Note: Synonyms are included in genus, specific epithet and infraspecific information pull-down boxes. If you search on a taxon name that is a synonym of the accepted name used by COLO, the records returned will show the COLO name. If your search is not returning any records, or is returning records that seem erroneous, check the Catalog of the Colorado Flora for COLO's accepted name and relevant synonymy.

*Search hints for Location and Collector Name fields:

  • use + (plus sign) before words to include all words in your search results (equivalent to the AND boolean operator): +black +canyon
  • use " " (double quotes) to search for an exact phrase: "Rocky Mountain National Park"
  • use - (minus sign) before words to exclude words from your search results (equivalent to the NOT boolean operator): -boulder +mountain +park
  • use of no symbols will retrieve records with at least one of the search terms (equivalent to the OR boolean operator)
  • keep search more general to capture all desired records; e.g., a search on 'Ramaley' will return records that contain 'Francis Ramaley' and 'F. Ramaley'; a search on '+Verde +Park' will return 'Mesa Verde National Park' and 'Mesa Verde Nat. Park'.
