Heads already took care of that in his comments.

John,
       So, what is your preferred hypothesis for how Bataceae came to
have its disjunct distribution?  [and perhaps you could name some of the
taxa with a similar distribution which you believe came to have this
distribution in the same way].

     This dispersal stories are not disconcerting at all. They are
empirically meaningless. If there is direct evidence of such travels
then ok, but to just make it up has no scientific merit as far as I am
concerned. When instead one sees extensive vicariism and comparable
ranges in both supposedly good and poor dispersers, along with
correlated tectonics, the imagined dispersal just becomes irrelevant to
understanding the spatial differentiation.
