The main curatorial duties in connection with the flowering 
plants have as usual devolved on Dr. Rydberg, Assistant 
Curator. In addition to these duties he has continued his 
studies on the flora of the Rocky Mountain region and has 
also made progress in the manuscript of the manual of the 
plants of that region which he is preparing. Dr. Rydberg 
has completed the work on his ‘* Catalogue and Key to the 
Flora of Colorado.” He has also prepared monographs of 
several of the families for the forthcoming part of the North 
American Flora. His published papers for the year com- 
prise Nos. 11, 12 and 13 of his ‘* Studies on the Rocky 
Mountain Flora.” 
The writer devoted time not required for general curatorial 
duties to monographing the North American representatives 
of several plant families and to developing a collection of 
camera-lucida drawings of the floral parts of North Ameri- 
can plants. Exploration was prosecuted during two trips to 
Florida and special investigations on the flora of southern 
peninsular Florida were carried on, both by means of field 
work and the study of specimens secured while in the field. 
Respectfully submitted, 
J. K. Smaru, 
Curator of the Museums and Herbartum.
