NO. 4 COOPERATIVE WORK OF THE INSTITUTION 1/ 



the publication of the " Flora of the District of Columbia and Vicin- 

 ity," under the editorship of A. S. Hitchcock and Paul C. Standley, 

 dealing with the ferns and flowering plants of this region. Supple- 

 mentary work, including similar treatment of the lower cryptogams, 

 is under way. 



Flora of the National Parks. — At the request of the National 

 Park Service, Department of the Interior, Mr. Standley was detailed 

 in the summer of 1919 to make a botanical survey of Glacier 

 National Park, Montana, the expenses of the work being shared 

 between the National Museum and the Park Service. The very 

 large number of plants and plant photographs obtained have served 

 as the basis of two reports, one a technical paper published as Part 5 

 of volume 22, Contributions from the U. S. National Herbarium, the 

 other a profusely illustrated manuscript of a non-technical nature to 

 be published eventually by the Park Service. 



Flora of the Pacific Coast. — An illustrated Flora of the Pacific 

 Coast (Washington, Oregon, and California), to appear in three or 

 four large volumes, is being prepared under the direction of Prof. 

 LeRoy Abrams, Department of Botany, Leland Stanford University, 

 California. Messrs. William R. Maxon and A. S. Hitchcock have 

 collaborated in this work. 



Cooperation with the U. S. Department of Agriculture. — The rela- 

 tionship existing between the Department of Agriculture and the 

 National Herbarium is naturally a very close one. Not only are 

 thousands of specimens transferred to the National Herbarium by 

 the Department each year, but the herbarium is used constantly by 

 many members of the staff of the Bureau of Plant Industry and 

 Bureau of the Biological Survey, and in many instances, extensive 

 work of identification of material for these bureaus is performed by 

 the staff of the National Herbarium. Until recently nearly all botani- 

 cal material collected through the wide activities of the Bureau of 

 Biological Survey was so determined, and at the present time all 

 specimens collected in the national forests of New Mexico under 

 the auspices of the Forest Service are referred here for identification. 

 In 1912, the grass collection maintained by the Bureau of Plant In- 

 dustry was transferred to the custody of the Smithsonian Institution, 

 office and herbarium space being provided at the National Herbarium, 

 of which the collections thus became an integral part. The staff, 

 consisting of Dr. A. S. Hitchcock and Mrs. Agnes Chase with two 

 assistants, is thus maintained by the Department of Agriculture. 

 A large number of monographic and regional papers on grasses by 

 Doctor Hitchcock and Mrs. Chase have been published in the Contri-
