The Curator Emeritus of Botany, Dr. B. E. Dahlgren, continued 

 classification of the genus Copemicia in collaboration with Dr. Sid- 

 ney F. Glassman of the University of Illinois (Navy Pier, Chicago). 

 Accompanied by L. W. Hansen, of Racine, Wisconsin, he visited a 

 parklike stand of species of Copernicia in northern Cuba early in the 

 year, and the two men have made numerous collections of flowers, 

 fruits, and leaves at intervals since then. Copemicia material assem- 

 bled in the Museum had so increased during recent years that addi- 

 tional space had to be provided to house all larger specimens. The 

 transfer and rearrangement of this material was entrusted to Karl 

 Siewers, of Chicago, who formerly had put into order the large South 

 American collections of Dr. K. S. Markley alone and with collabo- 

 rators from the staff of S. C. Johnson and Son, Incorporated. 



J. Francis Macbride, Curator of Peruvian Botany, continued his 

 studies of various families in preparation of additional parts of Flora 

 of Peru. He completed for publication another section, Halorrhaga- 

 ceae-Cuscuta. Dr. Rogers McVaugh, curator of the phanerogamic 

 herbarium of the University of Michigan, completed for publication 

 as part of Flora of Peru his treatment of the family Myrtaceae. De- 

 scriptions of numerous new species from Peru, prepared by Dr. 

 McVaugh, have been published by the Museum in Fieldiana. 



Dr. Earl E. Sherff, Research Associate in Systematic Botany, 

 identified large consignments of Hawaiian and East African plants, 

 mostly Compositae, and published two papers based on these (see 

 page 95). Early in the year Dr. Margery C. Carlson, Associate in 

 Botany, spent three and one-half months in Central America collect- 

 ing especially Loranthaecae. Her monograph on the genus Russelia 

 (Scrophulariaceae) was published during the year by the Museum 

 (see page 90) . 



Dr. Theodor Just, Chief Curator of Botany, continued compara- 

 tive studies of modem angiosperm pollen, in which work he was 

 assisted by Miss M. Dianne Maurer. Later in the year he extended 

 his pollen studies to the postglacial history of the vegetation of the 

 north-central states. In connection with his work on fossil and living 

 gymnosperms he visited the Ginkgo Petrified Forest State Park in 

 Washington (see page 34). Dr. Basheer Ahmed Razi, of Central 

 College, Bangalore, India, spent seven months in the herbarium as 

 an India Wheat Scholar under the auspices of the Conference Board
