Interpretive Summary: Amsinckia species are poisonous plants that cause liver disease in animals that eat too much over a period of time. The common name for Amsinckia is fiddleneck because the flower head is shaped like the neck of violin or scorpion’s tail. In the literature there is much confusion and misinterpretation of the taxonomic description. Therefore, this manuscript narrows the large number of taxa described by other botanists to 11 specific species with taxonomic descriptions. The impetus for this manuscript came as a result of a poisoning case in cattle in Arizona.

Technical Abstract: An overview and taxonomic re-evaluation of the Amsinckia genus as it is presently known in the western United States is provided. Because of the confusion and mis-information about the classification of the Amsinckia speces in general and as a result of a cattle poisoning case in Arizona, it was very timely to re-visit the taxonomy of this genus. In this review the hundreds of segregate Amsinckia species provided in the literature historically is narrowed to eleven species and an additional 6 infra specific taxa.
