Taxon Locations

I've posted two spreadsheets that show state or province postal codes for all FNA terminal taxa.  Due to a Google Drive spreadsheet size limitation, these data were split:  Alberta through North Dakota and Nebraska through Yukon Territory.  Taxon counts by location are in the last row.

Terminal taxa  in my taxon list (see Taxon List & Counts by Type) have locations shown on their FNA taxon page.  The 11,200 terminal taxa that have their own taxon page have the following location information:

Location directly shown on taxon page	11,148
Location indirectly available	50
Location information not available	2

Indirect location information is most commonly found from a distribution map.  One of the taxa (Iris germanica) with no location information says it "may persist after cultivation"; the other (Corispermum nitidum) says it was "supposedly introduced but doubtful".  Location information for the few taxon without their own page has not been added yet.

The 65 North American locations used in the FNA are the 49 continental states and District of Columbia in the USA, the 13 provinces and territories of Canada, Greenland which is an autonomous country within Denmark, and the islands of St. Pierre and Miquelon which is a self-governing territory of France.

In the future, if a user of the FNA keys selects the location(s) that they are interested in, then the keys can be customized.  Then the keys would only show those couplets and terminal taxa relevant to their location(s), which greatly simplifies keying a specimen. Also the keys can be simplified because there are location-specific couplets in the keys; these couplets may eliminate all except one attribute set leading to the terminal taxa.
