ARTHUR: NEW SPECIES OF UREDINEAE 143 
1912, Nelson & Macbride 1794 (type); near Gogorza, Summit 
County, Utah, June 29, 1915, A. O. Garrett 2286. Among autoe- 
cious species this appears to be most like Uromyces Acetosae 
Schrét., a European species on Rumex, but the urediniospores are 
verrucose and not echinulate and have a different number of pores, 
while the teliospores are contrasted in the coarseness and arrange- 
ment of the markings. There appears to be no correlated form 
among the many species of Puccinia on either Polygonum or 
Rumex. The rust covers the leaves heavily with the conspicuous 
sori, inducing a more or less mottled, reddish appearance of the 
tissues. The specimen from Utah was labelled Pentstemon pro- 
cerus, but both host and rust appear identical with the one from 
Idaho. 
Uromyces Krameriae Long, sp. nov. 
III. Telia amphigenous and caulicolous, soon opening by a 
longitudinal slit, chestnut-brown, loosely and prominently pulvi- 
nate, oblong, 0.1-2 mm. long, ruptured epidermis conspicuous; 
teliospores broadly ellipsoid or globoid, 21-23 by 23-294; wall 
cinnamon-brown, 2.5-3 » thick, thicker above, 6-9 », including a 
broad paler umbo, smooth; pedicel hyaline, once to twice or more 
the length of the spore. 
On Krameria glandulosa Rose & Painter, Denton, Texas, 
October 21, 1901, W. H. Long 1to7z. The host has usually 
passed under the name of K. parvifolia, a species of Lower 
California. This rust was received a long time since with 
the name as given above. I do not find that the species has 
yet had the name established, and so take this opportunity to 
place it in use. It is one of the numerous finds made by Mr. 
W. H. Long, while living in northern Texas, and affords one more 
evidence of Mr. Long’s extended and efficient study of the rusts. 
No urediniospores were detected, but the appearance of the rust 
is not that of a short-cycle form; it is more likely to possess cupulate 
aecia. Only the one collection is known. 
Puccinia wyomensis sp. nov. 
O and I. Pycnia and aecia unknown 
II. Uredinia chiefly bet sca tose naied: biline to linear, 
0.6-2 mm. in length, 0.2-0.4 mm. wide, tardily naked, finally 
opening by a longitudinal slit, pulverulent, golden-brown, rup-
