Dr. Theodor Just, Chief Curator of Botany, pursued his studies 

 of living and fossil gymnosperms and of modern systems of classifi- 

 cation of the plant kingdom. During the year he initiated a pro- 

 gram of comparative studies of modern angiosperm pollen, in which 

 work he was aided by Miss Penelope Dunbar, Antioch College 

 student, and by Miss June Kolar and, later, Miss M. Dianne 

 Maurer, assistants. The special project of photographing the 

 entire Sesse" and Mocino collection, on loan from the Botanical 

 Garden in Madrid, was completed with the assistance of the Division 

 of Photography. 



Dr. Julian A. Steyermark, Curator of the Phanerogamic Her- 

 barium, spent considerable time in typing labels and sorting speci- 

 mens of his 1953 Venezuelan collections from Chimanta-tepui and 

 completed study of the Compositae of that mountain from his 1953 

 and 1955 collections. This family is well represented on this moun- 

 tain, two new genera and numerous new endemic species having 

 been found as a result of the two expeditions to Chimanta-tepui. 

 Various specialists are at work on the collections made during the 

 two expeditions, and already many new species of Bromeliaceae 

 and Gramineae have been found. A report will be published by 

 New York Botanical Garden, with Dr. Bassett Maguire, Dr. John J. 

 Wurdack, and Steyermark as co-authors. In addition to studying 

 his Venezuelan collections, Steyermark devoted his time to deter- 

 minations of miscellaneous collections from various parts of the 

 world and directed work on the illustrations for forthcoming parts 

 of Flora of Guatemala (Standley and Steyermark). The fourth 

 number of Contributions to the Flora of Venezuela (Steyermark and 

 collaborators) is in press. 



Dr. Francis Drouet, Curator of the Cryptogamic Herbarium, 

 did research on the classification of microscopic algae in collaboration 

 with William A. Daily, of Butler University. Dr. Hanford Tiffany 

 and Donald Richards, Research Associates, continued their studies 

 of Oedogoniaceae and bryophytes respectively. Dr. Gregorio T. 

 Velasquez, of the University of the Philippines at Quezon City, 

 Luis R. Almodovar, of San German, Puerto Rico, Mrs. Fay K. 

 Daily, of Butler University, and Edwin T. White, of the University 

 of Illinois Research and Educational Hospital, worked on various 

 problems of algal classification and distribution in the cryptogamic 

 herbarium of the Museum. 



Dr. John W. Thieret, Curator of Economic Botany, continued 

 his studies of the gross morphology of seeds of agricultural Legumi- 

 nosae and virtually completed his review of cycads as economic 

 plants. He devoted considerable time in the field to collection and
