Cactus ID Please

Hi, I recently obtained this specimen and while it looks common enough it came without a label.

Could someone please help me out with a positive id?

It must be self fertile as it produced two large fruit, packed full of seed, and I only have the one specimen in my collection.



As you can see it has yellow flowers with pink centers and it flowered profusely forming a ring or crown of flowers, with several open at once, very attractive



Thanks for any help

Most likely Parodia mammulosa. Looks like you had quite a display of flowers on this one!

Thanks Lachy.

I googled Parodia mammulosa and although some examples looked quite similar, alot were noticably different.

So I'm still not certain.

Any other takers?

Looks the same as my mammulosa.

Thankyou too MichaelCactus, for helping confirm the ID.
