British Columbia plant species codes Version 14 (2020)

These species code files contain the presently accepted scientific and common names for vascular plants, mosses and lichens of British Columbia . The liverworts and hornworts included on this list are from the North American lists as a B.C. list does not exist. All species are given a 7 or 8 character code for use in database applications. In addition, commonly used species synonyms are included to assist in determining the presently accepted name.

Changes to this list are the result of an annual review of nomenclatural issues, herbarium review, and reports of new species to BC by the BC Flora Expert Committee. Further description of these changes and species as at risk rankings can be found at BC Species Explorer
