National Herbarium 
M. 0. Malte, Chief Botanist, made considerable progress in the work 
on the flora of Arctic Canada. Many of the so-called critical genera were 
thoroughly studied and worked up, a task that was made possible by loans 
of Arctic plants from the Gray Herbarium, Cambridge, Mass., The New 
York Botanical Garden, New York, N.Y., The Danish Arctic Biological 
Station, Disko, Greenland, and the Botanical Division of the Government 
Museum, Stockholm, Sweden. Considerable time was also spent on dis- 
tribution of duplicates, renaming of specimens, and general readjustment 
of the herbarium. No field work was undertaken.
