[Taxacom] "Tenuinucelli" clade in eudicots?

Dear All,   
      Peter Stevens' APG Website lists one single character uniting
their large Order Ericales with the euasterids: ovules tenuinucellate.
However, Order Cornales (which I still place splitting off between them)
also have tenuinucellate ovules.  I think I remember a suggestion that
tenuinucellate ovules might possibly be produced by more than one
pathway, but if so, this seems to make such a character even less
      So is the sister group to euasterids (equal to my Subclass
Asteridae), the Order Cornales or the ericalean orders (APG's single
large Order Ericales, which equals my more traditional group of
Ericalean Orders)?  Is there any definitive evidence (either molecular
or morphological) that clearly answers this question?
