Mammillaria armillata?
Mammillaria eriacantha?
Mammillaria zublerae?
The last one is the only one I could find in this shape and yellow thorns.

I think you might struggle with this one Arif, it might not be Mammillaria but the circle of flowers is typical. There's a species list you can check ..

Mammaillarias Net . Janet you are correct, I will be busy for a looooooong time. Why are succulents so indiscriminate about breeding with whatever comes along?
Janet could you provide me the link for that Acacia look alike I might as well mark it done. I have not been able to find the silly thing.

Man helps indiscriminate breeding.

Here's your link Arif .. it's a good idea to post to say what it is as well.

The thread "Please ID these plants." in Plant ID forum

I did not understand what you were talking about. Ok. I will go post.
