Totals: 469 species (202 native, 267 non-native to area).
Nomenclature is per Gleason & Cronquist, Manual of Vascular Plants of Northeastern United States and Adjacent Canada - Second Edition (N.Y. Botanical Garden, 1991).

An "AN" indicates that the species has been introduced into the region from someplace other than the remaining continental United States or Canada, and is to some degree naturalized here. An "NN" indicates a North American species that was not originally native to the region but which has been introduced and naturalized here from someplace else in the continental United States or Canada. An "AO" after an entry indicates that the species is alien and occasionally found growing without cultivation, but is probably not truly naturalized; this is a catch-all category for a variety of garden escapes and marginally persistent or very local introductions. An "NO" indicates a species that is not native to the region but is occasionally introduced here from elsewhere in North America, but is probably not naturalized. Where no letters follow an entry the species is native to the region and is believed to still be present.
