STANDLEY FLORA OF GLACIER PARK. 253 



ria scattered about the United States, some of which in the course of 

 time will doubtless pass into the possession of the larger botanical 

 institutions. 



ACKNOWLEDGMENTS. 



The field investigation of which this publication is a result was 

 performed under the direction of the National Park Service, and the 

 officials of that ofHce have facilitated the work in every possible man- 

 ner. To Mr. W. W. Payne, superintendent of Glacier Park, and to 

 several of the park rangers, the writer is particularly^ indebted for 

 assistance while in the field. Acknowledgments aie due also to Mr. 

 H. A. Noble, of the Glacier Park Hotel Co. ; to Mr. Roe Emery, of the 

 Glacier Park Transportation Co.; and to Mr. J. E. Lewis, of the 

 Glacier Hotel, all of whom aided materially in the successful prose- 

 cution of the field work. Many of the employees of the hotel and 

 transportation companies also rendered important assistance in many 

 ways. 



The late Miss Gertrude Norton, of Salt Lake City, contributed a 

 large amount of information regarding the plants of Montana, much 

 of which is published here. Through her long field work in Montana 

 Miss Norton had gained an intimate knowledge of the plants, espe- 

 cially the orchids, and she shared this knowledge generously with 

 visitors to the park. 



The writer is deeply indebted to those who have assisted directly 

 in preparing the accompanying account of the Glacier Park flora. 

 Mrs. Agnes Chase, of the United States Department of Agriculture, 

 has prepared the account of the grasses; Mr. C. R. Ball, of the Depart- 

 ment of Agriculture, that of the willows; and Mr. Kenneth K. Mac- 

 kenzie, of New York City, the treatment of the genus Carex. Prof. 

 J. H. Schaffner, of Ohio State University, has furnished the key to 

 the species of Equisetum. 



BIBLIOGRAPHY. 



Very little has been published upon the flora of Glacier Park, and 

 the following list is believed to include practically all the botanical 

 literature relating to the region. Strangely enough, over half of the 

 papers deal partly or exclusively with the lower cryptogams.

 on physiography and life zones, by Vernon Bailey; The biids, by Florence

 showing the distribution of the life zones of the park.
