not something within my control. I'm hoping to get that addressed soon and catch up.

I wanted to make a post that the San Pedro book is online as a PDF. The book was printed in black and white but it was never a black and white work. I think a lot of people will enjoy seeing this.

There was some weird glitch for me I could not figure out involving some of the images on three pages so I put copies of those at the front until I can resolve what is occurring.

Keeper Trout: Thank you for this important and valuable book

Much appreciated! I'll be spreading your link

One more excellent contribution to the community! Thank you very much for this amazing work!

Thank you very much, Keeper Trout. Highly appreciated.

I'm liking the information... Been wondering about T. validus (waiting on 2 cuttings of "Trichocereus validus? NL52509a" now).

2 Questions:

Is "Trichocereus validus? NL52509a" white-flowered?

Can you please link me to a vendor/collector offering confirmed "Trichocereus validus (Monville) Backeberg" ?

Validus should have white flowers yes.
I think SS has some reservation on Neil's ID.
Bona fide is a curious question to try and answer since the description is seriously in need of help.

One comment Backeberg made that seems pertinent is that validus as he knew it had not been observed to branch but he assumed it could. There are some of these that do not branch even at 9 feet tall. Does that make those that don't not validus? I do not know.
I do assume that Echinopsis forbesii and Trichocereus pasacana inermis and Trichocereus terscheckii inermis are synonymous with T. validus but not all E. validus are synonymous (for isntance the short clump former with pink flowers is clearly something else - probably something mislabeled but sadly entering seed production channels.)
All that can really honestly be said is validus needs more work to define it based on a wild population. Maybe Neil found one? Time should be able to tell.


Thanks everybody for all the nice comments.
