Ive been contemplating it may be a senecio since it reminds me of a pickle plant. However, it doesn’t seem to want to grow upright and instead grows out and over (if that makes any sense).

I think it has areoles and real spines and not the spine mimics that Euphorbia have. You might be looking for pics in the wrong family. That looks a lot like a Pterocactus, to me, which isn't a Euphorbia. Is it P. tuberosus?

I don't think it is a Euphorbia. It appears to have areoles and spines which would indicate some species of cactus.

I'm not a Euphorbia expert by any means, but this looks more like a cactus because of what appear to be glochids rather than the typical Euphorbia spines. Any chance the nursery owners have a photo of blooms? I love ugly weird Euphorbias and hope someone can give a good ID.

Thank you to everybody. I searched for p tuberosus online and came across this website: http://cactiguide.com/graphics/p_tuberosus_a_600.jpg

The image from the Huntington library is spot on to what I have. I’m very excited now that I know what it is!! Thank you very much. I had never heard of a pterocactus prior to today.

I’m assuming this was a steal at $4!!! :-)

This website is so wonky...none of the other replies were visible when I posted. Is anyone else still having issues?

Yes, I saw that too, Liz. When I replied I thought I was the first but now I can see I wasn't. I saw only my reply for hours after I posted it.

Liz, I had the same issue. It had zero responses when I replied and now there are 3 before mine. It is always something on this site.
