Abstract

The original paper with this title, prepared in the late 1920's, was submitted for publication in 1932, and appeared in Volume 39 of the Proceedings of the Iowa Academy of Science. In the introduction to that list there was a brief description of the topography and of the natural areas of the county. It has not been considered necessary to repeat such description in this paper except to indicate some of the changes that have taken place since that time and which have affected the flora. The greatest changes, consisting of bringing the prairie under cultivation, draining most of the marshes and prairie ponds, and clearing and pasturing many woodlands, had most of them come by the close of the previous century, or shortly thereafter.
