Classifications

[Ken Kinman]

Susanne,
     In my classifications, paraphyletic groups are already shown explicitly
by the presence of outgroups markers, so my main motivation in specifically
marking the taxon name itself is especially for use in text where the
outgroup marker would not appear.
     Quotation marks are so widely used for other purposes in text that such
a convention could be too confusing in many contexts.  Therefore, I prefer
something distinctive, and since % is usually used in combination with
numbers, its use attached to taxon names would be very distinctive.  I chose
double brackets for markers for the same reason.
         ------ Cheers,   Ken
