Mr. Norman Taylor, Assistant Curator, devoted his 

 time largely to the study and collection of the local flora 

 by both herbarium and field work. Mr. Taylor prepared 

 an account of the trees of the Hudson River Valley, which 

 was published in the Hudson-Fulton Celebration issue of 

 the Descriptive Guide to the grounds, buildings and collec- 

 tions, and completed monographs of the four families of 

 the order Naiadales, which were published in "North 

 American Flora." The months of November and De- 

 cember were devoted by him to exploration in Santo Do- 

 mingo, West Indies. 



Dr. P. A. Rydberg, Curator, cared for the herbarium of 

 flowering plants. He has continued his work on the flora 

 of the Rocky Mountain region. His monographs of Spar- 

 ganiaceae, Elodeaceae and Hydrocharitaceae were pub- 

 lished in "North American Flora," while those of Balsami- 

 naceae and Limnanthaceae are ready to go to press. Dr. 

 Rydberg also revised a manuscript of the family Zygo- 

 phyllaceae for the same work, and printed several minor 

 papers in the Bulletin of the Torrey Botanical Club and 

 the Journal of the Garden. 



Mr. W. R. Maxon, an Assistant Curator of the United 

 States National Museum, spent two months in studying and 

 arranging the collections of ferns and in preparing mono- 

 graphs of several fern families for "North American Flora" 

 and some work has been done on the fern collections by 

 Mr. R. C. Benedict, Fellow in Botany, Columbia University. 



The writer, in addition to curatorial details, has con- 

 tinued his studies on North American plants, and the 

 relationships of plant genera and families. Further inves- 

 tigations on the flora of tropical Florida were prosecuted 

 both in the herbarium and in the field, the month of 

 January being spent in exploration. 



My monograph of Alismaceae was published in "North 

 American Flora," while that of the Malphighiaceae is 

 ready for publication. Respectfully submitted, 



J. K. Small, 

 Head Curator of the Museum and Herbarium.
