The Faculty of Agronomy and Forest Engineering at Pontificia Universidad Católica de Chile have a herbarium (a collection of preserved plant specimens) for the country of Chile which were collected along different vegetation regions in Chile. Someone named John Acuña, and undergraduate at the school, has produced a Google Earth file which shows you the locations of the herbarium specimens along with other information. From the post at the Google Earth Community:
Each icon, represented by a “Palma Chilena” (Jubaea Chilensis), shows one or several collection points with information about the scientific name, botanic family, geographical location and other interesting links…. This kml file is a part of the final work developed by John Acuña, undergraduate student in Forest Engineering, under the supervision of professors Marcelo Miranda and Miguel Gomez.
