Total number of plant species, by country

Note, this dataset was collected between 2017-2020 from several academic sources. For some countries, the estimates are significantly lower than the World Conservation Monitoring Centre's 2004 aggregation (WCMC), which in some cases included multiple synonyms for a given species. The top table is considered more accurate, but the WCMC is also included as the second table..

The data agree that Brazil has the most plant species of any country, but after that, the rankings differ. But even with that caveat, the lists of the top 5 countries in terms of plant biodiversity share four names: Brazil, China, Colombia, and Mexico. Of the top 10 for the number of plant species, the lists share 7 countries.
