238 REPORT OF NATIONAL MUSEUM, 1890 



ACCESSIONS. 



The accessions to the Herbarium are received in part through the 

 National Museum, but mostly through the Department of Agriculture. 

 The total number for the year is 370. Of these, 24 came through the 

 National Museum. Following are some of the more important accessions: 



A set of 550 species of Japanese plants from S. Tegima, Director of the Educational 

 Museum, Tokio, Japan. 



A set of 335 species collected in Mexico by C. G. Pringle. 



About 1,800 specimens of south Californian plants, many of them duplicates, from 

 C. R. Orcutt, San Diego, California. 



A set of 80 species of Canadian grasses from John Macoun. Geological and Natural 

 History Survey of Cauada. 



Texan plants (2,817 specimens) collected by G. C. Nealley, of Houston, Texas. 



A collection of about 900 specimens of east Floridan plants from J. H. Simpson, 

 Manatee, Florida. 



A collection of about 4,000 specimens made by Edward Palmer in Lower California 

 and western Mexico. 



Californian and Mexican plants from the California Academy of Science (327 spec- 

 imens). 



The first 135 species of a set of Bolivian plants collected by Miguel Bang. 



About 100 Pacific slope species, many of them new, from E. L. Greene, Berkeley, 

 California. 



A set of 142 species of the Hepaticse Cubenses WrightianaB from the Harvard Uni- 

 versity Herbarium. 



About 500 specimens from the U. S. Eclipse Expedition to Africa. 



European mosses from Dr. I. Hagen, Troudhjem, Norway (320 species). 



About 800 specimens collected by Frederick V. Coville in Virginia and North Car- 

 olina. 



Many of the accessions were single specimens, or a few specimens 

 sent for identification merely, and not prepared for the Herbarium. 

 While the number of such accessions is considerable, the proportion of 

 the specimens contained in them to all those received is small. The 

 total number of specimens received in accession is 21,346.* 



HERBARIUM AT THE DEPARTMENT OF AGRICULTURE. 



The Herbarium specimens received are disposed in two places, the 

 herbarium proper and the duplicate herbarium. The latter is used as 

 an exchange stock, which is very valuable in transactions with foreign 

 botauists. 



The force employed in mounting and labeling specimens is .able to 

 perform the amount of work at present required, while the number 

 engaged in identifying plants has been increased during the last few 

 months, so that there appears to be no immediate pressing need for 

 additional assistants. 



The number of specimens mounted is estimated to be about 125,000; 

 in the duplicate herbarium, about 15,000; and of those not yet ex- 

 amined, about 10,000. About 0,000 specimens have been mounted 

 during the year. 



Single packages or single accessions wore in some cases estimated, not counted.
