Asyneuma or not Asyneuma?

Got this as Asyneuma limonifolium - but the flowers look wrong.
is it Asyneuma or some other Campanulaceae?

I think your plant is Campanula speciosa, from the look of the basal rosette.  If you scan through the photos in the attached link, some of the flowers that are said to be Campanula speciosa also resemble yours:

I don't believe your plant is any species of Asyneuma. 
BTW, I have been sending seeds of Asyneuma limonifolium to the SRGC and NARGS seedexes for some years, and will likely do so again in the coming season, if that's something you take part in.  Here's what my plants look like - the taller form is about 6 inches:

Showed the plant at bakewell show yesterday and was advised it is Campanula aizoon - or at least 'aff. aizoon'.
At least we got the Campanula right!
