Abstract

Astragalus iselyi and A. stocksii are described as new species. The former is from the La Sal Mountains of Grand and San Juan counties in eastern Utah, and the latter is from the Henry Mountains in eastern Garfield County, Utah. Yucca toftiae is described as new from materials collected along Glen Canyon in San Juan and Kane counties, Utah. Studies of plant collections taken from previously unexplored or little-known regions of Utah have demonstrated the presence of taxa not included in the known descriptions of plant species of the state. Two species of Astragalus and one of Yucca are included in the new entities. The La Sal Mountains and the Henry Mountains yielded the Astragalus species. The Yucca is from the margin of Glen Canyon.
