Perhaps you should try some spelling variations:
"monotypic faxon" » "genotypic faxon", "monotypic saxon", "monotypic fanon", "monotypic taxon", "monotypic fsaxon", "monotypic ftaxon", "monotypic faron"
"monotypic axon" » "genotypic axon", "monotypic saxon", "monotypic taxon", "monotypic aron"
"monotypic danon" » "genotypic danon"
"monotypic aon" » "genotypic aon"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"monotypic faxon\") OR (\"monotypic axon\"))) OR (\"monotypic danon\"))) OR (\"monotypic aon\"))~".
• Removing quotes may allow a broader search: (((((( monotypic faxon ) OR ( monotypic axon ))) OR ( monotypic danon ))) OR ( monotypic aon ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("monotypic faxon") OR ("monotypic axon"))) OR ("monotypic danon"))) OR ("monotypic aon"))*.
