4. Aecidium monoicum Peck. 
On Arabis retrofracta Graham: 2131 , July 7, 1911, Gold Basin, 
La Sal Mts., San Juan Co. Dr. Arthur has proved by cultures 2 
that the form of Aecidium monoicum on the Arabis hosts is con- 
nected with Puccinia triseti Erik, on Trisetum subspicatum ) and 
has united the two under the name of Puccinia monoica (Peck) 
Arthur. In my previous paper, I included an Aecidium on Sophia 
sp. as a form of Aecidium monoicum. This Aecidium differed 
strikingly, however, from the specimens taken on the Arabis hosts. 
The form on Sophia (my number 733) had bright orange peridia 
that are conspicuously long; while on the Arabis hosts they are 
pale yellow and not so long. According to Dr. Arthur, the col- 
lection on Sophia is the aecial stage of Puccinia subnitens Dietel. 
The collection was made however at an altitude of about 2,610 
meters and in a spruce-fir association, neither of which conditions 
point to the probable presence of Distichlis.
