The additions to the herbarium were very extensive, exceeding 

 27.000 specimens. Two large donations deserve special mention. Dr. 

 Charles ]\Iohr, of Mobile, Ala., an enthusiastic botanist and collector, 

 presented to the Institution his herbarium of more than 3,000 speci- 

 mens, chiefly from the southern United States. As the national her- 

 barium was previously deficient in plants from the South, Dr. Mohr's 

 contribution was especially acceptable. Of similar importance was 

 the donation of the De Chalmot collection of 3,000 plants, from the 

 United States and Europe, by Mrs. Marie De Chalmot, of Holcombs 

 Rock, Va. In the same connection should be mentioned the gift of 

 about 1,100 plants, chiefly from the ITnited States, by Mr. A. H. Cur- 

 tiss, of Jacksonville, Fla. 



Extensive series from Porto Rico, Mexico, the District of Colum- 

 bia, the Yellowstone National Park, the Pribilof Islands, Canada, 

 Jamaica, and the New England States were purchased, and collections 

 from Montana, Central America, and the Philippine Islands were 

 obtained by exchange.
