teleutospores have been described, Mr. Holway has col- 
lected beautiful specimens of this fungus on Clarkia elegans 
in California (Camp Badger) with uredo- and teleutospores 
and has sent me, too, a specimen on Clarkia pulchella with — 
uredospores from Idaho, collected by Mr. Geo. B. Aiton, — 
From these the following description is taken. Sori hypo- 
phyllous, the teleutospore layers often arranged into circles, | 
rather long, covered by the elevated epidermis. Uredospores 
broadly ovate or nearly spherical, brown, echinulate, 22-20% 
18.5-25. Teleutospores oblong, upper cell rounded or ob- 
conical, sometimes with a distinct papilla, thickened at the 
apex in different degrees, lower cell rounded or somewhat 
attenuated below, central constriction little, epispore smooth, 
chestnut brown, 37-50X20-254: Pedicels firm, long.

Judging from the size of the spores and the gener ap
