I have this Mamm but dont know what kind, the photo is not that good (sorry) It produces tiny pink flowers in spring and summer and has hooked central spines that catch onto almost everything.
Thanks in advance
It's a mammillaria bocasana, you've got.
Hello Scott, Hugo is right, it's the pinkk flowered form of Mamm bocasana. You've got a nice clump there.
Here's a pic of one of mine...
