Excerpt from Across Papagueria
In the preparation of a résumé of The Botanical Features of North American Deserts (publication No. 99, Carnegie Institution of Washington) it became apparent that systematic information on the general features of this region was very meagre, and an expedi tion from the Desert Laboratory was planned which would traverse a route from Tucson to the Gulf.

Excerpt from Across Papagueria
The Pacific coastal desert of North America extends from the region of the isthmus of Tehuantepec northward to include the peninsula of Baja California and a part of Upper California. To the eastward one broad arm spreads out from the shores of the Gulf of California to include nearly all of Sonora, the southern and western part of Arizona and the southern part of Nevada, in which regions it joins the higher bolsons, mesas and basins of Chihuahua, New Mexico, Utah, Nevada and California. The entire region is one of great aridity, and probably no part of it under 4,000 feet in elevation receives more than 12 inches of rainfall annually; the ridges and peaks which rise above this level may have three times as much, by the condensing action of their summits. On the other hand, the great area lying to leeward pf the main peninsular ridge of Baja California and its northward continuation in California, are so situated that the annual precipitation is often as low as 2 1/2 inches per year, while many localities receive no rainfall over periods as long as eighteen months, as noted by Palmer with regard to the Raza islands in the Gulf of California.
No adequate natural history survey has yet been made of any portion of this region. The Boundary Survey Commission traversed the northern part in demarking the southern line of Arizona, the most arbitrary and meaningless political boundary in America, and made collections in the immediate vicinity of the line, but the nature of the work did not permit any attempt at studying the general relations of the life of the region, although much detailed information was procured as to the composition of the fauna and flora.
