Barrel cactus ID help

[gregc63]

Been wanting to use a nice stout barrel cactus with pink flowers and found these online. Any idea what this is?

Either Notocactus (Parodia) herteri or the plant often reduced to a subspecies under it = Notocactus roseoluteus, whose name means rose and yellow coloured, a reference to the flower. N. herteri usually has a more whitish centre to the flower. You will find them both listed under either Notocactus or Parodia which they were lumped into.
