Can anyone suggest recent papers that address in any detail the idea that
clades that emerge in phylogenetic analyses of molecular data require
morphological or other non-molecular synapomorphies before it is practical
to recognize them formally?  I am particularly interested in commentary or
theoretical papers on this topic, rather than primary research papers in
which the topic had to be dealt with, though anything would be helpful.

Thank you for your help.
