48 Wyoming Experiment Station. 



Although what has been done in the study of the 

 flora of the state has cost no little time and labor yet the 

 work seems but barely begun. The preparation of a full 

 and reasonably inclusive report on the flora of a great 

 state of nearly 100,000 square miles would be the work of 

 years for a corps of men devoting their full time to the 

 matter in hand, so one man with a full slate of college 

 teaching and other Experiment Station duties, besides 

 that of working up the flora, would lose courage were it 

 not for the absorbing interest of the subject itself. Since 

 to delay the report until it should be approximately com- 

 plete would project it far into the future and might pos- 

 sibly result in its never being published, it has seemed 

 advisable to publish the results thus far attained. As the 

 work goes on and results accumulate, other reports may, 

 from time to time, appear to record the additions. 



COLLECTING TRIPS. 



The basis for the following brief report and the cata- 

 logue of species rests mainly upon the collections made 

 by the writer in 1894 and in 1S95. 



With one exception, as given below, no systematic 

 work in collecting had previously been done. In 1892, 

 Prof. B. C. Buffum, at that time acting botanist of the 

 Station, spent the mid-summer months in the field collect- 

 ing — primarily to secure for the University and the Sta- 

 tion a collection of the native grasses and forage plants, an 

 exhibit of which was to be made at the World's Fair at 

 Chicago in 1893. Incidently much more was done, for a 

 considerable amount of good material, other than grasses, 

 must be put down to the credit of the expedition. 



From this material were obtained the numbers which 

 formed the nucleus of the present collection in our her-
