This category contains the native flora of Maryland 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.

Include taxa here that are endemic or have restricted distributions (e.g. only a few countries). Use regional categories when taxa have a larger distribution that is approximately coincides by that taxon's distribution (e.g. Category:Flora of the Southeastern United States) instead of each subordinate category of that region.
