Individual Plant Species or Groups of Similar Species

In November, 2015, we have begun putting distribution maps online for some species, whenever they pique our interest enough that we wanted to see a map for ourselves. Those maps will either be linked from the species page, or will be given as a separate link for each family.

The distribution maps may be made from our GPS point database, or from vouchers, or from both.

For an overview of our GPS point database, and maps showing where we have processed records, see Geographic Distribution Maps of GPS Points for Plant Species.
