Thanks for your help Alan I

Thanks for your help Alan I couldn't find any translucent dots on the leaves which is why I hesitated, is this hybrid fertile?

Depends how you define fertile.

It produces seed and builds up large populations, but as the perforatum/desetangsii complex is at least partly apomictic, this can be without fertilisation. I don't know very much about this in Hypericum. There is a guy working on them.

Google found me a D.N.S. thesis (2011) ...

... by Charlotte Luise Scheriau on "Evolutionary history of Hypericum perforatum L.". It all looks rather messy - diploid, tetraploid and hexaploid cytotypes of H. perforatum, and diploid and tetraploid cytotypes of H. maculatum before you even start on the hybrids.

Thanks for the comments and

Thanks for the comments and information, now that I'm sure of the ID I can see that we do have large populations of this hybrid on the roadside verges
Thanks for the on-line thesis I also found Genetic Diversity in Hypericum and AFLP Markers for Species-Specific Identification of H. perforatum L
Looks rather complex!
