FurtHer Notes on Tirmotuy Ruwvst. 
By A. G. JOHNSON. 
At the last two annual meetings of the Academy, papers on timothy 
rust, [Puccinia poculiformis (Jacq.) Wettst.], were presented by Mr. 
Frank D. Kern, and it is of interest to note at this time the present known 
distribution of the disease over the State as well as to record here the 
extension of its range into other States and provinces from which it has 
net been previously reported. 
As was predicted in Mr. Kern’s papers, the distribution of the rust 
has become more general. In this State it evidently occurs wherever timo- 
thy is raised. During the past season the writer has collected it at widely 
separated points, as follows: Mount Vernon (Posey Co.) on the south- 
west; Wirt (Jefferson Co.) to the southeast; Richmond (Wayne Co.), 
east central; Columbia City (Whitley Co.), Laketon (Wabash Co.), and 
Logansport (Cass Co.), nerth central; LaFayette (Tippecanoe Co.), west 
central. Besides these collections, specimens of the rust have been re- 
ceived from Mr. Guy West Wilson and Mr. C. D. Learn, both collections 
from Carmel (Hamilton Co.), central; and it was reported last year from 
Columbus (Bartholomew Co.). This covers the State in such a way as to 
lead one to be reasonably certain that the rust occurs throughout the 
State wherever its host does. 
In addition to the states and provinces from which the rust has been 
previously reported, specimens have been received from Dr. E. W. Olive, 
collected at Brookings, S. Dak., who reports it as commen there this year, 
although not previously seen; from Miss Irma A. Uhde, collected at Lake 
Okoboji, Iowa; and from Prof. W. P. Fraser, Pictou, Nova Scotia. These 
localities in addition to those noted in Mr. Kern’s paper last year make 
the known distribution of this rust in North America as follows. S. Da- 
kota, Minnesota, Iowa, Wisconsin, Indiana, Ontario, New York, Maine and 
Nova Scotia. 
In most of the specimens seen, especially those from Indiana, the sum- 
mer spores (urediniospores) were much the more abundant. Winter 
spores (teliospores) developed in some cases but not abundantly. In certain
