Convention 9.—A taxon of hybrid origin will be indicated by placing the names of its parental species in parentheses beside the taxon's name. If the taxon is placed beside one of the parental taxa, its sequence in a list carries no connotation of branching sequence relative to taxa of "normal" origin. Wiley (1981a:226-227) suggested that hybrids between species in different genera should be placed in a third genus. This is not necessary, but you should not place the hybrids in both genera if you do not wish to name a third genus because it might cause confusion regarding the actual number of species that exist. There are several ways this convention can be used. One way is shown in Fig, You might also tiy listing the hybrid taxa under, say, the genus name and then proceed with the species of nonhybrid origin using other conventions. /./ ^- ^^- ^- '^^^ '^^ \^ 0^' . /.
