First North Dakota flora checklist since 1963. The list is based mainly on three herbarium databases (many thanks to Shawn DeKeyser and Kathryn Yurkonis!) and also USDA PLANTS database. The last was especially useful as a source of synonymy and common names. Please note that cultivated and wild plants are not yet well separated. Nevertheless, if we estimate that we have ~ 150 cultivated plant species, state flora is still much more diverse that was previously thought — approximately 1800 species.
