List of plants collected above timber line on Pikes Peak, with altitu- 
dinal extensions and notes 
BLANCHE SOTH 
Experts might be able to differentiate a few other varieties 
and species of grasses and sedges in addition to the conspicuous 
ones given in the following list of plants collected above the timber 
line on Pikes Peak; otherwise this list is exhaustive and my 
determinations have been corrected and _ verified by the sub- 
mission of doubtful specimens to Dr. P. A. Rydberg and Dr. 
Aven Nelson, both of whom have been most kind in this respect 
as well as in giving me information upon doubtful points. They 
have my sincere thanks for their interest and assistance.
