Dear Muad'Dib,
No, D. rotundifolia * D. linearis is not fertile. Neither are any of
the crosses of these species with D. anglica.
However, you can make these hybrids and many more with these and other
closely related species, but all the these hybrids are not naturally
fertile.
Well, D.anglica does make seed. I'm am not sure if has a pollinator or
if they always self-pollinate...
