This botanical survey of the vascular plants of Washington County, Iowa was made in an effort to increase our knowledge of the vegetation of southeastern Iowa. Prior to this survey little botanical collecting had been done in Washington County. Sixty-eight specimens from Washington County were found by the writer in looking through the herbarium of the State University of Iowa. These were collected by the late Professor B. Shimek. The field work was carried on for a period of one growing season. Over 3,500 miles were traveled by the writer in making the survey. The first collections were made April 6, 1953 and the last October 21, 1953. 1600 collections were made, totaling approximately 3,000 specimens. A total of 677 different species of vascular plants are listed, 65 7 of which were collected by the writer.
