Maps automatically open at the center of the plotted points and the scale is set to encompass all map points. Maps can be resized (scale bar at upper left) and the center moved (place cursor over map and drag) to see other parts of the distribution of the species. Clicking on a map marker will pull up collection event data and a literature citation if present. If any errors are found, please refer to the "series code" which is a unique identifier for a database record in any communications). Coordinates have not been entered for all collection records. Localities outside the New World are not plotted, even though they are listed in the distribution summary and in the table of records.
