NOTES ON UREDINEAE. !. 
E. \V. D. HOLWAY. 
Puccinia Columbiensis. — In July 1891, J. Macoun col¬ 
lected at Banff, Canada, a rust which he sent to J. B. Ellis as on 
Oenothera biennis. This was distributed to correspondents as 
Puccinia tuberculans E, & E., but published as Puccinia colum¬ 
biensis E. & E. I collected at Banff in 1901, and found a Puccinia 
on Troximon glaucum which proved to be Macoun’s plant, and a 
comparison of the specimens sent me by Mr. Ellis showed that his 
host plant was also' Troximon. To be certain that the type was 
the same thing I asked Prof. Underwood to look it up. There 
are two specimens in the Ellis Herbarium. “Puccinia columbiensis 
E. & E., I, on Oenothera biennis, Cypress Hills, Assinaboine, 
J. Macoun,” and “Puccinia columbiensis E. & E., Ill, on Oeno¬ 
thera biennis, Banff, J. Macoun.” Mr. Rydberg kindly examined 
the hosts and considers the first Solidago mollis, and the second 
Troximon glaucum, or Troximon parviflorum. 
Puccinia Suffusca. — In the “Catalogue des plantes que 
la societe botanique de Copenhague peut distribuer au printemps 
1881,” a rust was offered under the name of Puccinia Pulsatillae 
Rostr., but without desription. Specimens have since been is¬ 
sued under this name in Sydow, Uredineen, No. 1529, and in 
Yestergren, Micromycetes rariores selecti, No. 316, both collected 
in Bohemia on Pulsatilla pratensis. Vestergren, in Bot. Notiser, 
1902:269, quotes from a letter written by the collector, Fr. 
Bubak, as follows: “Durch grossere grobwarzigere Sporen, 
deren Zellen nicht kuglig, sondern elliptisch bis langlich sind 
(besonders die Bazalzelle), ebenso durch spatere Entwicklungs- 
zeit von Puccinia fusca (Relh.) Wint. verschieden.” 
This seems to be a good species, but the name has been used 
by Kalchbrenner, 1865, Math. s. termiszett. Ivozlemenyek 3:307, 
for a different Puccinia. This necessitates a new name for the 
plant and Puccinia suffusca is offered for it. Puccinia fusca seems 
to occur in the United States on Anemone nemorosa only. I have 
examined P. suffusca on Pulsatilla hirsutissima, Decorah, la. Hol- 
way; Ute Pass, Col. Trelease; Helena, Mont., Kelsey. On Ane¬ 
mone parviflora, Col. Crandall; Anemone multifida, Helena, 
Mont., Kelsey. In addition to the characters noted by Bubak, the 
species has numerous one-celled spores, which are quite variable 
in form and size, and the spores are also darker in color. In all 
the specimens examined there is a very distinct difference in the 
markings of the epispore. Under a high power the tubercles of 
P. fusca appear like dots, quite uniform in size and evenly dis¬ 
tributed over the surface. Those of P. suffusca are longer, 
irregular, and often united. 
In this connection it may be of interest to republish Mr.
