NOTES ON WESTERN UREDINEJE. 
BY S. M. TRACY AND B. T. GALLOWAY. 
Cjeoma ribes-alpini, Wint. ( Uredo Jonesii, Pk., Torrey Bulletin, 
XII, p. 3G.) This species occurs in abundance on Ribesaurcum in several 
of the western states and territories, but has not been observed by the 
writers east of Colorado. On comparing our material with authentic 
specimens of Uredo Jonesii , Pk., we find that they agree perfectly; and a- 
further comparison of these forms with European specimens of Coeoma 
ribes-alpini reveals the fact that the so called Uredo Jonesii does not differ 
from the species last named. Von Thumen has distributed this species 
(Mycotheca Universalis , No. 1830) under the name Coeoma ribesii , Lk., but 
Winter (Rab. Krypt. Flora, p. 258) adopts the specific name given it by 
lfersoon. It is probable that Uredo rubicola , C. & E. (Grev. YI, p. 86) is 
the same as Coeoma ribes-alpini, but as we have no specimens of the 
former we cannot assert positively that such is the case.(*) Uredo Jonesii 
was published in 1885, and Uredo rubicola in 1882, Winter’s name thus 
having priority and being the one which should be adopted. Winters 
description agrees very closely with our specimens on Rifles aureum. 
Puccinia flosculosorum, Wint. ( Puccinia balsamorrhiza , Pk., 
Ellis, N. A. F., No. 1833; Trichobasis balsamorrhiza , Pk., Pot. Gaz., YI, 
p. 276.)—There does not seem to be any good reason for separating the 
form on Balsamorrhiza from P. flosculosorum , and we believe that Winter 
considers the two forms identical. The teleutospores were found in 
abundance during August on the leaves of Balsamorrhiza sagittata , near 
Ogden and at other points in Utah. In our specimens the teleutosori 
are quite large and conspicuous and occur on both sides of the leaf. The 
spores are broadly elliptical, punctiform, 18—25 x 30—45 p ; pedicels 
hyaline, very fragile. 
Melampsora lini, Wint.—Rab. Krypt. Flora, p. 246. The uredo 
stage of this species was taken at Flagstaff, Arizona, on Linum perenne , 
and on July 29th was found in great abundance on some host at Elko, 
* Since writing the foregoing we have learned from Mr. Ellis that Uredo rubicola, 
C. & E., does not differ from llredo Jonesii, Pk.—T. & G.
