Dear Todd,

Philodendron is a neotropical genus (occurs from Argentina to Mexico) and
have basal female flowers, fertile male flowers (apical) and sterile male
flowers (intermediate) on its spadix. Despite of the resemblance of their
growth forms, Raphidophora is a Southern-Asian genus (I think it occurs
along India, Java, New Guinea, etc) and have only bisexual flowers on its
spadix. They are quite different to be synonimyzed! I'm not sure if 
_Raphidophora decursiva_(Roxb.)Schott is still valid, but I think it is. 
Peter Boyce has been working with epyphitic vines from the paleotropics 
and I suppose he can help us. 

                            Best Wishes,

Eduardo.
