"but this cannot be extended to include all the flowering plants. Vast amounts of rapid differentiation and dispersal must have occurred in the post-Flood era, and facilitated variation theory can explain this."

More unscientific scientific tripe. This paper asserts that scientific observation must be wrong because it does not fit the young earth model. Maybe the young earth model is wrong. The author can argue theology or he can argue science, but to try to interweave both makes him look a fool in both cases.

and facilitated variation theory can explain this.

Can explain it?

Why not, "may explain it"? Or, "could explain it".

For as much bluster as I read about 'theory' not being fact, this guy's analysis is awfully short on conclusions.

It sounds like he's got a 'theory' of his own.

If the universal flood of Noah is true, would it not follow that rapid differentiation must have occurred since that time? All Alex Williams is saying is that now there is a biological mechanism that can explain the same.

Just out of curiosity, do you happen to recall Darwin's main argument for the “extreme imperfection” of the geological/fossil record?
