It's a Sulcorebutia/Rebutia.

Thanks, Jeff. Had a feeling it wasn't a Gynmo. Now, for a species.

That's the one I have that I couldn't identify. Amazing flowers. Rebutia? really? Go figure. I thought it was a gymno too.

Here's a picture of the body... might be helpful...or not.

Probably needs a slightly larger home, yes??????

Howard

I'm thinking Lobivia arachnacantha.

Wow Howard, the color of those flowers is just breathtaking!

And yes, I think it needs a new home. Looks a little tight there, haha.

Planto

It looks like lobivia arachnacantha to me too..

Isn't the dividing line between Lobivias/Rebutias&Sulcorebutias the difference in size (both body and flower), fairly basketballish plant-size-wise on the Lobivia side and diminutive on the Rebutia/Sulco side?

Jeff, you've gone way past my "need to know".....LOL And thanks.

Who knows where the dividing line for Rebutia is? It's apparently polphyletic according to some multigene phylogenies done about a decade ago. All sorts of stuff mixed in there...
Here's a tree and a 2007 paper from amjbot below.

Here is a link that might be useful: phylogenetic placement of rebutia etc.

Lol. How's that for too much info?

It appears it is Lobivia Arachnacantha! I was looking at all the gymnos to identify mine. I was looking for Lobivia in all the wrong places....

Ming,

I dinna ken, lass. You give me too much credit. Like Sollazzo said in 'The Godfather', I'm not that smart.

Shhhh!
