Philodendron radiatum and P. elegans are distinct species but
admitedly they are similar, with the later being smaller, having fewer
divisions and drying darker. I am not sure about the flowers because I have
not compared them.

A few answers for your questions:
1. Yes, Philodendron melanochrysum is the same thing as P. andreanum. They
were described for the same plant, adult and yong. As far as I remember, P.
melanochrysum is the name to be used.
2. I checked the only reminescent of Koch´s material of Philodendron selloum
and it is the same as P. bipinnatifidum, as Mayo noted almost 10 years ago.
However, there are two species commonly traded as P. bipinnatifidum, that
are P. lundii and P. mello-barretoanum. There will be an article I wrote on
this subject (P. bipinnatifidum complex) for the forthcoming Aroideana.
3. It is possible that P. radiatum and P. elegans are the same thing. I
think Tom Croat already checked on it before. (Any commnets, Tom). The other
two species (P. tortum and P. distantilobum) are well distinct and
recongizable. I have not seen P. pinnatilobum.
I hope it helps,
