barium into three parts, namely, duplicates, American 

 plants, and Old World plants. Dr. Rydberg's studies 

 have been confined chiefly to the plants of the Rocky 

 Mountain region, concerning which several papers were 

 published, and the continuation of his monograph of the 

 Rosaceae, which is being printed in North American 

 Flora. His monographs of the Limnanthaceae and 

 Balsaminaceae and a revision of the Zygophyllaceae were 

 published in North American Flora early in the year. 



Mr. Norman Taylor, Assistant Curator, helped Dr. 

 Rydberg in caring for the herbarium of flowering plants. 

 He continued his studies in connection with the flora 

 within a radius of one hundred miles of New York City, 

 spending a part of the collecting season in the field, thus 

 securing specimens and making observations for the further 

 study of the subject. Mr. Taylor also gave three lectures 

 on the Garden course and acted as demonstrator in con- 

 nection with the nature-study courses in cooperation with 

 the public schools of the Borough of the Bronx. 



The writer, in addition to the time required on the 

 mechanical and scientific details connected with develop- 

 ment and care of the public museums and the herbarium, 

 published a monograph of the Malpighiaceae in North 

 American Flora, prepared a monograph of the North 

 American Simaroubaceae for the same work, and printed 

 minor papers on various botanical subjects. A portion 

 of January and February was spent in exploration on 

 Andros, in the Bahamas. Incidentally, he continued his 

 studies on the flora of the southeastern United States, 

 and particularly on the interrelation of different elements 

 of the flora of the extreme southern part of that region, 

 and their relation to the West Indian flora. He also had 

 many hundred camera-lucida drawings of flower-dissections 

 made on herbarium sheets in order to facilitate current 

 and future studies and monographic work. 

 Respectfully submitted, 



John K. Small, 

 Head Curator of the Museums and Herbarium.
