I wonder whether it is time to pull the rug from under the feet of
Phylocode. Surely there are enough practising taxonomists who can point out
to journal editors that adoption of the Phylocode (even by a small part of
the community) will be a disaster and that editors have a responsibility to
discourage its use (by refusing to publish papers which adopt it). Most
library administrators will be pleased to have suggestions for saving money
by withdrawing subscriptiions to journals which are no longer regarded as
serving the interests of the scientific community. The proponents of
Phylocode can continue to amuse themselves devising unworkable systems on
obscure websites, leaving the rest of us to get on with life in the real
world.
