the herbarium of the Royal Gardens at Kew, England. This 
work was interrupted by a visit to England made for the pur- 
pose of receiving and shipping to the Garden the Mitten col- 
lection of mosses and hepatics, as well as for the purpose of 
making comparisons of specimens at the museum of the 
Royal Gardens at Kew, and that of the British Museum, 
chiefly in connection with the work of continuing a report on 
Bolivian mosses, which was partly published several years 
ago. 
Dr. C. B. Robinson, Assistant Curator, since his appoint- 
ment on the first of July, has been occupied chiefly with the 
study of the flowering plants of the Philippine Islands, of 
which there are now over 10,000 sheets in the herbarium. He 
spent considerable time assisting in rearranging the Garden 
herbarium and also assisted in the demonstrations in nature- 
study courses carried on by the Garden in connection with the 
public schools of the city. He also spent his vacation explor- 
ing in Nova Scotia and brought back specimens of some 300 
species, which were determined by him on his return to the 
Garden. 
Dr. P. A. Rydberg, Curator, has, as heretofore, had 
charge of the herbarium of flowering plants. He has pre- 
pared a monograph of the first half of the family Rosaceae, 
which is to be published in a forthcoming part of the NorTH 
AMERICAN F Lora, and he has continued work on the Rocky 
Mountain Flora, which has been in preparation for some time. 
The Flora of Colorado, which was published by the Colorado 
Agricultural College, was issued as Bulletin no. 100 of 
the Experiment Station. ‘Studies on the Rocky Mountain 
Flora— XVI” was published in the Bulletin of the Torrey 
Botanical Club. Two other papers, * Grayta or Eremose- 
mtum” and ‘* Bossekia or Rubacer,” appeared in Torreya. 
Several weeks were spent by Dr. Rydberg at the National 
Herbarium for the purpose of studying the family Rosaceae 
and Rocky Mountain plants. He spent July in the field, 
mainly in the mountains of New York, and in the vicinity of 
Ottawa, Canada, devoting his time chiefly to the study of the 
native blackberries.
