Sorry, I have confused something. DIELS discussed D.*beleziana under
_D.rotundifolia_ (not _D.intermedia_). But still he did not believe in its
hybrid nature. On the other hand, he cited specimens of this hybrid from
Europe, so he obviously believed that such hybrids exist.

No need to apologize but have you talked about this with CROWDER, GRUBB &
LANGLOIS, already? They wrote (together with the Late M.C.PEARSON):
"The hybrid _D.rotundifolia * D.intermedia_ (=D.beleziana CAMUS) has not
been found in the British Isles. Our attempted crosses using both species
as pollen parents, were unsuccessful." (in J.Ecol.78:249, 1990).
Kind regards
