Category:Flora of Northern America

For the purposes of this category, "Northern America" is defined in accordance with the World Geographical Scheme for Recording Plant Distributions (WGSRPD), namely as one of the nine "botanical continents". It includes the following regions:

Flora of the United States (including Flora of Alaska and Flora of the Aleutian Islands, excluding Flora of Hawaii)
Flora of Canada
Flora of Mexico
Flora of Greenland

The WGSRPD defines Northern America differently from the usual geographical definition of North America. Central America and the Caribbean are treated as part of the botanical continent of Southern America; see Flora of Central America and Flora of the Caribbean. The flora of Hawaii is included in Flora of the Pacific.

Native taxa of the lowest rank are included if they occur widely in the botanical continent, otherwise they should be included in the flora of one or more of the constituent regions. Higher taxa are included only if endemic.
