"ex" in authorship was: "fide" in authorship

This is really rather simple: The tradition has been that if, say, a
monographer of a genus publish a major work (which would be authored
by the monographer), other workers on the same group could be invited
to publish their new species there (and still be the formal author of
the name) rather than in works of their own. These names would then
by clear cases of "in". The same goes for co-authored names in
single-authored books and papers. If, however, the monographer would
find a specimen of a previously undescribed species in a herbarium,
that another worker had given an unpublished name, the monographer
would often acknowledge this by using this name and attributing it to
this other worker (a case of "ex"). The author of the name would of
course formally be the monographer, thus "Smith ex Jones" is
shortened to Jones.
