Picea hybrids

A very simple question: Does anybody know of hybrids between Picea pungens and P. sitchensis?

I am trying to identify specimens from cultivated and subspontaneus populations of conifers in southern Sweden and I have then found specimens that appear to be intermediate between these two species in needle characters (i.e. slightly flattened needles with 2-4 complete rows of stomata on the upper surface and 6-8 rows of stomata on the lower surface). However, I have not been able to trace any such hybrids in the litterature and I have no experience of the natural variation of these species in native populations...
