During the past year an excellent paper on Iowa Pteridophyta, by Prof. Shimek, has appeared. This paper gives the distribution of the Iowa Pteridophytes as they are represented in the Herbarium of the State University of Iowa. The ferns as represented in our collection somewhat extend the limits and give additional localities of others. It is highly desirable that precise localities of our ferns be given, as it is a group of plants but sparsely represented in our Iowa flora. With few exceptions they are found only in favored localities.
