Hi Jim,
      I am not sure what you are saying.  Are you saying that
Pteridophyta is polyphyletic, rather than paraphyletic?  If so, can you
quote some papers which present evidence of its polyphyly?

When someone utters the name 'Pteridophyta', most people have an idea
what they are talking about, so in that respect it is not meaningless. 
 But to use the same handle as a statement of origins, relatedness and
connectedness it is not only uninformative, it is misleading.
Communication is all about context.
