The Uredinales of Indiana. 



By H. S. Jackson. 



The first authentic record of the collection of any species of plant rust 

 in Indiana of which we have any knowledge was made by Dr. J. M. Coulter 

 in the Botanical Bulletin (Botanical Gazette) 1:20, 1876. In a short article 

 he noted the common occurrence of ■ Uromyces lespedezae Schw. on Lespedeza 

 violacea, presumably in the vicinity of Hanover. 



The first account of the rusts of the State presented before the Indiana 

 Academy of Science was included in a paper by E. M. Fisher on the Parasitic 

 Fungi of Indiana, which was read at the annual meeting for 1890. This 

 paper listed a considerable number of species of Uredineae, but unfortunately 

 was not published and is unavailable. The specimens on which the paper 

 was based were deposited in the-herbarium of the United States Depart- 

 ment of Agriculture. A list of the species was, however, obtained by Dr. 

 L. M. Underwood and included in his "List of the Cryptogams at present 

 known to inhabit the State of Indiana," which was printed in the Proceedings 

 for 1893. 



The latter list forms the basis of our knowledge of the cryptogamic flora 

 of the State and enumerates 88 species of Uredinales including the unattached 

 aecial and uredinial forms. Supplementary lists by various authors have 

 appeared in the Proceedings from time to time since that date, only the most 

 noteworthy of which need be mentioned. 



In 1896 Miss Lillian Snyder presented a list of the rusts of Tippecanoe 

 county, supplementing the work in 1898 with lists from Madison and Noble 

 counties. The rusts of Hamilton and Marion counties were listed by Gr. W. 

 Wilson in 1905. 



Two complete State lists have been presented to the Academy by Dr. 

 J. C. Arthur. The first was read in 1898 and enumerated 80 species; the 

 second was presented in 1903 and included 105 species. Both these lists were 

 prepared in such form as to illustrate the latest developments in revised 

 nomenclature. The unattached aecial and uredinial forms were omitted. 



The present list is based on the information contained in all the preceding 

 ones which have appeared in the Proceedings of the Academy, together with 

 the wealth of material collected in all parts of the State contained in the
