anstromontane saxifrage, Leptasea austromontana, and the 

 glandular phacelia, PhaccUa glandulosa. There is also a brief 

 campestrian vegetation about Eldora, reproducing, in other 

 species, the facies of the Great Plains, Campestres; 

 I may instance as species : Grindelia snhalpina, G. Eldorae, 

 Chrysothauinus Parryi, and C. elegans. 



f. Amnicolae. The montane stream vegetation is seen 

 at its best about small rills. Along the larger streams it as- 

 sumes a typical riparian aspect, much like tb.at of the canon 

 society of the foot-hills along the large streams. Since the 

 water in these streams is very cold inasmuch as they are fed 

 from the wasting snows of the alpine valleys, the montane 

 vegetation can scarcely be distinguished from the true sub- 

 alpine vegetation of the streams. The list of species will, 

 therefore, be deferred until tb.e subalpine stream vegetation 

 is reached. 



E. SUBALPESTRES 



The Subalpine zone extends from about the loooo foot 

 level to timberline, and hence coincides with the upper slopes 

 of the Main Range. It is in the main a forest of Engelmann 

 spruce, with occasional high meadows and bogs. Lakes, too, 

 are numerous. 



I have personal knowledge of only two formations : a. 

 The subalpine forest (Sylvales). b. The subalpine stream 

 (Amnicolae). 



a. Ses. Ival. The subalpine forest consists mainly of 

 Engelmann spruce, Picea Engelmanni, and balsam ^r, Abies 

 lasiocarpa. I have but a very slight knowledge of the herbs 

 characterizing this formation, but I noticed along the Arapahoe 

 Trail the following species, which I had not seen in the mon-
