That website is organized poorly - too much "drilling down" to get to what

Here are the relevant URLs for those not into exploring. Click the big "PDF"
button on each page to view the content.

2) Rebuttal by William Anderson: TAXON 56(2)

3) Rebuttal by Wesley Higgins and David Benzing: TAXON 56(3)
