Abstract

The territory within which botanical collections have been nmade in connection with the United States Geological Survey of the 40th Parallel lies wholly within the limits of Northern Nevada and Utah. It forms a narrow tract at no point exceeding seventy miles in width, between the meridians of 111° and 120°, and extending frorn the parallel of 39° at the southwestern limit to that of 42° at the northeastern. This region constitutes the northern portion of what was at first designated as the "Great Basin" the high plateau, without outlet for its waters, separated on the north by low divides from the valley of the Snake River and continuing southward until it merges into the desert of the Lower Colorado. Geologically considered, however, as well as botanically, the term is now properly made to include the whole similar arid stretch of country northward to the plains of the Columbia in latitude 48°.
