evidently the same form as referred to by Tracy and Galloway, 8 
and T. D. A. Cockerell. 3 4 It is characterized by its elongated cup; 
but according to Dr. Arthur it is not thought to be specifically 
distinct from the above. Both of the above citations refer it 
doubtfully to the Aecidium stage of P. mirabilissima Pk. No 
cultures * have been made to lead to this belief, and we do not 
know of the two having been observed in the same locality. 
Puccinia saxifrage Schlecht.— On Mitella pentandra. 
No. 1202, Merrill and Wilcox, Snake River, 20 miles south of 
Jackson, Wyo., July 19. 
Puccinia setarue Diet. & Holw.— This species was de¬ 
scribed 5 6 and issued by Arthur and Holway in their Uredinese 
Exsiccatae as occurring on Sectaria imberbis (Poir.) R. & S. At 
the time the host was determined by Prof. Scribner the species 
of Setaria (now Chaetochloa) were imperfectly known. Later in 
revising the genus, 0 Scribner and Merrill changed the determina¬ 
tion of the specimen sent by Mr. Holway, which is now in the 
herbarium of the office of the Agrostologist, to Chaetochloa pur- 
purascens (H. B. K.) S. & M. The species also occurs on No. 
3556, J. N. Rose, City of Mexico, Mex. October 3, 1899. 
Puccinia thalictri Chev.— On Thalictrum fendleri. No. 
1215, Merrill and Wilcox, Leigh’s Lake, Wyo., July 26. 
Puccinia tosta Arth.— Under the description of this 
species 7 was cited two collections on Sporobolus utilis. The au¬ 
thor has the specimen that was sent by Mr. Cockerell to the office 
of the Agrostologist for identification of the host, and it was 
determined at that time as Sporobolus depauperatus. The au¬ 
thor has again compared the specimen with typical material in 
the herbarium of the office of the Agrostologist and confirms the 
original determination. The two species are easily confused from 
a small specimen or without roots, but their habit is quite differ¬ 
ent. It is probable that the specimens collected by Griffiths are 
also on the same host. 
Puccinia variolans Hark.— On Eriocarpum spinulosum. 
No. 1221, Merrill and Wilcox, Laramie River, 16 miles S. W. 
of Laramie, Wyo., August 22. 
Rcestelia sp. indet.—On Amelanchier pumila. No. 1204, 
Merrill and Wilcox, Snake River, Menoe’s Ferry, Wyo., July 23. 
In habit this resembles R. harknessi, but Dr. Thaxter thinks that 
it is neither of our eastern ones. It may prove to be new.
