252 CONTRIBUTIOISrS FROM THE NATIONAL HERBARIUM. 



In 1900 Dr. David Griffiths, of the United States Department of 

 Agriculture, in company with Mr. E. F, Lange, visited western Mon- 

 tana for the purpose of studying the grasses. He spent about a week 

 at Summit, a station on the Great Northern Railroad, on the south 

 boundary of the park. He collected grasses here and at other stations 

 in the vicinity. 



In 1901 Dr. Stuart Weller, of the University of Chicago, was 

 paleontologist of a party sent out by the United States Geological 

 Survey to determine the condition of the international boundary 

 monuments, and to secure information regarding the geology of the 

 region traversed. Doctor Weller obtained a small collection of 

 plants, some of which are not otherwise known from the region. All 

 those seen by the writer are from the northern portion of the east 

 slope. 



In the same year Mr. F. K. Vreeland, an electrical engineer of New 

 York City, made a rather extensive collection on the west slope, in the 

 region of McDonald and Camas lakes. The plants were determined 

 at the New York Botanical Garden by Dr. P. A. Rydberg, and a partial 

 set of them is in the National Herbarium. Several species were 

 described as new by Doctor Rydberg from this collection. 



In 1914 Prof. A. S. Hitchcock, of the Department of Agriculture, 

 spent three weeks in Glacier Park, collecting grasses. The list of 

 grasses presented here is based chiefly upon lus collections. In addi- 

 tion he obtained a considerable series of other plants, 



Mr. Vernon Bailey, of the Bureau of Biological Survey, Department 

 of Agriculture, made a small collection of plants in the park in 1917, 

 while engaged in the preparation of his report upon tlie mammals. 



Mrs. Otto Thompson, of Glacier Park station, has presented to 

 the National Museum two small collections of the early spring plants, 

 from the vicinity of the east entrance. These contain some species 

 not otherwise known from the region. 



The collections enumerated above are the only ones in the National 

 Herbarium from Glacier Park, but several others have been made in 

 the region. Mr. Marcus E. Jones, of Salt Lake City, Utah, collected 

 in the park, chiefly at Sperry Glacier, and he has published a list of the 

 species obtained (see bibliography). Mr. John G. Jack, of the Arnold 

 Arboretum, made a collection of trees and shrubs at St. Mary Lake in 

 September, 1918. Others who have collected in the park are Miss 

 Gertrude P. Norton; Prof. M. J. Elrod, of the University of Montana; 

 Mr. M. P. Somes, of Kalispell, Montana; and Mr. Titus Ulke, 



There should not be omitted, also, the tourists, some of them 

 amateur botanists of no mean ability, who every year preserve dried 

 specimens of the plants whose acquaintance they make here for 

 the first time. There must be dozens, if not hundreds, of such herba-
