Mayrose et al. (2011) and Arrigo and Barker (2012) concluded that neopolyploid lineages diversify more slowly than the diploid lineages from which they arise. We expressed concerns about this statement in Soltis et al. (2014a) to which Mayrose et al. (2014) responded. This article continues the discussion. We demonstrate a statistical problem with the original analysis which has not been discussed before. We point out that restricting to cpDNA data does not resolve the reticulation issue, contrary to Mayrose et al. (2014). Furthermore, we discuss some clade-specific problems with the data set used in the original analysis.
