The map shows distribution within the Flora area symbolically, with each state × physiographic province area. The native/alien status of the taxon is shown by squares for native occurrence and triangles for alien occurrence. Note that some species have distributions including both alien and native distributions, so Dionaea muscipula for instance is native in the Coastal Plain of NC and SC, but alien in the Coastal Plain of FL and NJ. In the lower left and right corners are spaces that also provide distributional information. If the species is endemic to the Flora region, you will see "EN." If the species is alien, the region of the world to which it is native is listed in the species account, not in the map (as is the case in the PDF flora). If the species is native but not endemic, you will see a compass rose. Seven arrows depict the native distribution of the taxon outside of the Flora region. Arrows can be long (common at least somewhere in that region), or short (only uncommon or rare in that region).
The regions to which the seven arrows point are:
