I, too, have heard people advise abstention from placing new
names in titles. I suspect that this is a remnant of the
19th-Century dichotomy between American rules and International
rules. One aspect of the old American rules dealt with
page priority. Thus if a name appeared in a publication
prior to its description, e.g. on page 5 when the
description is on page 7, you have created a nomen nudum
on page 5. In the same vein is the decision of which
name to accept if two names are proposed in the same
publication but which later turn out to be synonyms.
The old American rules dictated page priority, i.e.
a name on page 36 had precedence over one on page 38.
I have heard American botanists still following this
rule today. It contradicts, however, the international
rules, which know nothing of page priority. It the description
and type designation are on page 7, and page 5 comes
off the printing press the same day as page 7, the
answer is no, the name on page 5 is not an entity
distinct from the validly published name on page 7.
