But homonyms may not be given equal precedence under the Phylocode:

"13.3. If two or more definitions have been established for identical=
ly spelled
names, the only acceptable name (i.e., the combination of name and de=
finition;
see Note 12.1.1) is the first one established under this code. A late=
r homonym,
unless conserved, is not an acceptable name of any taxon."

Thus, if _Ficus_ were defined using the the snail species, any later =
attempt to
define a clade named _Ficus_ using the fig species would not be accep=
ted
(unless conserved, in which case the snail-based taxon becomes unacce=
pted).
