grasses and gondwana

[Ken Kinman]

Dear All,
     Following up on my last post.  It is interesting that some of the
closest relatives of true grasses (Poaceae) seem to be "graminoids" like
Restionaceae which seem to be southern forms.
     Could the true grasses and close relatives perhaps have been more
widespread than we previously realized (especially in the southern
hemisphere) during the Cretaceous?
     Any botanical biogeographers out there who could fill me in on this?
Perhaps gondwanatheres and early grasses evolved together in some way?
           ------  Thanks,  Ken
