Stenocereus griseus?

Whatever it is, it is very healthy looking, and very nice!! :-)

I believe cactus Kate is on to something! In my book it gives it a rather antiquated genus: Cereus (Ritterocereus) griseus. It has probably been lumped into the Stenocereus clan since the date of publication on this book. I have seen these cultivated widely by cuttings.

I think Kate has nailed it.
I did a google with Steno... Griseus. Slight difference in the color of the spines at the apex, but I must agree.

Thank you VERY much!
