and the specimens from the Alwin Berger herbarium. The 
flowering plants for the general herbarium, in addition to 
those from several parts of the United States, came mainly 
from Canada, Mexico, Cuba, Porto Rico, Jamaica, and the 
Philippine Islands. 
The herbarium comprising the local flora was materially 
increased by the addition of specimens collected within 
the hundred mile limit both by members of the staff and 
by others. 
Selections from specimens received during the year and 
previously, about 43,000 specimens of flowerless and flower- 
ing plants, were added to the herbarium. About 23,000 
sheets of herbarium paper were used, and a number of 
bulky specimens not suitable for keeping on sheets were 
filed away in cardboard boxes. 
The lichen herbarium was developed and many heretofore 
stored portions were made accessible through the voluntary 
assistance of Mr. W. C. Barbour, who personally devoted 
much time and attention to the work. 
Specimens received for the Columbia University her- 
barium were mounted and incorporated in that collection. 
Assistance and Investigations 
Dr. P. A. Rydberg, Curator, had charge of the herbarium 
collection of flowering plants, as in previous years. He 
continued his monographic work on the family Carduaceae 
for North American Flora, and a second part, containing 
genera of this family, was issued in July. A third part is 
nearly ready for publication. He also began monographic 
work on the family Fabaceae. Dr. Rydberg devoted a 
little attention, in continuation of former work, to the 
plants of the Rocky Mountain region, and prepared and 
published two papers, ‘‘Phytogeographic Notes on the 
Rocky Mountain Region IV. and V.” Two studies on 
Rosaceae, left over from preceding years, were also printed. 
A paper on the “‘Life Zones in the Rocky Mountains” was 
prepared for the Twentieth Anniversary of the Garden,
