Notes upon the northwestern and Rocky mountain flora. I.—In the 
summer of 1892 I made a very interesting trip in the northwest. The 
months of June, July and August were spent in Idaho. My work in 
that state was done in the sage brush of the southern part, in the 
Owyhee mountains to the southwest, and in the highlands, foothills 
and mountains of the central and eastern portions. I traveled by rail- 
road to the principal points, and by stage, carriage or horseback to 
more distant ones. Of course I walked a good deal. I was well pro- 
vided with letters of introduction, and there was seldom any difficulty 
i procuring company whenever desirable, which was necessarily a 
Steat part of the time. During the entire season a collection of about 
eleven hundred species was made, two-thirds of which were from 
Idaho. Many of these are interesting from the fact that they show 
hew and unexpected localities, and many for showing variations de- 
veloped under changed conditions. Some plants seem to be quite 
new. I have learned to regard Idaho asa meeting place of various 
floras. There one meets with sub-arctic plants from the north which 
can even be traced to Siberia, and the Cacti and other southern plants 
. aga There is a large desert flora and also moist thickets and 
la a 4 most luxuriant vegetation. The Rocky mountain 
ees a those of California. In general, should say that its veg- 
"eats ela nearly allied to that of the Pacific slope. 
Sia oo my appreciation of the kindness and encourage- 
ion ; $ both from my friends east of the Rockies, and from 
their ‘icy Ortunate as to make in the state. Had it not been for 
ein Coral ina I could not have reached many of the distant 
a eae regions which I visited.
