The Botanical Branch. 

 The work of the Botanical Branch during the past year has 

 been confined mainly to the papers and discussions in connection 

 with the meetings of the Branch which have been held during 

 the winter. Little field work in botany was done about Ottawa 

 during the past season. Few young men in Ottawa are interested 

 in systematic botany, and the older men seem to be too busy at 

 their official duties to take time to study plants in the field. 

 Prof. John Macoun spent the summer of 1910 in botanizing in 

 Nova Scotia and added a number of new species to the flora of 

 that province. Mr. James M. Macoun made very valuable 

 collections about Hudson Bay. Mr. H. T. Gussow is doing very 

 important work in investigating plant diseases, especiallv those 

 relating to economic plants. Mr. H. Groh devoted considerable 

 time during the summer of 1910 in studying the native Amelan- 

 chiers and also in noting the species of plants growing or establish- 

 ing themselves in an evergreen plantation at the Central Experi- 

 mental Farm.
