Arthur herbarium at the Purdue Experiment Station. An attempt has 

 been made to show the distribution within the State by counties. Under 

 each host is given a list of the counties within which the species lias been 

 collected, together with the name of the person making the first collection 

 and the year in which the collection was made. A considerable number 

 of the collect ions which have been recorded in thefirsl lists were not available 

 to the writer. These have been included in the distribution only when there 

 seemed to he no chance of mistaking their identity. A few species evidently 

 wrongly determined of which no specimens were available, have been omitted. 



The nomenclature followed is that of Dr. J. C. Arthur as used in the 

 N. Am. Flora, volume 7, in so far as that admirable work has been com- 

 pleted, or as proposed for the unpublished portion. The nomenclature of 

 the hosts in general conform to that of Britton & Brown, Illustrated Flora, 

 2nd edition. 



For convenience in consulting the list, the species not previously recorded 

 are marked *. Hosts not previously recorded are printed in black-faced 

 type. References are inserted following the host name to the year and 

 page of preceding volumes of the Proceedings, where additional information 

 may be obtained. Wherever Indiana rusts have appeared in published sets 

 of exsiccati reference is made following the collector's name. Reference 

 by number is made to the rusts included in the set of Parasitic Fungi dis- 

 tributed by the Indiana Biological Survey. December, 1894. Series 1. (See 

 Proceedings 1894:154-156. 1895.) 



It is the plan of the writer to submit additions and corrections to this 

 list as material is collected. It would be greatly appreciated if collectors 

 would send duplicates of their collections to the writer. 



The. writer wishes to acknowledge his indebtedness to Dr. J. C. Arthur 

 for the unrestricted use of his hei'barium and notes in the preparation of this 

 list without which any approach to completeness would have been im- 

 possible. Dr. Arthur has also kindly read the manuscript and offered many 

 helpful suggestions.
