Bulletin No. 28 of the Wyoming Experiment Station 

 contains the " First Report on the Flora of Wyoming," by 

 Aven Nelson, Professor of Botany in the University of 

 Wyoming. This embodies the results of a study of the col- 

 lections made by the author in the years 1894 and 1895, and 

 is largely devoted to a list of the plants known to occur 

 within the boundaries of the state. Three new species and 

 nine new varieties are described. The new species are 

 Aquilegia Laramiensis, Potentilla pinnaiisecia and 

 Hymenopapims ligulaeflorus. The list of species is pre- 

 faced by several pages of comments on the various " floras," 

 the "plant- zones" and similar topics. The list of trees 

 includes twenty-eight species, some of which, however, are 

 hardly more than shrubs. The author thinks that the power 

 of the mountain - plants to withstand freezing is due to the 

 reduced atmospheric pressure at great elevations. Various 

 species were noted in bloom witli the temperature at 5° to 

 20° F. 



The position of Instractor in Botany at the University of 

 Missouri has been awarded to Mr. Charles Henry Thompson, 

 a student under Prof. Trelease at the Missouri Botanical

 near Bakersfield. He is the author of a paper on the 

 " Ligulate Wolffias of the United States " in the Seventh 

 Annual Report of the Missouri Botanical Garden. He is the 

 first to have discovered the rare Wolffia lingulata in Cali- 

 fornia.
