Plants. — Among the accessions of the year Avere several of excep- 

 tional value, the more noteworthy being as follows: Over 10,000 

 specimens were received from the Bureau of Plant Inclustr}^ and 

 tlie Biological Survey, of the Department of Agriculture, compris- 

 ing, besides 1,500 miscellaneous plants, more than 1,200 mounted 

 grasses, collected by Prof. A. S. Hitchcock during an investigation 

 of this group in Nevada, California, Utah, and Arizona, and also 

 6,000 duplicate grasses, consisting of 30 sets of 200 specimens each 

 of certain species which have been critically studied by Prof. Hitch- 

 cock and Mrs. xVgnes Chase in recent years, and of wdiich it has been 

 considered desirable to distribute authentic specimens. The Xew 

 York Botanical Garden furnished 3,555 plants in exchange, of which 

 562 were African specimens from the Otto Kuntze Herbarium, and 

 the remainder entirely from the "West Indies, supplementing very 

 acceptably the large series acquired from the same source in recent 

 3'ears, and resulting from investigations by that institution. Some 

 1,580 Chinese plants, representing a second installment of one of the 

 largest sets of the exceedingly valuable collections made by Mr. E. H. 

 "Wilson, were purchased of Prof. C. S. Sargent. 



A notable collection of cryptogams, numbering about 10,000 speci- 

 mens, largely obtained by the late Mr. John B. Leiberg while engaged 

 in field work in the western United States, was received as a gift from 

 Mrs. Leiberg, of Leaburg, Oreg. It contains many duplicates which 

 will be available for distribution as soon as the species have been fully 

 identified. An important addition from a region not well represented 

 in the herbarium consisted of 1,100 plants from "Venezuela, of which 

 300, chiefly from the high mountains of that country, were purchased 

 of Mr. Alfredo Jahn, Caracas, while the remainder, presented by 

 Mr. H. Pittier, were secured by him in the course of an investigation 

 of the agricultural resources of Venezuela. From the Bureau of 

 Science at Manila 1,T16 specimens were obtained in exchange, nearly 

 1,000 of these having come from Guam, and being duplicates of mate- 

 rial which had served as the basis of an extensive rejDort on the flora
