33. Map source issues
If I go to Acer floridanum and remove all data sources except the three from NCU, or all except UNC-Acer barbatum and NCU-Acer saccharum and redraw the map, every county without a specimen turns yellow, even those with no records at all. Also, for this species Legend shows NCU-Acer barbatum, but not NC-Acer floridanum. A similar problem on sources occurs with Carya glabra where only 2 of the 3 NCU databasing options shown on the Legend but all are in the data source menu. Must be a couple programming errors here.
