(Uredo polypodii (P.) Preliminary List.) On Cys- 
topteris bulbifera Bernli. Wisconsin fide North 
American Flora 7, 2, 113. 
219. Puccinia pustulata (M. A. Curtis.) Arth. 
Dr. Arthur has shown by cultures that Aecidium 
pustulatum M. A. Curtis is the aecial stage of a 
rust to which he gives the above name and which 
develops its further stages on Andropogon. As 
this Aecidium is abundant about Eacine while I 
have not seen the one on Pentstemon I infer that 
the uredinia and telia that I have collected in 
this vicinity on Andropogon furcatus Muhl. and 
A. scoparius Michx. belong to this species. 
229. Puccinia impatientis (Schw.) Arth. 
Uredinia and telia on Elymus Virginicus L. re¬ 
ferred to Puccinia rubigo vera (DC.) Wint. in 
the supplementary list is to be placed here, Dr. 
Arthur having shown that it is genetically con¬ 
nected with Aecidium impatientis Schw. 
245. Gymnosporangium davisii Kern. 
Telia on Juniperus communis L. var. depressa Pursh. 
Wind Lake. In the Preliminary List under this 
number spermogonia collected at La Crosse on 
Pyrus arbutifolia L. by Pammel were doubt¬ 
fully referred to Poestelia transformans Ell. I 
have collected the pycnia on Pyrus melanocarpa 
(Michx.) WiTd. at Sullivan and Waupaca as 
well as at Wind Lake. The aecia are of slow 
growth and seem not to have been collected in 
Wisconsin as yet. The demonstration of the con¬ 
nection of the stages on the juniper and the 
choke berry was made by Mr. F. D. Kern of 
Purdue university using Wisconsin material for 
inoculation.
