Pilosocereus ID

[Spikylover]

Hello everyone
I saw this pilosocereus at the nursery and i'm wondering: Is it pilosocereus calcisaxicolus? It looks a lot like it but not completely similar.

Bonus question, i'm almost sure this is pachycereus pringlei but it is very short and fat. My pachycereus pringlei look more like a baseball bat. Could these be saguaros?

I tend to stay away from pilosocereus identification but you could be right, although the name could be P. Flexibilispinus. P. Gounellei is also an option
As for the other cacti, the red spines point towards Pachycereus pringlei. Most of mine look like a "baseball bat" as you say but i do have one that is short and plump. Their spines look very weak compared to what they should look like.
Btw, could you please send me a PM with the location of this nursery? They look like they may have interesting specimen

I tend to stay away from pilosocereus identification ..........

Me too Elie .... especially for seedling or juvenile plants - the plant structure, spination, rib count, indeed the overall aspect of most juvenile Pilosocereus is often so very different from mature plants that attempting to ascribe any kind of meaningful attribution to photos of juvenile plants is mostly a WAG (Wild ... Guess). To me, meaningful attributions of cultivated Pilosocereus (and most other columnar genera such as Micranthocereus, and Coleocephalocerues) can only be rendered by observing mature specimens in flower and fruit - in addition to stem structure and spination.

I would guess P. gounellei - but that is a guess, I'm no more confident in IDing those than Elie and James are.

I'd say in this case P. calcisaxicolus is correct. I don't know much about this name. It seems it's only known from a single HU number.
