liminary studies of the plants collected by Mr. R. S. Wil-

Mr. Geo. V. Nash, head gardener, has continued his work 
on the grasses and economic plants in general. Some special 
studies have been made upon the grasses of Porto Rico, the 
results of which were published as CONTRIBUTION 39. Critical 
examinations were also made of a number of other groups, 
that of the Fouquieriaceae being brought out as ConTRIBU- 
TION 42. 
My own work, outside of the time required for adminis- 
trative duties and the supervision of construction operations, 
has been devoted to aiding the several departments; the vast 
amount of material which has been received for the museums 
and herbarium has caused me to give special attention to the 
work of the curators in its proper determination and installa- 
tion. A paper on ‘* New or Noteworthy North American 
Crassulaceae,” prepared conjointly with Dr. J. N. Rose, of 
the United States National Museum, was published in the 
BULLETIN. 
Dr. L. M. Underwood, professor of botany, Columbia 
University, spent the period from January to May inclusive, 
in an extended field examination of the ferns of Cuba and 
Jamaica. The results of critical studies upon Botrychiun 
were published in the Bulletin of the Torrey Botanical Club 
for January, 1903, anda résumé of our knowledge of the ferns 
of the Philippines in the same journal for December, 1903. 
Dr. C. C. Curtis, tutor in botany, Columbia University, 
has been engaged in observations on the habits, occurrence 
and distribution of the forest trees of North America.
