REPORT ON THE CRYPTOGAMIC HERBARIUM 



Dr. C. Stuart Gager, Director. 



Sir: I beg to submit herewith the Annual Report on the Crypto- 

 gamic Herbarium for the year 1922. 



The following table (p. 81) shows the number of specimens re- 

 ceived, their source, and other pertinent information: 



Mrs. Annie Morrill Smith presented to the Garden valuable lists, 

 letters, etc., pertaining to mosses and hepatics collected at Chilson 

 Lake, Essex Co., New York, a set of which is in the Cryptogamic 

 Herbarium, presented to the Garden by Mrs. Smith several years 

 ago. 



Special note may be made of the collection of Rusts and Smuts 

 received in exchange from the Office of Pathological Collections 

 of the U. S. Department of Agriculture. The Garden has received 

 practically a complete set of the specimens prepared for exchange 

 by that office. 



By far the most important single addition ever made to the 

 Cryptogamic Herbarium is the excellent mycological collection of 

 Dr. Franz Bubak, formerly Director of the Botanical Garden at 

 Tabor, Czecho-Slovakia. The collection includes a total of 33,779
