This survey brings together the available information on the flora of ten northwestern Iowa counties-the species of vascular plants occurring in the area, their relative frequencies, and the habitats in which they exist. The major collecting was done throughout the growing seasons of 1956 and 1957. Over 4,000 collections were made, and the probable number of specimens is over 9,000. The author examined and annotated over 1,100 specimens which had been previously collected and deposited in the major herbaria of the state. Plants characteristic of several of the typical plant communities are listed.
