Thank you very much Lynn and Tara,
Lynn, you were absolutely right aboput the paddle segemented one. It is Rhipsalis elliptica! I just made 3 new hanging baskets and don't like selling things I don't know the name of!
That second thorny Cactus is very tough and rigid and almost woody. Its not neriifolia but it is close I'm sure. I believe it is a Euphorbia.
Tara;...It does have a lot of similarities to crown of thorns. Thank you for trying to help!
