Accessions— Botany 



The largest gifts to the phanerogamic herbarium consisted of 4,723 

 plants of the United States collected by Holly Reed Bennett of Chi- 

 cago and 183 mounted herbarium specimens of cycads donated by 

 the University of Chicago. The largest collections of plants acquired 

 through exchange were received from the University of Michigan 

 (1,118 phanerogams of Norway and Sweden collected by Louis 

 Jordal and 1,338 vascular plants of Australia collected by M. S. 

 Clemens) and from DePauw University (1,317 vascular plants of 

 Jamaica collected by Professor G. T. Yuncker). A notable collec- 

 tion of 1,475 phanerogams of Costa Rica made by Dr. Carlson, 

 Associate, was purchased from her. The cryptogamic herbarium 

 was given an interesting collection of 79 fungi by Associate Curator 

 Henry S. Dybas, of the Museum's Department of Zoology. 



Care of the Collections— Botany 



During the year 15,478 plants were mounted and added to the 

 phanerogamic herbarium. Mounting and poisoning were done by 

 Mrs. Ann Bigelow, Miss Olive Doig, Mrs. Jennie Pletinckx, and 

 Nils Siegbahn, aided by Robert Yule and, for part of the year, by 

 Miss Mary-Ann Baugh, Miss Elaine Herman, Miss Linda Oatman, 

 and Miss Adrienne Watkins (student assistants) and by Miss Karin 

 Krause, Miss Ruth A. Morris, Miss Patricia Roth, and Miss Alice 

 Schwartz (Antioch College students). Additional aid in plant 

 mounting was furnished in November and December by Group 1 

 of the Girl Scouts of Du Page County (Mrs. E. C. Gollan, Leader, 

 Downers Grove) as their Museum Aid Project. A total of 23,382 

 phanerogams was sent out in exchange. Miss Alice Middleton and 

 Mrs. EfRe M. Schugman mounted 123 specimens of cryptogams for 

 the general collection and repaired and remounted 7,850 specimens. 

 During the year a total of 130 wood specimens was sent out in 

 exchange. Curator Thieret was assisted in the care of the wood, 

 seed, and economic collections for part of the year by Mrs. Bigelow 

 and Miss Watkins. Work on restoration of the type-photograph 

 collection was continued by Assistant J. S. Daston before his nine- 

 month leave of absence. Mrs. Lenore B. Warner catalogued and 

 filed prints of the type-photograph collection, handled orders and 

 exchanges, continued the preparation of a Generic Index file for the 

 Macbride Collection, and indexed and prepared herbarium sheets 

 to be photographed and added to the general collection.
