 When you say that Corydalis is a "valid genus name", does that mean that
some
 of the Corydalis kept that name but others, like C. lutea changed to
 Psuedofumaria lutea?  or would C. sempervirens now be P. sempervirens also??

 Are synonyms still considered valid genus names that just aren't used
 anymore?   Does this database also have an entry for each species?  And
 finally, does "taxon" mean the 2-part name of genus and species?  LOL, after
 all this, I hope I don't end up dreaming about taxons, synonyms and nomen
 numbers!

Yes Corydalis was broken up into a few diffrent genera, I do not remember the
other species in Psuedofumaria, I believe I posted them a number of months
back (Do we have archives)

Corydalis had well over a 100 species, with many being annuals or Biennials.

North America has a number of different species on both sides of the
Mississippi, On the Eastern Side we have 6 species that were placed in
Corydalis, they had there own Genera  Capnoides, which is not used any more.

I do not know the bases for the name change, but it is not hard to tell that
P. lutea is somewhat diffrent than the other taxon that are in Corydalis.
There is that word taxon.

Taxon is just a group of plants grouped under the same name.
Species would be a taxon of interbreeding plants with genetical uniform
heritably traits.

Genus would be another taxon and so would Family and subspecies too.

I hope that did not make it more confusing.

<<Are synonyms still considered valid genus names >> synonyms are not valid
names, but this is scientifically speaking, what "normal" people do with a
name is a diffrent story.

A name is only as good as it communicates what the plant is, until that name
is commonly used, both the valid and the unvalid name may be used in
conjunction with each other.
