First photo - plant on right is Cleistocactus strausii.
Second photo looks like Pilosocereus tillianus.

Thank you. Yes, they definitely look like the pictures I'm seeing on the web. I need to study the whole thing more. There's an entry in Plant Files for a P. lanuginosus var. tillianus, is that the same plant?

If so, maybe PF should be updated. The Kew Plant List has P. tilianus as an accepted species name (and I learned it comes from Venezuela).

Baja,
As of 2001 per Anderson's book, "The Cactus Family", P tillianus is a synonym of P. lanuginosus. And after being taken a step further, is a variety. Now unless Hunt's 2007 book "The New Cactus Lexicon" has it listed other than a synonym of P. lanuginosus, then it is correct.
Does anyone know how it is listed in TNCL?

The first one in the first photo is some type of Ceroid. I've been browsing these albums here for Columnars:
