Abstract:
During the winter of December, the studies I am pursuing on the phytogeography of the deserts of the Northern Hemisphere led me to travel through the southwest of Arizona, the great expanse of Gila Desert, which American geographers have called the "Gila Desert," but which European maps generally call the "Gila Desert." I have already determined elsewhere the principal plant formations found in this part of the Great Basin, and I will only briefly summarize my itinerary here before giving a list of the plants I was able to collect.
