The plants described in this article come from a locality three 

 and a half miles south of Banner City, Dickinson county, Kan- 

 sas. Three lots of plants have been collected— the first by 

 Mr. Sterling, of the University, in the summer of 1899 ; the 

 second by the author, in October of the same year ; and the 

 third, also by tlie author, in September of the present year. 

 The plants are preserved in an impure, more or less concre- 

 tionary limestone, sometimes grading into a sandstone. The 

 horizon bearing the plants is within about twenty feet of the 

 top of the highest Permian in that region, the hill along the 

 side of which the plants are found being capped with Cretaceous 

 sandstone. The types of all the species described are in the 

 museum of the University of Kansas. The specimens figured, 

 when not otherwise stated, are those collected by the author. 

 All discussion of the geological age of the formation, as well as 

 the extent and character of the plant-bearing horizon, is de- 

 ferred until the completion of the author's report on the entire 

 collection. The drawings and photographs are by the author. 



I am indebted to Dr. S. W. Williston for permission to work 

 on the Permian plants and for advice in the preparation of 

 this article. I am also indebted to Dr. David White, of the 

 United States Geological Survey, for advice and for personal 

 favors ; and to other officials of the U. 8. National Museum, for 

 access to paleobotanical library and plant collections of the 

 museum during a part of the past summer.
