Abstract

In this study an attempt was made to collect all plant species growing on the Beaver Dam Mountains, and to arrange them into a workable flora of the area. A study was also made of the collections in the herbaria of Brigham Young University and Dixie Junior College. From this information keys and descriptions for all plant families and genera were written, as well as keys to all the species. For each species the following information was also given; the distribution in North America, the elvational range, period of flowering, and the location on the Beaver Dam Mountains in which the species was collected. Some 667 species in 308 genera and 78 families are recognized as occurring on this range. This study also shows extensions of the geographical range of many of the species of plants; as a result several new records for the state of Utah are listed. These are: Aloysia wrightii (Gray) Heller, epilobium nevadense Munz, Leptochloa filiformis (Lam.) Beauv., and Schismus arabicus Nees.
