A field survey of Warren County made during the months of April, May, and June of 1962 identified over 200 collections of flowering plants. During the fall of 1962 a survey of the Red Rock Dam area identified over 50 collections of flowering plants. Simpson College Herbarium specimens of these areas were carefully checked and annotated. In these collections, 17 species were found that had not been previously published for these areas.
