This addition represents 18,940 herbarium sheets. No 
new equipment was added to the herbarium, but consider- 
able shifting of specimens was necessary owing to the un- 
even development of the different plant-groups. The 
complete rearrangement, on the Engler and Prantl se- 
quence, of the fern herbarium was completed and all the 
accumulated mounted fern specimens were distributed 
into their proper places. Work was concluded on the 
arrangement of the unmounted herbarium material so 
that specimens can be consulted when necessary or desir- 
able. 
The local flora herbarium was increased by the addition 
of selected specimens brought together by the personal 
efforts of members of the garden staff and by specially 
arranged exchanges. 
Investigations and Assistance 
The curatorial work was performed by the several 
curators and associate curators, some of whom have also 
participated in or cared for various other matters and all of 
whom have followed, incidentally, some line or lines of 
investigation connected with Garden activities. 
Dr. P. A. Rydberg, Curator, continued in charge of the 
herbarium of phanerogamic plants. The mechanical work 
this year has mainly been confined to the distributing of 
recently mounted specimens. His taxonomic work on the 
families Carduaceae and Fabaceae has been continued. 
Of the former, the manuscript for one part of North Ameri- 
can Flora has been delivered to the editor and enough for 
half a part in addition is practically ready. Of the Faba- 
ceae, one part, containing the second half of the tribe 
Pee alee. was published in January. The tribes Indi- 
gofereae and Galegeae are all but ready except the sub- 
tribe Astragalaneae of the latter. The manuscript pre- 
pared will almost be enough for two more parts. Two 
articles were published in the Bulletin of the Torrey Botanical 
Club: ‘‘Notes on Rosaceae XII,” and “ Phytogeographical 
Notes on the Rocky Mountain region XI.”
