Mystery Gymnos

[Sahara]

Please help! I have these gymnos and i don't know what they are.

The first one came labelled andreae, but i'm not sure that's quite right. Any suggestions?

And the second one I think might be a young saglionis, but I don't have the best track record with these things.

The first one isn't G. andreae. It might be some form of G. anisitsii.

The second looks like G. pflanzii, another big one like G. saglionis but not quite so big and not quite so many spines. The flowers tend to have a pinkish tinge where G. saglionis are more grey.
