Relationship Between the Endophyte Embellisia spp. and the Toxic Alkaloid Swainsonine in Major Locoweed Species (Astragalus and Oxytropis)
A survey of the major locoweeds from areas where locoweed poisoning has occurred and found species found to contain the fungal endophyte and produce substantial amounts of swainsonine were A. mollissimus, A. cibarius, and O. sericea. Expand
Botanical and physiographic reconnaissance of Northern Yukon
The area of study is located in the northern panhandle of the Yukon Territory, and includes the British and Bam Mountains, Old Crow Flats, and the coastal plain of the north slope. The physiographyExpand
Endangered, threatened, extinct, endemic, and rare or restricted Utah vascular plants
The vascular plant flora of Utah is both large and complex, representing numerous floristic elements from many parts of North America, including unique and provincial elements restricted to the state. Expand
Taxonomic implications of diterpene alkaloids in three toxic tall larkspur species (Delphinium spp.)
The diterpene alkaloid content was used to assess the chemical taxonomic diversity in three larkspur species and support the classification of D. glaucum, D. barbeyi, and D. occidentale as distinct species and suggest that a possible hybrid is more similar to D. Occidentale than D.barbeyi. Expand
Distribution of Locoweed Toxin Swainsonine in Populations of Oxytropis lambertii
It is suspected that a plant fungal endophyte may be responsible for the high variability in swainsonine content in populations of O. lambertii, the major locoweed responsible for livestock poisoning on rangelands. Expand
On the distribution of Utah's hanging gardens
—This is a summary monograph of the hanging gardens as they occur in the Colorado River and Virgin River portions of the Colorado Plateau in Utah. Discussed in this paper are the hanging gardens,Expand
