occur downstream on private land adjacent to Spanish Fork (Stone 1993) . In 1993, these locations were revisited and the populations along the Diamond Fork River were found to be quite large (L. Gecy, RMI, in litt. 1994) . A small population has been located along the Provo River near Heber City, Wasatch County. A small population occurs at Willow Springs, near the desert community of Callao, Tooele County (Doug Stone, Utah Natural Heritage Program, pers. comm. 1994) . Four additional populations are known historically, but are believed to be extirpated. Specimens were collected in Ogden, Weber County, in 1887, but plants have not been relocated (Sheviak 1984) . In Salt Lake County, plants were observed in wetlands near the Jordan River as recently as 1953 and in Red Butte Canyon in 1966. Near the town of Panaca, Lincoln County, Nevada, plants were seen in 1936 in a wet meadow in the drainage of Meadow Valley Wash. Recent searches for these populations have been fruitless (Coyner 1989, 1990; Jennings 1989, 1990; U.S. Fish & Wildlife Service 1991; Stone 1993) . The population sizes as of the most recent census are shown in Table 1 for each watershed in which the Ute ladies'-tresses occurs. Table 1. Approximate population size of the Ute ladies'-tresses as indicated by the number of flowering individuals. Numbers are from the most recent censuses available for each watershed.
