HERBARIUM 
The herbarium has made a remarkably well-balanced growth 
during the year, having acquired about the usual number of 
plants from various parts of North America, Mexico, Central 
America, and the West Indies, and notably a relatively large 
number of exotic plants, substantially augmenting the rep- 
resentation of the flora of South America, Eastern Asia, the 
Philippine Islands, Formosa, the Himalayas, the Gangetic 
Plains, Finland, ete. The growth of the herbarium, however, 
is not only one of geographical significance, since the collec- 
tions obtained represent essentially all groups of plants. 
New Accessions.—The total number of herbarium speci- 
mens received in 1921 is considerably in excess of the year 
immediately preceding, notwithstanding the fact that no 
large private herbarium was purchased during the year. 
Among the more noteworthy collections acquired since the last 
annual report are the following: from the Arnold Arboretum, 
362 plants of eastern Asia, mainly Korea and Formosa, col- 
lected by E. H. Wilson; Elam Bartholomew, 200 ‘‘North 
American Uredinales’’; Professors G. R. Bisby and A. H. R. 
Buller, 83 specimens of fungi from Manitoba, Canada; Bureau 
of Science, Manila, 892 fungi and mosses of the Philippine 
Islands; Dr. R. P. Burke, 97 specimens of fungi from Ala- 
bama; B. F. Bush, 237 plants of Missouri and South Caro- 
lina; Carnegie Museum, Pittsburgh, 200 plants of Pennsyl- 
vania; Ira W. Clokey, 258 plants of Colorado; Rev. John 
Davis, 1,014 plants of Missouri, North Carolina, and South
