PREFACE 



The object of this paper is simply to publish at this time the main results 

 of the work done by Marcus E. Jones in connection with the Biological Sta- 

 tion at Bigfork, so far as important notes, changes of names due to exhaus- 

 tive field work and new species are concerned. The ecological work and 

 detailed statement of species and localities, zonal distribution, etc., are 

 reserved for a subsequent paper. In addition such additions to the Flathead 

 drainage flora as have been made by Prof. Elrod, Miss Norton and others 

 are here given for the first time, and credited to them. The total flora 

 passed in review covers some 1700 species. The flora of the Flathead Lake 

 region has now been thoroughly worked up except the early spring flora 

 which is meager. It has been the Mecca of botanists for over a decade, but 

 the only publications on its flora have been a paper on the trees, and one 

 on the lichens and mosses and fungi, all of them very incomplete, and spo- 

 radic articles on the ferns and horsetails. The collections of Williams, Mrs. 

 Kennedy, MacDougal, Canby, and others from this region have been reported 

 in Rydberg's list of the flora of Montana. This present list does not include 

 any commentary on the identifications of Rydberg except on a few important 

 species of rare occurrence. 



Detailed studies of the trees were made and the results are given in 

 this paper. 



The fungi on living leaves were carefully studied and collected. 



A. careful collection of the mosses was also made and nearly a hundred 

 and thirty-five species were added to the known flora. 



In 1908 the main work was around Flathead Lake and the adjacent moun- 

 tains. In 1909 the main work was in the Bitter Root, on McDonald Peak, at 

 Ravalli, the Flathead Plains, Swan River, and the magnificent Sperry Glacier 

 region where the alpine flora reaches its greatest development. Work was 

 also done at Monida and Lima in both years and along the Oregon Short 

 Line, Northern Pacific and Great Northern railways at way stations.
