During the growing season of 1938 the opportunity to collect plants of the central section of southeastern Iowa was made possible. This flora is of importance because it represents the significant floristic features of the southeastern quarter of the state. Since its purchase from the Indians 97 years ago, there has been a very definite change in the floristic aspects of this section of Iowa. This change is still taking place and is resulting in the extinction of some of the native plants in the region. However, many of these plants are still to be found in Mahaska County, although they are fewer in number than formerly. The chief purposes of this work were to ascertain as fully as possible the flora of the county, to bring up to date the names of the plants treated in this survey, and to point out possible floristic changes in the county.
