This category contains the native flora of the former country Czechoslovakia as defined by the World Geographical Scheme for Recording Plant Distributions. Taxa of the lowest rank are always included; taxa of higher ranks (e.g. genus) are only included if monotypic or endemic.

This category is a geographical, not political, circumscription.

Include taxa here that are endemic or distributions restricted to the current Czech Republic or Slovakia. Use regional categories when taxa have a larger distribution that is approximately coincides by that taxon's distribution (e.g. Category:Flora of Middle Europe) instead of each subordinate category of that region.
