Perhaps you should try some spelling variations:
"monotypic taxon" » "genotypic taxon", "monotypic saxon", "monotypic faxon", "monotypic taxol", "monotypic tsaxon", "monotypic tfaxon", "monotypic taon"
"monotypic axon" » "genotypic axon", "monotypic saxon", "monotypic faxon", "monotypic aon"
"monotypic talon" » "genotypic talon"
"genotyping taxon" » "genotyping saxon", "genotyping faxon", "genotyping taxol", "genotyping tsaxon", "genotyping tfaxon", "genotyping taon", "genotypic taxon"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("monotypic taxon") OR ("monotypic axon"))) OR ("monotypic talon"))) OR ("genotyping taxon"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"monotypic taxon\") OR (\"monotypic axon\"))) OR (\"monotypic talon\"))) OR (\"genotyping taxon\"))".
• Removing quotes may allow a broader search: (((((( monotypic taxon ) OR ( monotypic axon ))) OR ( monotypic talon ))) OR ( genotyping taxon )).
• Adding a wildcard symbol may retrieve word variants: (((((("monotypic taxon") OR ("monotypic axon"))) OR ("monotypic talon"))) OR ("genotyping taxon"))*.
