No. 1064. PUCCINIA OMNIVORA E. & E. is a synonym 
of P. Windsoriae Schw. The host was erroneously determined 
it being in reality Tricu&pis sesleriodes. 
No. 1071. PUCCINIA PROCERA D. & H. is founded on 
the same species of host, Elynus condensatus, as P. montanensis 
Ellis. The former was published in December, 1893, and is clearly 
a synonym of the latter, which was published in May, 1893. It 
is probable that neither of these names covers the rust on Elymus 
Canadensis and similar hosts occurring east of the Rocky moun¬ 
tains. Culture experiments have shown that the form on Elymus 
Virginicus has its aecidium on Imp aliens, and possibly that on 
E. striatus, but not the form on E. Canadensis, whose affinities are 
not at present known. 
No. 1086. PUCCINIA MELICAE (Erikss.) Syd. occurs 
in abundance in the vicinity of Lafayette, Ind., on Melica diffusa 
Pursh. As in Europe, the uredospores are formed in the greatest 
abundance, but the teleutospores only appear very late in the 
season. 
No. 1087. PUCCINIA MILII Erikss. has been recently 
reported by Dr. J. J. Davis from Wisconsin. It was found in the 
uredoform in Vilas Co., Wis., July 11, 1901, on Oryzopsis asperi- 
folia Minchx., but it was not until teleutospores were obtained, 
Sept. 30, 1903, that the determination of the species could be made. 
It was also gathered by the same collector at Racine, Wis., Aug. 
8, 1903, on Melium effusum L., showing only the uredo. The 
American material agrees perfectly with the European, especially 
with Eriksson’s No. 450 in his Fungi parasitica scandinavici. 
No. 1101. PUCCINIA ESCLAVENSIS D. & H. should 
be written P. eslavensis, there being a clerical error in the original 
publication. The name is derived from Eslava (not Esclava), 
the place where the type collection was made. 
No. 1147. PUCCINIA STIPAE Arth. is entirely distinct 
from the European form on Stipa, as cultures not yet published 
have abundantly demonstrated. The names used by Opiz and 
ITora do not, therefore, apply to the American species, and indeed, 
are not applicable to the European species, because they are both 
nomina nuda. 
No. 1150. PUCCINIA SUBSTERILIS E. & E. is a syn¬ 
onym of P. Stipae Arth., for the so-called uredospores are the 
resting form, or amphispores, of that species. 
No. 1157. PUCCINIA AGROPYRI E. & E. Aecidia of 
this species are known to occur in North America upon Clematis 
ligusticifolia in Colorado, Montana, Wyoming and Nebraska, on 
C. Scottii in Colorado, on C. lasiantha in California, on Fremontii 
in Kansas, on C. Drummondii in Arizona, and on C. Viorna in 
Iowa. The forms on C. Virginiana and C. Douglasii do not be-
