Thesis: Snow, N. 1989. Floristics of the Headwaters Region of the Yellowstone River (Wyoming), viii +116 pp.

This represents the thesis project by Neil Snow. Fieldwork was conducted during the summers of 1987 and 1988. The area encompassed the eastern Teton Wilderness, Washakie Wilderness, and extreme southeastern Yellowstone National Park (Fremont, Park, and Teton counties) for a total of 1,255 mi2 of mostly roadless area ranging in elevation from 5,950 to 12,156 feet. Collected were 5,600 specimens documenting 891 unique taxa. Much additional work is needed at high elevations. Species of conservation concern were not mentioned. Also vouchered were 62 exotics including eight noxious weeds. Funding was provided by the Shoshone and Bridger-Teton National Forests, a Payson Scholarship, the Wyoming Native Plant Society, and the University of Wyoming.
