FLORA OF THE STANSBURY MOUNTAINS, UTAH

Alan C. Taye'

Abstract.— The Stansbury Mountains of north central Utah rise over 2000 m above surrounding desert valleys to a maximum elevation of 3362 m on Deseret Peak. Because of the great variety of environmental conditions that can be found in the Stansburys, a wide range of plant species and vegetation types (from shadscale desert to alpine mead- ow) exist there. This paper presents an annotated list of 594 vascular plant species in 315 genera and 78 families. The

largest families are Asteraceae (98 species), Poaceae (71), Brassicaceae (33), Fabaceae (27), and Rosaceae (26). Elymiis flcwescens was previously unreported from Utah. Statistical comparison of the Stansbury flora with neighboring mountain floras indicates that the Wasatch Mountains lying 65 km to the east have probably been the primary source area for development of the Stansbury flora. Many lowland species, especially those inhabiting sandy areas, apparently have migrated to the area from the south.
