J. M. CoULTER issued in 1873, under government auspices, a Catalogue of 
Plants collected in 1872 in Portions of Montana, Idaho, Wyoming and Utah. 
The state floras have not been neglected. One of the first for the 
mountain region is entitled Enumeration of the Species of Plants collected by 
Dr. C.C. ParrY and Messrs. E. Harı and J. P. HARBOUR during the Summer 
and Autumn of 1862 on and near the Rocky mountains in Colorado Terr. by 
Asa GRAY published in the Proceedings of the Academy of Natural Sciences 
of Philadelphia in 1863. 
The Synopsis of the Flora of Colorado by T. C. PoRTER and J. M. 
COULTER, printed as a government publication in 1874, is often referred to 
in the earlier works on the botany of the western United States. It, and the 
Flora of Southwestern Colorado by T. S. BRANDEGEE (1876) are the most im- 
portant of the early papers dealing with the botany of the State. Asa GRAY 
and J. D. HoOKER later in 1881 printed a paper in which they compared the 
vegetation of the Rocky Mountain Region with other parts of the world mention- 
ing the more salient features of the mountain flora. — Two papers dealing 
with the phytogeography of the Rocky mountains are in line with the paper 
of Gray and Hooker. Reference is made to an article by T. D. A. COCKERELL 
in Science (May 6th, 1898) on the Diverse Floras of the Rocky Mountain 
Region and to another by P. A. RYDBERG entitled Composition of the Rocky 
mountain Flora also published in Science (1900). 
The Yellowstone Region is now well represented by floras and papers 
on its botanic aspects. One of the first published by the government in 1882 
is a List of Plants collected on Lieut. General P. H. SHERIDAN’s Expedition 
through the Big Horn Mountains, Yellowstone National Park, etc. in 1881 by 
Surgeon W. H. Forwoop. TWEEDY’s Flora of the Yellowstone National Park 
was printed in pamphlet form in 1886. The vegetation of the hot springs has 
also received a considerable share of attention and articles by WEED, BAY, 
HARSHBERGER, DAVIS, SETCHELL and TILDEN have appeared on the subject. 
The most voluminous work, however, is RYDBERG’s Catalogue of the Flora 
- of Montana and the Yellowstone Park issued as the first volume of 
Memoirs of the New York Botanical Garden in 1900. In this work, the author 
gives an account of the herbaria consulted, the botanists engaged in field work 
and the localities visited. Besides these papers on the Flora of Idaho, Coeur 
d’Alene mountains, Big Horn mountains, Black Hills of Dakota, Bitterroot 
mountains, Teton mountains have been published as Contributions from the 
United States National Herbarium and as reports in the United States Geological 
Survey, Annual Reports ıgth, zoth and 2ıst. AYEN NELSON has contributed 
notes and has written a Flora of Wyoming. The only general work for BR 
region is the Manual of the Botany of the Rocky Mountain Region Ta 
New Mexico to the British Boundary by JOHN M. COULTER. The first edition, 
which only claims to be a compilation, an orderly arrangement of rn 
material, was published in 1885. This work is in need of revision and 5 . 
RYDBERG is at work upon a manual which will fill the long. felt want ol an
